What EXACTLY does the TUI use for that call label — the `mcpServers` config KEY (server name), the tool `name`, a tool `title` field, or `annotations.title` from the tools/list response? Does Claude Code prettify the server name (insert spaces, title-case), i.e. does `aicontrol` render as \"ai control\"?\n\n2. If I want the displayed label to be \"text panel\", what is the most reliable way:\n   (a) rename the server key (to what exactly — can it contain a space, hyphen, or must it be a single token? how does the chosen form render?), or\n   (b) set a `title` on the tool in the tools/list response (MCP spec `title` field or `annotations.title`), or\n   (c) some server-level displayName?\n\n3. If I rename the server key, does the permission allow-string change from `mcp__aicontrol__write_panel` to `mcp__<newkey>__write_panel` (and how are hyphens/spaces mangled)? \n\n4. Give the concrete recommended change (exact JSON in `.claude.json` and/or exact fields in the MCP `initialize`/`tools/list` response) that makes the call label show \"text panel\", plus the matching permission allow-string. Note any version differences (I'm on 2.1.207)."},"uuid":"b2169d47-7e33-4906-ae8d-3cbd579d5a19","timestamp":"2026-07-11T10:31:30.635Z","userType":"external","entrypoint":"cli","cwd":"/Users/marcus.hinz/claude-projects/ai-control","sessionId":"f7704328-4eb4-4f0f-bf42-da68abab401d","version":"2.1.207","gitBranch":"main"}

Directory connectors use the same MCP infrastructure as Claude Code, so you can add any remote server listed there with `claude mcp add`.\n\n<Warning>\n  Verify you trust each server before connecting it. Servers that fetch external content can expose you to [prompt injection risk](/en/security#protect-against-prompt-injection).\n</Warning>\n\nTo build your own server, see the [MCP server guide](https://modelcontextprotocol.io/docs/develop/build-server) for protocol fundamentals and the [Claude connector building docs](https://claude.com/docs/connectors/building) for authentication, testing, and Directory submission.\n\nYou can also have Claude scaffold a server for you with the official [`mcp-server-dev` plugin](https://github.com/anthropics/claude-plugins-official/tree/main/plugins/mcp-server-dev).\n\n<Steps>\n  <Step title=\"Install the plugin\">\n    In a Claude Code session, run:\n\n    ```\n    /plugin install mcp-server-dev@claude-plugins-official\n    ```\n\n    If Claude Code reports that the marketplace is not found, run `/plugin marketplace add anthropics/claude-plugins-official` first, then retry the install. Once installed, run `/reload-plugins` to activate it in the current session.\n  </Step>\n\n  <Step title=\"Run the build skill\">\n    ```\n    /mcp-server-dev:build-mcp-server\n    ```\n\n    Claude asks about your use case and scaffolds a remote HTTP or local stdio server.\n  </Step>\n</Steps>\n\n## Installing MCP servers\n\nMCP servers can be configured in several ways depending on your needs:\n\n### Option 1: Add a remote HTTP server\n\nHTTP servers are the recommended option for connecting to remote MCP servers. This is the most widely supported transport for cloud-based services.\n\n```bash theme={null}\n# Basic syntax\nclaude mcp add --transport http <name> <url>\n\n# Real example: Connect to Notion\nclaude mcp add --transport http notion https://mcp.notion.com/mcp\n\n# Example with Bearer token\nclaude mcp add --transport http secure-api https://api.example.com/mcp \\\n  --header \"Authorization: Bearer your-token\"\n```\n\nWhen configuring MCP servers via JSON in `.mcp.json`, `~/.claude.json`, or `claude mcp add-json`, the `type` field accepts `streamable-http` as an alias for `http`. The MCP specification uses the name `streamable-http` for this transport, so configurations copied from server documentation work without modification.\n\nA JSON entry that has a `url` but no `type` is a configuration error, because Claude Code reads an entry with no `type` as a stdio server. Claude Code skips that server and reports `MCP server \"<name>\" has a \"url\" but no \"type\"; add \"type\": \"http\" (or \"sse\" / \"ws\") to this entry`. Before v2.1.202, Claude Code reported this misconfiguration as `command: expected string, received undefined`.\n\n### Option 2: Add a remote SSE server\n\n<Warning>\n  The SSE (Server-Sent Events) transport is deprecated. Use HTTP servers instead, where available.\n</Warning>\n\n```bash theme={null}\n# Basic syntax\nclaude mcp add --transport sse <name> <url>\n\n# Real example: Connect to Asana\nclaude mcp add --transport sse asana https://mcp.asana.com/sse\n\n# Example with authentication header\nclaude mcp add --transport sse private-api https://api.company.com/sse \\\n  --header \"X-API-Key: your-key-here\"\n```\n\n### Option 3: Add a local stdio server\n\nStdio servers run as local processes on your machine. They're ideal for tools that need direct system access or custom scripts.\n\nClaude Code sets `CLAUDE_PROJECT_DIR` in the spawned server's environment to the project root, so your server can resolve project-relative paths without depending on the working directory. This is the same directory hooks receive in their `CLAUDE_PROJECT_DIR` variable. Read it from inside your server process, for example `process.env.CLAUDE_PROJECT_DIR` in Node or `os.environ[\"CLAUDE_PROJECT_DIR\"]` in Python.\n\n`CLAUDE_PROJECT_DIR` is the stable project root and doesn't change when you add or remove working directories mid-session. A server that limits its own filesystem access to a set of allowed directories should implement the MCP `roots/list` request instead. Claude Code answers `roots/list` with the session's launch directory plus every [additional working directory](/en/permissions#working-directories) you've granted with `--add-dir`, `/add-dir`, or the `additionalDirectories` setting. Claude Code sends `notifications/roots/list_changed` when that set changes. Before v2.1.203, `roots/list` returned only the launch directory and Claude Code didn't send `notifications/roots/list_changed`.\n\nThis variable is set in the server's environment, not in Claude Code's own environment, so referencing it via `${VAR}` expansion in a project- or user-scoped `.mcp.json` `command` or `args` requires a default such as `${CLAUDE_PROJECT_DIR:-.}`. Plugin-provided MCP configurations substitute `${CLAUDE_PROJECT_DIR}` directly and don't need the default.\n\n```bash theme={null}\n# Basic syntax\nclaude mcp add [options] <name> -- <command> [args...]\n\n# Real example: Add Airtable server\nclaude mcp add --env AIRTABLE_API_KEY=YOUR_KEY --transport stdio airtable \\\n  -- npx -y airtable-mcp-server\n```\n\n<Note>\n  **Important: Separate server arguments with `--`**\n\n  For stdio servers, the `--` (double dash) separates Claude's own options, such as `--transport`, `--env`, and `--scope`, from the command and arguments that run the server. Everything after `--` is passed to the server untouched.\n\n  For example:\n\n  * `claude mcp add --transport stdio myserver -- npx server` → runs `npx server`\n  * `claude mcp add --env KEY=value --transport stdio myserver -- python server.py --port 8080` → runs `python server.py --port 8080` with `KEY=value` in environment\n\n  Without `--`, Claude Code would try to parse the server's flags, like `--port` above, as its own options.\n\n  `--env` accepts multiple `KEY=value` pairs. If the server name comes directly after `--env`, the CLI reads the name as another pair and rejects it, so place at least one other option between `--env` and the server name, as in the examples above.\n</Note>\n\n### Option 4: Add a remote WebSocket server\n\nWebSocket servers hold a persistent bidirectional connection, which suits remote MCP servers that push events to Claude unprompted. Use HTTP instead when your server only responds to requests, since HTTP supports OAuth and the `claude mcp add --transport` flag, while WebSocket supports neither.\n\nConfigure WebSocket servers in `.mcp.json` or with `claude mcp add-json`:\n\n```bash theme={null}\nclaude mcp add-json events-server \\\n  '{\"type\":\"ws\",\"url\":\"wss://mcp.example.com/socket\",\"headers\":{\"Authorization\":\"Bearer YOUR_TOKEN\"}}'\n```\n\nThe `type: \"ws\"` entry accepts the same `url`, `headers`, `headersHelper`, `timeout`, and `alwaysLoad` fields as `http`. Authentication is header-only, so pass a static token in `headers` or generate one at connect time with [`headersHelper`](#use-dynamic-headers-for-custom-authentication). The `claude mcp add --transport` flag doesn't accept `ws`.\n\n### Managing your servers\n\nOnce configured, you can manage your MCP servers with these commands:\n\n```bash theme={null}\n# List all configured servers\nclaude mcp list\n\n# Get details for a specific server\nclaude mcp get github\n\n# Remove a server\nclaude mcp remove github\n\n# (within Claude Code) Check server status\n/mcp\n```\n\nProject-scoped servers from `.mcp.json` that are awaiting your approval appear in `claude mcp list` as `⏸ Pending approval`. Run `claude` interactively to review and approve them. `claude mcp get <name>` shows pending servers as `⏸ Pending approval` and rejected servers as `✗ Rejected`.\n\nAs of v2.1.196, `claude mcp list` and `claude mcp get` read `.mcp.json` approvals only from settings files that aren't checked into the repository until you trust the workspace by running `claude` in it and accepting the workspace trust dialog. A cloned repository can't approve its own servers: [`enableAllProjectMcpServers` or `enabledMcpjsonServers`](/en/settings#available-settings) committed to the project's `.claude/settings.json` is ignored in an untrusted folder, and the server stays at `⏸ Pending approval` instead of being connected and health-checked.\n\nApprovals from these sources still apply in an untrusted folder:\n\n* your user `~/.claude/settings.json`\n* managed settings\n* settings passed with `--settings`\n* `.claude/settings.local.json`, as long as git doesn't track it\n\nA `disabledMcpjsonServers` entry in any settings file still rejects the server.\n\nThe `/mcp` panel shows the tool count next to each connected server and flags servers that advertise the tools capability but expose no tools.\n\nIf your request needs tools from a server that is still connecting in the background, Claude waits for that server before continuing. With [tool search](#scale-with-mcp-tool-search) enabled, which is the default, the wait happens inside the `ToolSearch` call. In configurations without tool search, such as Google Cloud's Agent Platform, a custom `ANTHROPIC_BASE_URL`, or `ENABLE_TOOL_SEARCH=false`, Claude uses the `WaitForMcpServers` tool instead.\n\nSome server names are reserved for Claude Code's built-in servers: `workspace`, `claude-in-chrome`, `computer-use`, `Claude Preview`, and `Claude Browser`. If your configuration defines a server with a reserved name, Claude Code skips it at load time and shows a warning asking you to rename it. `claude mcp add` rejects a reserved name with an error.\n\n`Claude Preview` and `Claude Browser` both name the built-in server that the [Claude Code desktop app's preview pane](/en/desktop#preview-your-app) uses. Before v2.1.205, `Claude Browser` wasn't reserved, so a user-configured server could register under that name.\n\n### Dynamic tool updates\n\nClaude Code supports MCP `list_changed` notifications, allowing MCP servers to dynamically update their available tools, prompts, and resources without requiring you to disconnect and reconnect. When an MCP server sends a `list_changed` notification, Claude Code automatically refreshes the available capabilities from that server.\n\n### Automatic reconnection\n\nIf an HTTP or SSE server disconnects mid-session, Claude Code automatically reconnects with exponential backoff: up to five attempts, starting at a one-second delay and doubling each time. The server appears as pending in `/mcp` while reconnection is in progress. After five failed attempts the server is marked as failed and you can retry manually from `/mcp`. Stdio servers are local processes and are not reconnected automatically.\n\nThe same backoff applies when an HTTP or SSE server fails its initial connection at startup. As of v2.1.121, Claude Code retries the initial connection up to three times on transient errors such as a 5xx response, a connection refused, or a timeout, then marks the server as failed if it still can't connect. Authentication and not-found errors are not retried because they require a configuration change to resolve.\n\nWhen a configured server fails to connect, Claude Code tells Claude which server failed and its connection error, including in `ToolSearch` results that find no matching tool, so Claude reports the connection failure in its response. Requires [tool search](#scale-with-mcp-tool-search), which is enabled by default. In configurations without tool search, such as a custom `ANTHROPIC_BASE_URL`, `ENABLE_TOOL_SEARCH=false`, or a Haiku model, and on Amazon Bedrock, Google Cloud's Agent Platform, and Microsoft Foundry, Claude Code doesn't report failed server connections to Claude. Before v2.1.205, Claude Code didn't pass connection errors to Claude, and Claude could respond as if the failed server's tools were never configured.\n\nAs of v2.1.191, the capability discovery requests that run after a successful connection, such as `tools/list`, `prompts/list`, and `resources/list`, also retry transient network and server errors up to three times with short backoff. Authentication errors, 4xx responses, and request timeouts are not retried.\n\n### Push messages with channels\n\nAn MCP server can also push messages directly into your session so Claude can react to external events like CI results, monitoring alerts, or chat messages. To enable this, your server declares the `claude/channel` capability and you opt it in with the `--channels` flag at startup. See [Channels](/en/channels) to use an officially supported channel, or [Channels reference](/en/channels-reference) to build your own.\n\n<Tip>\n  Tips:\n\n  * Use the `-s` or `--scope` flag to specify where the configuration is stored:\n    * `local` (default): available only to you in the current project. Older versions called this scope `project`\n    * `project`: shared with everyone in the project via the `.mcp.json` file\n    * `user`: available to you across all projects. Older versions called this scope `global`\n  * Set environment variables with `-e` or `--env` flags (for example, `-e KEY=value`)\n  * The `--transport` and `--header` flags also accept `-t` and `-H` short forms\n  * Configure MCP server startup timeout using the `MCP_TIMEOUT` environment variable (for example, `MCP_TIMEOUT=10000 claude` sets a 10-second timeout)\n  * Set a per-server tool execution timeout by adding a `timeout` field in milliseconds to that server's `.mcp.json` entry, for example `\"timeout\": 600000` for ten minutes. This overrides the `MCP_TOOL_TIMEOUT` environment variable for that server only\n  * Claude Code displays a warning when MCP tool output exceeds 10,000 tokens. To increase this limit, set the `MAX_MCP_OUTPUT_TOKENS` environment variable (for example, `MAX_MCP_OUTPUT_TOKENS=50000`)\n  * Use `/mcp` to authenticate with remote servers that require OAuth 2.0 authentication\n</Tip>\n\nThe per-server `timeout` is a hard wall-clock limit per tool call, and progress notifications from the server don't extend it. Values below 1000 are ignored and fall through to `MCP_TOOL_TIMEOUT`, or to its default of about 28 hours when that variable is unset. {/* min-version: 2.1.162 */}Before v2.1.162, values below 1000 were floored to one second instead.\n\nA per-server `timeout` of at least 1000 also acts as a floor on the idle timeout described below: Claude Code never aborts that server's tool calls for idleness sooner than the per-server `timeout`. Requires Claude Code v2.1.203 or later.\n\nFor HTTP and SSE servers, the per-request fetch first-byte budget has a 60-second minimum.\n\nA tool call to an MCP server that sends no response and no progress notification for the idle window aborts with an error instead of waiting for the wall-clock limit. The idle timeout requires Claude Code v2.1.187 or later. {/* min-version: 2.1.203 */}It applies to every server type except IDE servers and SDK in-process servers. The idle window defaults to five minutes for HTTP, SSE, WebSocket, and [claude.ai connector](#use-mcp-servers-from-claude-ai) servers, and to 30 minutes for stdio servers. Before v2.1.203, stdio servers were exempt from the idle timeout.\n\nSet the [`CLAUDE_CODE_MCP_TOOL_IDLE_TIMEOUT`](/en/env-vars) environment variable in milliseconds to change the idle window, or set it to `0` to disable the check.\n\n### Plugin-provided MCP servers\n\n[Plugins](/en/plugins) can bundle MCP servers, automatically providing tools and integrations when the plugin is enabled. Plugin MCP servers work identically to user-configured servers.\n\n**How plugin MCP servers work**:\n\n* Plugins define MCP servers in `.mcp.json` at the plugin root or inline in `plugin.json`\n* When a plugin is enabled, its MCP servers start automatically\n* Plugin MCP tools appear alongside manually configured MCP tools\n* Plugin servers are managed through plugin installation, not `/mcp` commands\n\n**Example plugin MCP configuration**:\n\nIn `.mcp.json` at plugin root:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"database-tools\": {\n      \"command\": \"${CLAUDE_PLUGIN_ROOT}/servers/db-server\",\n      \"args\": [\"--config\", \"${CLAUDE_PLUGIN_ROOT}/config.json\"],\n      \"env\": {\n        \"DB_URL\": \"${DB_URL}\"\n      }\n    }\n  }\n}\n```\n\nOr inline in `plugin.json`:\n\n```json theme={null}\n{\n  \"name\": \"my-plugin\",\n  \"mcpServers\": {\n    \"plugin-api\": {\n      \"command\": \"${CLAUDE_PLUGIN_ROOT}/servers/api-server\",\n      \"args\": [\"--port\", \"8080\"]\n    }\n  }\n}\n```\n\n**Plugin MCP features**:\n\n* **Automatic lifecycle**: at session startup, servers for enabled plugins connect automatically. If you enable or disable a plugin during a session, run `/reload-plugins` to connect or disconnect its MCP servers\n* **Environment variables**: use `${CLAUDE_PLUGIN_ROOT}` for bundled plugin files, `${CLAUDE_PLUGIN_DATA}` for [persistent state](/en/plugins-reference#persistent-data-directory) that survives plugin updates, and `${CLAUDE_PROJECT_DIR}` for the stable project root\n* **User environment access**: access to the same environment variables as manually configured servers\n* **Multiple transport types**: support for stdio, SSE, HTTP, and WebSocket transports, though transport support may vary by server\n\n**Viewing plugin MCP servers**:\n\n```bash theme={null}\n# Within Claude Code, see all MCP servers including plugin ones\n/mcp\n```\n\nPlugin servers appear in the list with indicators showing they come from plugins.\n\n**Plugin MCP tool names**:\n\nTools from a plugin-bundled MCP server include both the plugin name and the server key in their callable name. The full form is `mcp__plugin_<plugin-name>_<server-name>__<tool-name>`, where any character outside `A-Z`, `a-z`, `0-9`, `_`, and `-` is replaced with `_`. For the `database-tools` server bundled in a plugin named `my-plugin`, a `query` tool is callable as:\n\n```\nmcp__plugin_my-plugin_database-tools__query\n```\n\nUse this full name when referencing the tool in [permission rules](/en/permissions), a skill's `allowed-tools` list, a [subagent's `tools` field](/en/sub-agents#available-tools), or a [hook matcher](/en/hooks#match-mcp-tools). A hook matcher written against the bare server key, such as `mcp__database-tools__.*`, never fires for a plugin-bundled server.\n\nThe server itself registers under the scoped name `plugin:<plugin-name>:<server-name>`, such as `plugin:my-plugin:database-tools`. Use that name where a configured server name is expected, such as an [`mcp_tool` hook's `server` field](/en/hooks#mcp-tool-hook-fields).\n\n**Benefits of plugin MCP servers**:\n\n* **Bundled distribution**: tools and servers packaged together\n* **Automatic setup**: no manual MCP configuration needed\n* **Team consistency**: everyone gets the same tools when the plugin is installed\n\nSee the [plugin components reference](/en/plugins-reference#mcp-servers) for details on bundling MCP servers with plugins.\n\n## MCP installation scopes\n\nMCP servers can be configured at three scopes. The scope you choose controls which projects the server loads in and whether the configuration is shared with your team. Administrators can also deploy servers at the enterprise level via [managed configuration](#managed-mcp-configuration).\n\n| Scope                     | Loads in             | Shared with team         | Stored in                   |\n| ------------------------- | -------------------- | ------------------------ | --------------------------- |\n| [Local](#local-scope)     | Current project only | No                       | `~/.claude.json`            |\n| [Project](#project-scope) | Current project only | Yes, via version control | `.mcp.json` in project root |\n| [User](#user-scope)       | All your projects    | No                       | `~/.claude.json`            |\n\n### Local scope\n\nLocal scope is the default. A local-scoped server loads only in the project where you added it and stays private to you. Claude Code stores it in `~/.claude.json` under that project's path, so the same server won't appear in your other projects. Use local scope for personal development servers, experimental configurations, or servers with credentials you don't want in version control.\n\n<Note>\n  The term \"local scope\" for MCP servers differs from general local settings. MCP local-scoped servers are stored in `~/.claude.json` (your home directory), while general local settings use `.claude/settings.local.json` (in the project directory). See [Settings](/en/settings#settings-files) for details on settings file locations.\n</Note>\n\n```bash theme={null}\n# Add a local-scoped server (default)\nclaude mcp add --transport http stripe https://mcp.stripe.com\n\n# Explicitly specify local scope\nclaude mcp add --transport http stripe --scope local https://mcp.stripe.com\n```\n\nThe command writes the server into the entry for your current project inside `~/.claude.json`. The example below shows the result when you run it from `/path/to/your/project`:\n\n```json theme={null}\n{\n  \"projects\": {\n    \"/path/to/your/project\": {\n      \"mcpServers\": {\n        \"stripe\": {\n          \"type\": \"http\",\n          \"url\": \"https://mcp.stripe.com\"\n        }\n      }\n    }\n  }\n}\n```\n\n### Project scope\n\nProject-scoped servers enable team collaboration by storing configurations in a `.mcp.json` file at your project's root directory. This file is designed to be checked into version control, ensuring all team members have access to the same MCP tools and services. When you add a project-scoped server, Claude Code automatically creates or updates this file with the appropriate configuration structure.\n\n```bash theme={null}\n# Add a project-scoped server\nclaude mcp add --transport http paypal --scope project https://mcp.paypal.com/mcp\n```\n\nThe resulting `.mcp.json` file follows a standardized format:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"shared-server\": {\n      \"command\": \"/path/to/server\",\n      \"args\": [],\n      \"env\": {}\n    }\n  }\n}\n```\n\nFor security reasons, Claude Code prompts for approval before using project-scoped servers from `.mcp.json` files. If you need to reset these approval choices, use the `claude mcp reset-project-choices` command.\n\n### User scope\n\nUser-scoped servers are stored in `~/.claude.json` and provide cross-project accessibility, making them available across all projects on your machine while remaining private to your user account. This scope works well for personal utility servers, development tools, or services you frequently use across different projects.\n\n```bash theme={null}\n# Add a user server\nclaude mcp add --transport http hubspot --scope user https://mcp.hubspot.com/anthropic\n```\n\n### Scope hierarchy and precedence\n\nWhen the same server is defined in more than one place, Claude Code connects to it once, using the definition from the highest-precedence source. The entire server entry from that source is used; fields are not merged across scopes.\n\n1. Local scope\n2. Project scope\n3. User scope\n4. [Plugin-provided servers](/en/plugins)\n5. [claude.ai connectors](#use-mcp-servers-from-claude-ai)\n\nThe three scopes match duplicates by name. Plugins and connectors match by endpoint, so one that points at the same URL or command as a server above is treated as a duplicate.\n\n### Environment variable expansion in `.mcp.json`\n\nClaude Code supports environment variable expansion in `.mcp.json` files, allowing teams to share configurations while maintaining flexibility for machine-specific paths and sensitive values like API keys.\n\n**Supported syntax:**\n\n* `${VAR}`: expands to the value of environment variable `VAR`\n* `${VAR:-default}`: expands to `VAR` if set, otherwise uses `default`\n\n**Expansion locations:**\nEnvironment variables can be expanded in:\n\n* `command`: the server executable path\n* `args`: command-line arguments\n* `env`: environment variables passed to the server\n* `url`: for HTTP server types\n* `headers`: for HTTP server authentication\n\n**Example with variable expansion:**\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"api-server\": {\n      \"type\": \"http\",\n      \"url\": \"${API_BASE_URL:-https://api.example.com}/mcp\",\n      \"headers\": {\n        \"Authorization\": \"Bearer ${API_KEY}\"\n      }\n    }\n  }\n}\n```\n\nIf a required environment variable isn't set and has no default value, Claude Code fails to parse the config.\n\n## Practical examples\n\n### Example: Monitor errors with Sentry\n\n```bash theme={null}\nclaude mcp add --transport http sentry https://mcp.sentry.dev/mcp\n```\n\nAuthenticate with your Sentry account:\n\n```text theme={null}\n/mcp\n```\n\nThen debug production issues:\n\n```text theme={null}\nWhat are the most common errors in the last 24 hours?\n```\n\n```text theme={null}\nShow me the stack trace for error ID abc123\n```\n\n```text theme={null}\nWhich deployment introduced these new errors?\n```\n\n### Example: Connect to GitHub for code reviews\n\nGitHub's remote MCP server authenticates with a GitHub personal access token passed as a header. To get one, open your [GitHub token settings](https://github.com/settings/personal-access-tokens), generate a new fine-grained token with access to the repositories you want Claude to work with, then add the server:\n\n```bash theme={null}\nclaude mcp add --transport http github https://api.githubcopilot.com/mcp/ \\\n  --header \"Authorization: Bearer YOUR_GITHUB_PAT\"\n```\n\nThen work with GitHub:\n\n```text theme={null}\nReview PR #456 and suggest improvements\n```\n\n```text theme={null}\nCreate a new issue for the bug we just found\n```\n\n```text theme={null}\nShow me all open PRs assigned to me\n```\n\n### Example: Query your PostgreSQL database\n\n```bash theme={null}\nclaude mcp add --transport stdio db -- npx -y @bytebase/dbhub \\\n  --dsn \"postgresql://readonly:pass@prod.db.com:5432/analytics\"\n```\n\nThen query your database naturally:\n\n```text theme={null}\nWhat's our total revenue this month?\n```\n\n```text theme={null}\nShow me the schema for the orders table\n```\n\n```text theme={null}\nFind customers who haven't made a purchase in 90 days\n```\n\n## Authenticate with remote MCP servers\n\nMany cloud-based MCP servers require authentication. Claude Code supports OAuth 2.0 for secure connections.\n\nClaude Code marks a remote server as needing authentication when the server responds with `401 Unauthorized` or `403 Forbidden`. Either status code flags the server in `/mcp` so you can complete the OAuth flow.\n\nAs of v2.1.195, when a token refresh fails because the server rejects the stored refresh token, Claude Code immediately shows a notice pointing at `/mcp`. The connected server's menu there offers Re-authenticate, so you can sign in again before the next tool call fails.\n\nA custom server that returns a `WWW-Authenticate` header pointing to its authorization server gets the same automatic discovery as any other remote server.\n\nAs of v2.1.193, Claude Code also shows a startup notice when one or more configured servers need authentication, so you don't have to open `/mcp` to discover which servers need sign-in.\n\nIn non-interactive mode there's no `/mcp` panel, so Claude Code can't run the OAuth flow for you. As of v2.1.196, when a configured server needs authentication during a `claude -p` or Agent SDK run with [tool search](#scale-with-mcp-tool-search) enabled, which is the default, Claude Code tells Claude that the server's tools are unavailable until you authorize it. Claude can then name the server that needs sign-in instead of responding as if the server weren't configured. Complete the sign-in from an interactive session with `/mcp` or `claude mcp login <name>`.\n\nIf you configured `headers.Authorization` for the server and the server rejects that header, Claude Code reports the connection as failed instead of falling back to OAuth. Check that the token is valid for the MCP endpoint, or remove the header to use the OAuth flow.\n\n<Steps>\n  <Step title=\"Add the server that requires authentication\">\n    For example:\n\n    ```bash theme={null}\n    claude mcp add --transport http sentry https://mcp.sentry.dev/mcp\n    ```\n  </Step>\n\n  <Step title=\"Use the /mcp command within Claude Code\">\n    In Claude Code, use the command:\n\n    ```text theme={null}\n    /mcp\n    ```\n\n    Then follow the steps in your browser to log in.\n  </Step>\n</Steps>\n\n<Tip>\n  Tips:\n\n  * Authentication tokens are stored securely and refreshed automatically\n  * Use \"Clear authentication\" in the `/mcp` menu to revoke access\n  * If your browser doesn't open automatically, copy the provided URL and open it manually\n  * If the browser redirect fails with a connection error after authenticating, paste the full callback URL from your browser's address bar into the URL prompt that appears in Claude Code\n  * OAuth authentication works with HTTP servers\n</Tip>\n\n### Authenticate from the command line\n\nFrom v2.1.186, `claude mcp login <name>` runs a configured server's OAuth flow directly from your shell, so you don't need to open the `/mcp` panel inside a session.\n\n```bash theme={null}\nclaude mcp login sentry\n```\n\nTo clear stored credentials later, run `claude mcp logout <name>`.\n\nAs of v2.1.191, the command detects when no local browser is available, such as during an SSH session or on Linux without a display server, and prints the authorization URL instead of trying to open a browser. Open the URL on your local machine, then paste the full redirect URL from your browser's address bar back at the prompt. The command needs an interactive terminal for the paste step, so connect with `ssh -t`. Pass `--no-browser` to force the URL prompt even when a local browser is detected.\n\n```bash theme={null}\nclaude mcp login sentry --no-browser\n```\n\n### Use a fixed OAuth callback port\n\nSome MCP servers require a specific redirect URI registered in advance. By default, Claude Code picks a random available port for the OAuth callback. Use `--callback-port` to fix the port so it matches a pre-registered redirect URI of the form `http://localhost:PORT/callback`.\n\nYou can use `--callback-port` on its own (with dynamic client registration) or together with `--client-id` (with pre-configured credentials).\n\n```bash theme={null}\n# Fixed callback port with dynamic client registration\nclaude mcp add --transport http \\\n  --callback-port 8080 \\\n  my-server https://mcp.example.com/mcp\n```\n\n### Use pre-configured OAuth credentials\n\nSome MCP servers don't support automatic OAuth setup via Dynamic Client Registration. If you see an error like \"Incompatible auth server: does not support dynamic client registration,\" the server requires pre-configured credentials. Claude Code also supports servers that use a Client ID Metadata Document (CIMD) instead of Dynamic Client Registration, and discovers these automatically. If automatic discovery fails, register an OAuth app through the server's developer portal first, then provide the credentials when adding the server.\n\n<Steps>\n  <Step title=\"Register an OAuth app with the server\">\n    Create an app through the server's developer portal and note your client ID and client secret.\n\n    Many servers also require a redirect URI. If so, choose a port and register a redirect URI in the format `http://localhost:PORT/callback`.

They have no effect on stdio servers\n  * Use `claude mcp get <name>` to verify that OAuth credentials are configured for a server\n</Tip>\n\n### Override OAuth metadata discovery\n\nPoint Claude Code at a specific OAuth authorization server metadata URL to bypass the default discovery chain. Set `authServerMetadataUrl` when the MCP server's standard endpoints error, or when you want to route discovery through an internal proxy. By default, Claude Code first checks RFC 9728 Protected Resource Metadata at `/.well-known/oauth-protected-resource`, then falls back to RFC 8414 authorization server metadata at `/.well-known/oauth-authorization-server`.\n\nSet `authServerMetadataUrl` in the `oauth` object of your server's config in `.mcp.json`:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"my-server\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.example.com/mcp\",\n      \"oauth\": {\n        \"authServerMetadataUrl\": \"https://auth.example.com/.well-known/openid-configuration\"\n      }\n    }\n  }\n}\n```\n\nThe URL must use `https://`. `authServerMetadataUrl` requires Claude Code v2.1.64 or later. The metadata URL's `scopes_supported` overrides the scopes the upstream server advertises.\n\n### Restrict OAuth scopes\n\nSet `oauth.scopes` to pin the scopes Claude Code requests during the authorization flow. This is the supported way to restrict an MCP server to a security-team-approved subset when the upstream authorization server advertises more scopes than you want to grant. The value is a single space-separated string, matching the `scope` parameter format in RFC 6749 §3.3.\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"slack\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.slack.com/mcp\",\n      \"oauth\": {\n        \"scopes\": \"channels:read chat:write search:read\"\n      }\n    }\n  }\n}\n```\n\n`oauth.scopes` takes precedence over both `authServerMetadataUrl` and the scopes the server discovers at `/.well-known`. Leave it unset to let the MCP server determine the requested scope set.\n\nAs of v2.1.196, when `oauth.scopes` isn't set, Claude Code requests the scope provided by the server's `WWW-Authenticate` header or its protected resource metadata, and sends no `scope` parameter when neither provides one. It no longer requests the full `scopes_supported` catalog from automatically discovered authorization server metadata. Requesting that catalog made identity providers that advertise admin-only or template scopes reject the authorization request with an `invalid_scope` error. Metadata fetched from a configured `authServerMetadataUrl` still supplies its `scopes_supported` as the requested scopes.\n\nIf the authorization server advertises `offline_access` in `scopes_supported`, Claude Code appends it to the pinned scopes so the access token can be refreshed without a new browser sign-in.\n\nIf the server later returns a 403 `insufficient_scope` for a tool call, Claude Code re-authenticates with the same pinned scopes. Widen `oauth.scopes` when a tool you need requires a scope outside the pinned set.\n\n### Use dynamic headers for custom authentication\n\nIf your MCP server uses an authentication scheme other than OAuth, such as Kerberos, short-lived tokens, or an internal SSO, use `headersHelper` to generate request headers at connection time. Claude Code runs the command and merges its output into the connection headers.\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"internal-api\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.internal.example.com\",\n      \"headersHelper\": \"/opt/bin/get-mcp-auth-headers.sh\"\n    }\n  }\n}\n```\n\nThe command can also be inline:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"internal-api\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.internal.example.com\",\n      \"headersHelper\": \"echo '{\\\"Authorization\\\": \\\"Bearer '\\\"$(get-token)\\\"'\\\"}'\"\n    }\n  }\n}\n```\n\n**Requirements:**\n\n* The command must write a JSON object of string key-value pairs to stdout\n* The command runs in a shell with a 10-second timeout\n* Dynamic headers override any static `headers` with the same name\n\nThe helper runs fresh on each connection, at session start and on reconnect. There is no caching, so your script is responsible for any token reuse.\n\nAs of v2.1.193, if a tool call returns `401 Unauthorized` or `403 Forbidden`, Claude Code automatically re-runs the helper, reconnects with the fresh headers, and retries the call once. Claude Code marks the server as needing authentication in `/mcp` only if that retry also fails.\n\nClaude Code sets these environment variables when executing the helper:\n\n| Variable                      | Value                                                                                                        |\n| :---------------------------- | :----------------------------------------------------------------------------------------------------------- |\n| `CLAUDE_CODE_MCP_SERVER_NAME` | the name of the MCP server                                                                                   |\n| `CLAUDE_CODE_MCP_SERVER_URL`  | the URL of the MCP server                                                                                    |\n| `CLAUDE_PLUGIN_ROOT`          | the plugin's root directory. Set only when a [plugin](/en/plugins-reference#mcp-servers) provides the server |\n\nUse these to write a single helper script that serves multiple MCP servers.\n\nFor a plugin-provided server, the helper also runs with its working directory set to the plugin root, so a relative `headersHelper` path resolves inside the plugin directory rather than against the session's working directory. Requires Claude Code v2.1.195 or later.\n\n<Note>\n  `headersHelper` executes arbitrary shell commands. When defined at project or local scope, it only runs after you accept the workspace trust dialog.\n</Note>\n\n## Add MCP servers from JSON configuration\n\nIf you have a JSON configuration for an MCP server, you can add it directly:\n\n<Steps>\n  <Step title=\"Add an MCP server from JSON\">\n    ```bash theme={null}\n    # Basic syntax\n    claude mcp add-json <name> '<json>'\n\n    # Example: Adding an HTTP server with JSON configuration\n    claude mcp add-json weather-api '{\"type\":\"http\",\"url\":\"https://api.weather.com/mcp\",\"headers\":{\"Authorization\":\"Bearer token\"}}'\n\n    # Example: Adding a stdio server with JSON configuration\n    claude mcp add-json local-weather '{\"type\":\"stdio\",\"command\":\"/path/to/weather-cli\",\"args\":[\"--api-key\",\"abc123\"],\"env\":{\"CACHE_DIR\":\"/tmp\"}}'\n\n    # Example: Adding an HTTP server with pre-configured OAuth credentials\n    claude mcp add-json my-server '{\"type\":\"http\",\"url\":\"https://mcp.example.com/mcp\",\"oauth\":{\"clientId\":\"your-client-id\",\"callbackPort\":8080}}' --client-secret\n    ```\n  </Step>\n\n  <Step title=\"Verify the server was added\">\n    ```bash theme={null}\n    claude mcp get weather-api\n    ```\n  </Step>\n</Steps>\n\n<Tip>\n  Tips:\n\n  * Make sure the JSON is properly escaped in your shell\n  * The JSON must conform to the MCP server configuration schema\n  * You can use `--scope user` to add the server to your user configuration instead of the project-specific one\n</Tip>\n\n## Import MCP servers from Claude Desktop\n\nIf you've already configured MCP servers in Claude Desktop, you can import them:\n\n<Steps>\n  <Step title=\"Import servers from Claude Desktop\">\n    ```bash theme={null}\n    # Basic syntax \n    claude mcp add-from-claude-desktop \n    ```\n  </Step>\n\n  <Step title=\"Select which servers to import\">\n    After running the command, you'll see an interactive dialog that allows you to select which servers you want to import.\n  </Step>\n\n  <Step title=\"Verify the servers were imported\">\n    ```bash theme={null}\n    claude mcp list \n    ```\n  </Step>\n</Steps>\n\nServer names added through `claude mcp` commands can contain only letters, numbers, hyphens, and underscores. Claude Desktop doesn't apply that restriction, so a Claude Desktop server whose name contains any other character, such as a space, can't be imported. The import reports each name it rejects and still imports the other servers you selected. Before v2.1.205, the first invalid name stopped the import and none of the selected servers were added.\n\n<Tip>\n  Tips:\n\n  * This feature only works on macOS and Windows Subsystem for Linux (WSL)\n  * It reads the Claude Desktop configuration file from its standard location on those platforms\n  * Use the `--scope user` flag to add servers to your user configuration\n  * Imported servers keep the same names as in Claude Desktop when the name contains only letters, numbers, hyphens, and underscores. Claude Code reports a server whose name contains any other character and skips it\n  * If servers with the same names already exist, they get a numerical suffix (for example, `server_1`)\n</Tip>\n\n## Use MCP servers from claude.ai\n\nIf you've logged into Claude Code with a [claude.ai](https://claude.ai) account, MCP servers you've added in claude.ai are automatically available in Claude Code:\n\n<Steps>\n  <Step title=\"Configure MCP servers in claude.ai\">\n    Add servers at [claude.ai/customize/connectors](https://claude.ai/customize/connectors). On Team and Enterprise plans, only admins can add servers.\n  </Step>\n\n  <Step title=\"Authenticate the MCP server\">\n    Complete any required authentication steps in claude.ai.\n  </Step>\n\n  <Step title=\"View and manage servers in Claude Code\">\n    In Claude Code, use the command:\n\n    ```text theme={null}\n    /mcp\n    ```\n\n    Servers from claude.ai appear in the list with indicators showing they come from claude.ai.\n  </Step>\n</Steps>\n\nFrom v2.1.161, connectors you have never signed in to are collapsed behind a `Show unused connectors` row at the end of the claude.ai section, so an organization-provisioned list doesn't fill the panel. Select the row to expand them. A connector you signed in to before stays visible even when it currently needs re-authentication.\n\nConnectors from claude.ai are fetched only when your active [authentication method](/en/authentication#authentication-precedence) is your claude.ai subscription. They aren't loaded when `ANTHROPIC_API_KEY`, `ANTHROPIC_AUTH_TOKEN`, `apiKeyHelper`, or a third-party provider such as Amazon Bedrock or Google Cloud's Agent Platform is active, even if you previously ran `/login`.\n\nIf `/mcp` doesn't list a connector you added, run `/status` to confirm which authentication method is active, unset that environment variable or remove the `apiKeyHelper` setting, then run `/login` to select your claude.ai account.\n\nA server you've added in Claude Code takes [precedence](#scope-hierarchy-and-precedence) over a claude.ai connector that points at the same URL. When this happens, `/mcp` lists the connector as hidden and shows how to remove the duplicate if you'd rather use the connector.\n\nSome Anthropic-hosted connectors, such as Microsoft 365, Gmail, and Google Calendar, don't support local OAuth from Claude Code because the upstream identity provider only accepts the redirect URL that claude.ai registered. From v2.1.162, authenticating one of these hosts in `/mcp` shows a message directing you to connect it at Settings → Connectors on claude.ai instead. Once connected there, the connector appears in Claude Code automatically.\n\n### Disable claude.ai connectors\n\nTo disable claude.ai MCP servers in Claude Code, set [`disableClaudeAiConnectors`](/en/settings#available-settings) to `true` in any settings scope:\n\n```json theme={null}\n{\n  \"disableClaudeAiConnectors\": true\n}\n```\n\nThis setting uses any-source-true semantics: `true` in any settings source takes precedence. A checked-in project `.claude/settings.json` can opt a repository out of cloud connectors, but a project-level `false` can't re-enable connectors that a user- or policy-level `true` has disabled. Servers passed explicitly via `--mcp-config` are unaffected.\n\nYou can also set the `ENABLE_CLAUDEAI_MCP_SERVERS` environment variable to `false`, which has the same effect for the current shell session:\n\n```bash theme={null}\nENABLE_CLAUDEAI_MCP_SERVERS=false claude\n```\n\nTo block individual claude.ai connectors instead of all of them, add them to [`deniedMcpServers`](/en/managed-mcp) by name or by URL pattern. For example, a `serverName` entry of `\"claude.ai Slack\"` blocks the Slack connector. To toggle a connector on or off for the current project only, use the `/mcp` panel.\n\n<Note>\n  These client-side settings govern local Claude Code sessions. In [Claude Code on the web](/en/claude-code-on-the-web) sessions, claude.ai connectors are provisioned by the remote host and arrive as explicit `--mcp-config` entries, so `disableClaudeAiConnectors` doesn't apply there. Connector URLs are also rewritten through the session proxy, so a `deniedMcpServers` `serverUrl` pattern targeting the vendor URL won't match. Manage which connectors a cloud session can use from your claude.ai organization settings.\n</Note>\n\n## Use Claude Code as an MCP server\n\nYou can use Claude Code itself as an MCP server that other applications can connect to:\n\n```bash theme={null}\n# Start Claude as a stdio MCP server\nclaude mcp serve\n```\n\nYou can use this in Claude Desktop by adding this configuration to claude\\_desktop\\_config.json:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"claude-code\": {\n      \"type\": \"stdio\",\n      \"command\": \"claude\",\n      \"args\": [\"mcp\", \"serve\"],\n      \"env\": {}\n    }\n  }\n}\n```\n\n<Warning>\n  **Configuring the executable path**: the `command` field must reference the Claude Code executable. If the `claude` command is not in your system's PATH, you'll need to specify the full path to the executable.\n\n  To find the full path:\n\n  ```bash theme={null}\n  which claude\n  ```\n\n  Then use the full path in your configuration:\n\n  ```json theme={null}\n  {\n    \"mcpServers\": {\n      \"claude-code\": {\n        \"type\": \"stdio\",\n        \"command\": \"/full/path/to/claude\",\n        \"args\": [\"mcp\", \"serve\"],\n        \"env\": {}\n      }\n    }\n  }\n  ```\n\n  Without the correct executable path, you'll encounter errors like `spawn claude ENOENT`.\n</Warning>\n\n<Tip>\n  Tips:\n\n  * The server provides access to Claude's tools like View, Edit, LS, etc.\n  * In Claude Desktop, try asking Claude to read files in a directory, make edits, and more.\n  * This MCP server only exposes Claude Code's tools to your MCP client, so your own client is responsible for implementing user confirmation for individual tool calls.\n</Tip>\n\n## MCP output limits and warnings\n\nWhen MCP tools produce large outputs, Claude Code helps manage the token usage to prevent overwhelming your conversation context:\n\n* **Output warning threshold**: Claude Code displays a warning when any MCP tool output exceeds 10,000 tokens\n* **Configurable limit**: you can adjust the maximum allowed MCP output tokens using the `MAX_MCP_OUTPUT_TOKENS` environment variable\n* **Default limit**: the default maximum is 25,000 tokens\n* **Scope**: the environment variable applies to tools that don't declare their own limit. Tools that set [`anthropic/maxResultSizeChars`](#raise-the-limit-for-a-specific-tool) use that value instead for text content, regardless of what `MAX_MCP_OUTPUT_TOKENS` is set to. Tools that return image data are still subject to `MAX_MCP_OUTPUT_TOKENS`\n\nTo increase the limit for tools that produce large outputs:\n\n```bash theme={null}\nexport MAX_MCP_OUTPUT_TOKENS=50000\nclaude\n```\n\nThis is particularly useful when working with MCP servers that:\n\n* Query large datasets or databases\n* Generate detailed reports or documentation\n* Process extensive log files or debugging information\n\n### Raise the limit for a specific tool\n\nIf you're building an MCP server, you can allow individual tools to return results larger than the default persist-to-disk threshold by setting `_meta[\"anthropic/maxResultSizeChars\"]` in the tool's `tools/list` response entry. Claude Code raises that tool's threshold to the annotated value, up to a hard ceiling of 500,000 characters.\n\nThis is useful for tools that return inherently large but necessary outputs, such as database schemas or full file trees. Without the annotation, results that exceed the default threshold are persisted to disk and replaced with a file reference in the conversation.\n\n```json theme={null}\n{\n  \"name\": \"get_schema\",\n  \"description\": \"Returns the full database schema\",\n  \"_meta\": {\n    \"anthropic/maxResultSizeChars\": 200000\n  }\n}\n```\n\nThe annotation applies independently of `MAX_MCP_OUTPUT_TOKENS` for text content, so users don't need to raise the environment variable for tools that declare it. Tools that return image data are still subject to the token limit.\n\n<Warning>\n  If you frequently encounter output warnings with specific MCP servers you don't control, consider increasing the `MAX_MCP_OUTPUT_TOKENS` limit. You can also ask the server author to add the `anthropic/maxResultSizeChars` annotation or to paginate their responses. The annotation has no effect on tools that return image content; for those, raising `MAX_MCP_OUTPUT_TOKENS` is the only option.\n</Warning>\n\n## Tool input schemas with a root-level combinator\n\nSome MCP servers declare a tool's input schema as a JSON Schema union, with `anyOf`, `oneOf`, or `allOf` at the top level of the schema. The Claude API doesn't accept those keywords at the schema root. It does accept combinators nested inside `properties`, which Claude Code sends unchanged.\n\nAs of Claude Code v2.1.195, tools with a root-level combinator stay available. Before sending the tool to the API, Claude Code flattens the schema into a single object and prepends a sentence to the tool's description that tells Claude which parameter groups belong together:\n\n* `allOf`: properties from every branch are merged, and each branch's `required` list still applies\n* `anyOf` and `oneOf`: properties from every branch are merged, and each branch's `required` list is described in the tool description instead of enforced by the schema\n\nYour server receives whichever arguments Claude chose, so keep validating the combination server-side.\n\nWhen Claude Code can't produce a schema the API accepts, or on a deployment that doesn't receive the remote configuration that enables the rewrite, such as an offline machine, it skips that one tool, records the reason in the server's log, and leaves the server's other tools available. Versions earlier than v2.1.195 skip every tool whose input schema has a root-level `anyOf`, `oneOf`, or `allOf`.\n\n## Require approval for a specific tool\n\nIf you're building an MCP server, you can mark a tool as requiring explicit approval on every call by setting `_meta[\"anthropic/requiresUserInteraction\"]` to `true` in the tool's `tools/list` response entry. The value must be the JSON boolean `true`; any other value is ignored.\n\nClaude Code shows that tool's permission prompt on every call, even in `acceptEdits`, `auto`, and `bypassPermissions` [permission modes](/en/permissions#permission-modes), and doesn't offer a \"don't ask again\" option for it. [Allow rules](/en/permissions#permission-rule-syntax) that match the tool don't skip the prompt either. In `dontAsk` mode, which never prompts, Claude Code denies the call instead.\n\nThe prompt has to reach a person. In non-interactive mode with [`--permission-prompt-tool`](/en/cli-reference#cli-flags), an `allow` result from the prompt tool for a flagged tool is converted to a deny with the message `MCP tool requires user interaction; not supported via --permission-prompt-tool`. The Agent SDK's [`canUseTool` callback](/en/agent-sdk/permissions) does receive these calls and can approve them, because the SDK host is expected to show them to a user.\n\nUse this for tools whose permission prompt is itself the point, such as a consent or access-grant step where auto-approval would mean no human ever agreed. Other tools from the same server keep their normal permission behavior.\n\nThe following `tools/list` entry marks one tool as always requiring approval.\n\n```json theme={null}\n{\n  \"name\": \"grant_access\",\n  \"description\": \"Requests access to a protected resource\",\n  \"_meta\": {\n    \"anthropic/requiresUserInteraction\": true\n  }\n}\n```\n\nThe `anthropic/requiresUserInteraction` annotation requires Claude Code v2.1.199 or later. Earlier versions ignore it and apply the standard permission flow.\n\nWhen a session is connected to [Remote Control](/en/remote-control) or an SDK host, Claude Code marks the permission request as requiring user interaction, so the client shows the tool's permission prompt for you to answer instead of a one-tap approve action.\n\n## Respond to MCP elicitation requests\n\nMCP servers can request structured input from you mid-task using elicitation. When a server needs information it can't get on its own, Claude Code displays an interactive dialog and passes your response back to the server. No configuration is required on your side: elicitation dialogs appear automatically when a server requests them.\n\nServers can request input in two ways:\n\n* **Form mode**: Claude Code shows a dialog with form fields defined by the server (for example, a username and password prompt). Fill in the fields and submit.\n* **URL mode**: Claude Code opens a browser URL for authentication or approval. Complete the flow in the browser, then confirm in the CLI.\n\nTo auto-respond to elicitation requests without showing a dialog, use the [`Elicitation` hook](/en/hooks#elicitation).\n\nIf you're building an MCP server that uses elicitation, see the [MCP elicitation specification](https://modelcontextprotocol.io/docs/learn/client-concepts#elicitation) for protocol details and schema examples.\n\n## Use MCP resources\n\nMCP servers can expose resources that you can reference using @ mentions, similar to how you reference files.\n\n### Reference MCP resources\n\n<Steps>\n  <Step title=\"List available resources\">\n    Type `@` in your prompt to see available resources from all connected MCP servers. Resources appear alongside files in the autocomplete menu.\n  </Step>\n\n  <Step title=\"Reference a specific resource\">\n    Use the format `@server:protocol://resource/path` to reference a resource:\n\n    ```text theme={null}\n    Can you analyze @github:issue://123 and suggest a fix?\n    ```\n\n    ```text theme={null}\n    Please review the API documentation at @docs:file://api/authentication\n    ```\n  </Step>\n\n  <Step title=\"Multiple resource references\">\n    You can reference multiple resources in a single prompt:\n\n    ```text theme={null}\n    Compare @postgres:schema://users with @docs:file://database/user-model\n    ```\n  </Step>\n</Steps>\n\n<Tip>\n  Tips:\n\n  * Resources are automatically fetched and included as attachments when referenced\n  * Resource paths are fuzzy-searchable in the @ mention autocomplete\n  * Claude Code automatically provides tools to list and read MCP resources when servers support them\n  * Resources can contain any type of content that the MCP server provides (text, JSON, structured data, etc.)\n</Tip>\n\n## Scale with MCP tool search\n\nTool search keeps MCP context usage low by deferring tool definitions until Claude needs them. Only tool names and server instructions load at session start, so adding more MCP servers has minimal impact on your context window. Claude Code doesn't impose a fixed per-server tool cap; the practical limit is your context window budget.\n\n### How it works\n\nTool search is enabled by default. MCP tools are deferred rather than loaded into context upfront, and Claude uses a search tool to discover relevant ones when a task needs them. Only the tools Claude actually uses enter context. From your perspective, MCP tools work exactly as before.\n\nIf you prefer threshold-based loading, set `ENABLE_TOOL_SEARCH=auto` to load schemas upfront when they fit within 10% of the context window and defer only the overflow. See [Configure tool search](#configure-tool-search) for all options.\n\n### For MCP server authors\n\nIf you're building an MCP server, the server instructions field becomes more useful with tool search enabled. Server instructions help Claude understand when to search for your tools, similar to how [skills](/en/skills) work.\n\nAdd clear, descriptive server instructions that explain:\n\n* What category of tasks your tools handle\n* When Claude should search for your tools\n* Key capabilities your server provides\n\nClaude Code truncates tool descriptions and server instructions at 2KB each. Keep them concise to avoid truncation, and put critical details near the start.\n\n### Configure tool search\n\nTool search is enabled by default: MCP tools are deferred and discovered on demand. Claude Code disables it by default on Google Cloud's Agent Platform. It is also disabled when `ANTHROPIC_BASE_URL` points to a non-first-party host, since most proxies don't forward `tool_reference` blocks. Set `ENABLE_TOOL_SEARCH` explicitly to override either fallback.\n\nTool search requires a model that supports `tool_reference` blocks. Haiku models don't support it. On Google Cloud's Agent Platform, tool search is supported for Claude Sonnet 4.5 and later and Claude Opus 4.5 and later.\n\nControl tool search behavior with the `ENABLE_TOOL_SEARCH` environment variable:\n\n| Value    | Behavior                                                                                                                                                                                                                                                                 |\n| :------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| (unset)  | All MCP tools deferred and loaded on demand.

Every tool from that server then loads into context at session start regardless of the `ENABLE_TOOL_SEARCH` setting. Use this for a small number of tools that Claude needs on every turn, since each upfront tool consumes context that would otherwise be available for your conversation.\n\nThe following `.mcp.json` entry exempts one HTTP server while leaving other servers deferred:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"core-tools\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.example.com/mcp\",\n      \"alwaysLoad\": true\n    }\n  }\n}\n```\n\nThe `alwaysLoad` field is available on all server types and requires Claude Code v2.1.121 or later. An MCP server can also mark individual tools as always-loaded by including `\"anthropic/alwaysLoad\": true` in the tool's `_meta` object, which has the same effect for that tool only.\n\nSetting `alwaysLoad: true` also blocks startup until the server connects, capped at the standard 5-second connect timeout. This applies even though MCP startup is otherwise [non-blocking by default](/en/env-vars), since the tools must be present when the first prompt is built. Other servers continue to connect in the background.\n\n## Use MCP prompts as commands\n\nMCP servers can expose prompts that become available as commands in Claude Code.\n\n### Execute MCP prompts\n\n<Steps>\n  <Step title=\"Discover available prompts\">\n    Type `/` to see all available commands, including those from MCP servers. MCP prompts appear with the format `/mcp__servername__promptname`.\n  </Step>\n\n  <Step title=\"Execute a prompt without arguments\">\n    ```text theme={null}\n    /mcp__github__list_prs\n    ```\n  </Step>\n\n  <Step title=\"Execute a prompt with arguments\">\n    Many prompts accept arguments. Pass them space-separated after the command:\n\n    ```text theme={null}\n    /mcp__github__pr_review 456\n    ```\n\n    ```text theme={null}\n    /mcp__jira__create_issue \"Bug in login flow\" high\n    ```\n  </Step>\n</Steps>\n\n<Tip>\n  Tips:\n\n  * MCP prompts are dynamically discovered from connected servers\n  * Arguments are parsed based on the prompt's defined parameters\n  * Prompt results are injected directly into the conversation\n  * Server and prompt names are normalized, with spaces converted to underscores\n</Tip>\n\n## Managed MCP configuration\n\nFor organizations that need centralized control over which MCP servers users can connect to, see [Managed MCP configuration](/en/managed-mcp). It covers deploying a fixed server set with `managed-mcp.json`, restricting servers with `allowedMcpServers` and `deniedMcpServers`, and what users see when a server is blocked.\n","durationMs":723,"url":"https://code.claude.com/docs/en/mcp.md"},"sourceToolAssistantUUID":"abd464d9-50ad-403a-a300-c103bffd3659","userType":"external","entrypoint":"cli","cwd":"/Users/marcus.hinz/claude-projects/ai-control","sessionId":"f7704328-4eb4-4f0f-bf42-da68abab401d","version":"2.1.207","gitBranch":"main"}

These tools come from MCP servers, which run on your machine or as hosted services.\n\nThis guide walks you through connecting one MCP server end to end with the Claude Code CLI. By the end, you'll have a server connected and responding, know where its configuration lives on disk, and know how to fix the most common connection errors.\n\n<Note>\n  You can also add MCP servers from other surfaces, including the desktop app, VS Code, and the web. See [Connect from other surfaces](#connect-from-other-surfaces).\n</Note>\n\nFor every way to connect and configure MCP servers in Claude Code, see the [MCP reference](/en/mcp).\n\n## Before you begin\n\nMake sure you have:\n\n* [Claude Code installed](/en/quickstart) and authenticated\n* A terminal open in a project directory. Any directory works, including an empty one.\n\n## Add and verify a server\n\nThe example below connects to the [Claude Code documentation MCP server](https://code.claude.com/docs/mcp), a hosted server with full-text search over the Claude Code docs. It doesn't require authentication or any special configuration, so it works well as a first server to test the setup flow with.\n\nThe steps are the same for any server: add it, check the connection status, then use it in a session, with an optional cleanup step at the end. Some servers add a step, like a browser sign-in, shown in [Additional MCP server examples](#additional-mcp-server-examples). For more servers to connect, browse the [Anthropic Directory](/en/mcp#find-and-build-mcp-servers).\n\n<Steps>\n  <Step title=\"Add the MCP server\">\n    Register the server with Claude Code. Run this in your terminal, not inside a `claude` session: you're configuring the server before starting a conversation.\n\n    ```bash theme={null}\n    claude mcp add --transport http claude-code-docs https://code.claude.com/docs/mcp\n    ```\n\n    The parts of the command:\n\n    * `claude mcp add`: registers a server with Claude Code.\n    * `--transport http`: the server is hosted at a URL rather than run as a local process.\n    * `claude-code-docs`: a name you make up. Calling the same server `docs` would work identically. Claude Code uses whatever name you pick to label the server's tools in Claude's output and to refer to the server in commands like `claude mcp remove`.\n    * `https://code.claude.com/docs/mcp`: the URL where the server is hosted.\n\n    The command prints a confirmation like `Added HTTP MCP server claude-code-docs with URL: https://code.claude.com/docs/mcp to local config`. The `local config` part means the server is registered to you, in this project: if you start Claude Code in a different project, this server isn't active there. To register a server once for all your projects, add it at user scope, covered in [Change server scope](#change-server-scope).\n  </Step>\n\n  <Step title=\"Check the connection status\">\n    Confirm the server appears in your server list and check its status:\n\n    ```bash theme={null}\n    claude mcp list\n    ```\n\n    The server appears with a status indicator:\n\n    | Status                             | Meaning                                                                                                                                                                       |\n    | :--------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n    | `✓ Connected`                      | Ready to use.

Naming it here guarantees the demonstration goes through the new server rather than another tool, such as web fetch, that could answer the same question.\n    </Info>\n\n    The first time Claude calls the server, it asks for permission to use the new tool. Approve it to continue. The tool call in Claude's output is labeled with the server name, which is how you confirm the answer came from the MCP server rather than Claude's built-in knowledge.\n  </Step>\n\n  <Step title=\"Remove the server\">\n    This step is optional. When you're done experimenting, you can remove the server:\n\n    ```bash theme={null}\n    claude mcp remove claude-code-docs\n    ```\n\n    <Note>\n      Each connected server takes some space in [Claude's context window](/en/how-claude-code-works#the-context-window) because its tool names and server instructions load into every session. Removing servers you no longer use keeps that space free.\n    </Note>\n  </Step>\n</Steps>\n\n## Where servers are saved\n\nThe `claude mcp add` command writes the server's details to a configuration file. By default it registers the server at `local` scope: private to you, active only in the current project. Pass `--scope user` to register it once for all your projects, or `--scope project` to share it with teammates. [Change server scope](#change-server-scope) walks through both.\n\n<Note>\n  `claude mcp add` works the same in every shell, including PowerShell and Command Prompt. Inside a `claude` session, use the `/mcp` command to check and manage servers you've already added.\n</Note>\n\nThere are other ways to add a server, each covered later on this page:\n\n* [Add a local server](#add-a-local-server): run a program on your machine instead of connecting to a URL.\n* [Edit `.mcp.json` directly](#edit-mcp-json-directly): write the JSON entry yourself instead of using the command.\n* [Connect a server that requires sign-in](#connect-a-server-that-requires-sign-in): add a hosted server that needs a browser sign-in before its tools work.\n\n### Find your configuration on disk\n\nThe `claude mcp add` command writes the server to one of three scopes, stored across two files, depending on the `--scope` flag. You don't need to edit these files directly, but knowing where they are helps with debugging and version control.\n\n| Scope     | File                                                   | Available to                             |\n| :-------- | :----------------------------------------------------- | :--------------------------------------- |\n| `local`   | `~/.claude.json`, under the entry for this project     | Only you, only this project. The default |\n| `project` | `.mcp.json` in your project root                       | Everyone who clones the project          |\n| `user`    | `~/.claude.json`, under the top-level `mcpServers` key | Only you, all projects                   |\n\nOn Windows, `~/.claude.json` resolves to `%USERPROFILE%\\.claude.json`, typically `C:\\Users\\YourName\\.claude.json`. If you've set [`CLAUDE_CONFIG_DIR`](/en/env-vars), Claude Code reads `.claude.json` from inside that directory instead.\n\nRun `claude mcp get claude-code-docs` to see which scope holds a server's definition. For how the scopes interact when the same server is defined in more than one, see [MCP installation scopes](/en/mcp#mcp-installation-scopes).\n\n## Change server scope\n\nA server's scope is fixed when you add it, so changing scope means removing the entry and re-adding it at the new one. Both cases below start by removing the local entry from the first walkthrough, so the server has only one definition. If you already removed it at the end of that walkthrough, skip this command:\n\n```bash theme={null}\nclaude mcp remove claude-code-docs --scope local\n```\n\n### Use a server in all your projects\n\nRe-add the server at `user` scope to make it active in every project you open, still private to you:\n\n```bash theme={null}\nclaude mcp add --scope user --transport http claude-code-docs https://code.claude.com/docs/mcp\n```\n\n### Share a server with your team\n\nRe-add the server at `project` scope, which writes to `.mcp.json` in the project root:\n\n```bash theme={null}\nclaude mcp add --scope project --transport http claude-code-docs https://code.claude.com/docs/mcp\n```\n\nCommit `.mcp.json` to version control. Teammates who clone the repository and start Claude Code see a prompt to approve the server, then it connects for them too.\n\n## Additional MCP server examples\n\nThe first walkthrough used a hosted server that connects without any sign-in. The examples below cover the other two common shapes, with the same add, check, use flow.\n\n### Add a local server\n\nA local stdio server is a program Claude Code starts as a subprocess on your machine, rather than a service it reaches over a URL. Use one for tools that need access to local resources like a browser, your filesystem, or a database socket.\n\nThe [Playwright MCP server](https://github.com/microsoft/playwright-mcp) is a good one to try: it gives Claude a browser it can navigate, click, and read, and it needs no account. It runs through `npx`, so it requires [Node.js](https://nodejs.org/en/download) 18 or later.\n\n<Steps>\n  <Step title=\"Add the Playwright server\">\n    Register the server with the command Claude Code should run to start it:\n\n    ```bash theme={null}\n    claude mcp add playwright -- npx -y @playwright/mcp@latest\n    ```\n\n    This command differs from the hosted example in three ways:\n\n    * There's no `--transport` flag, because local servers use the default `stdio` transport.\n    * Everything after the `--` separator is the command Claude Code runs to start the server.\n    * `-y` tells `npx` to install the package without prompting.\n\n    Playwright drives whichever Chrome is already installed on your machine. To use a different browser, append `--browser` with the browser name, for example `--browser firefox`, after `@playwright/mcp@latest`.\n  </Step>\n\n  <Step title=\"Check the connection\">\n    The `Added` confirmation means the entry was saved, not that the command runs. Check the connection:\n\n    ```bash theme={null}\n    claude mcp list\n    ```\n\n    The first check can show `✗ Failed to connect` while `npx` downloads the package, so wait a moment and run it again.\n  </Step>\n\n  <Step title=\"Use the browser\">\n    Give Claude a task that needs the browser:\n\n    ```text theme={null}\n    Use playwright to open https://example.com and tell me the page title\n    ```\n\n    A browser window opens so you can watch it work, and the tool calls in Claude's output are labeled with the `playwright` server name and the action, like `browser_navigate`.\n\n    Try pointing it at your local dev server to check that a page still renders after a change, or have it walk through a bug report step by step.\n  </Step>\n</Steps>\n\n### Connect a server that requires sign-in\n\nHosted services like Sentry, Linear, and Notion run their MCP servers behind OAuth: you add the server's URL, then sign in through your browser.\n\nThe steps below use Sentry as the example. To connect a different service, substitute its URL, which you can find in the [Anthropic Directory](/en/mcp#find-and-build-mcp-servers) or the service's documentation.\n\n<Steps>\n  <Step title=\"Add the server\">\n    The `add` command is the same as for the docs server, with Sentry's URL:\n\n    ```bash theme={null}\n    claude mcp add --transport http sentry https://mcp.sentry.dev/mcp\n    ```\n\n    After adding, `claude mcp list` shows the server with `! Needs authentication`. That's expected: the next step completes the sign-in.\n  </Step>\n\n  <Step title=\"Authenticate in your browser\">\n    Start a Claude Code session and open the MCP panel:\n\n    ```text theme={null}\n    /mcp\n    ```\n\n    Select `sentry` from the list, press Enter, and choose `Authenticate`. Your browser opens to Sentry's sign-in page. Approve the connection there.\n\n    Back in Claude Code, the server's status changes to connected. If sign-in fails or the browser doesn't open, see [Troubleshooting](#troubleshooting).\n  </Step>\n\n  <Step title=\"Use the server\">\n    Ask Claude something that needs the service, like `What Sentry projects do I have access to?`, and look for tool calls labeled with the `sentry` server name in its output.\n  </Step>\n</Steps>\n\nServers that authenticate with a static token instead of OAuth take the token at add time with `--header \"Authorization: Bearer <token>\"`. See the [GitHub example](/en/mcp#example-connect-to-github-for-code-reviews) for a worked version.\n\n## Edit .mcp.json directly\n\nEvery file in the [scope table](#find-your-configuration-on-disk) uses the same JSON format for server entries. This section edits `.mcp.json`, the project-scope file. It's the one most worth writing by hand because it's checked into the repository, where it doubles as configuration-as-code for your team.\n\nCreate `.mcp.json` in your project root. The example below defines both servers from this guide, the hosted docs server reached over HTTP and the Playwright server as a local `stdio` process:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"claude-code-docs\": {\n      \"type\": \"http\",\n      \"url\": \"https://code.claude.com/docs/mcp\"\n    },\n    \"playwright\": {\n      \"type\": \"stdio\",\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@playwright/mcp@latest\"]\n    }\n  }\n}\n```\n\nThe fields differ by server type:\n\n* For HTTP servers, `url` is the endpoint Claude Code connects to.\n* For stdio servers, `command` and `args` are the program it runs.\n\nAfter saving the file, start a new Claude Code session in the project. Claude Code reads `.mcp.json` at startup.\n\nThe first time Claude Code sees a project-scoped server, it asks you to approve it. The prompt exists so a repository you clone can't launch processes on your machine without your consent. Approve the prompt, or run `/mcp` to approve later if you missed it.\n\nOnce you've approved, run `/mcp` and check that the servers show as connected. If one shows an error instead, see [Troubleshooting](#troubleshooting).\n\n## Connect from other surfaces\n\nThis guide uses the `claude mcp` CLI commands, but every Claude Code surface can connect to MCP servers:\n\n* **Claude Code desktop app**: add servers through the [Connectors UI](/en/desktop#connect-external-tools).\n* **Claude Desktop chat app**: a separate app from Claude Code. To copy servers from its `claude_desktop_config.json` into the CLI, run `claude mcp add-from-claude-desktop` on macOS or WSL.\n* **VS Code**: see [Connect to external tools with MCP](/en/vs-code#connect-to-external-tools-with-mcp).\n* **Claude Code on the web**: reads `.mcp.json` from your repository. See [Edit .mcp.json directly](#edit-mcp-json-directly).\n* **Claude.ai**: connectors you add at [claude.ai/customize/connectors](https://claude.ai/customize/connectors) load automatically in the CLI when you sign in with that account. See [Use MCP servers from Claude.ai](/en/mcp#use-mcp-servers-from-claude-ai).\n\n## Troubleshooting\n\nIf a server doesn't connect, check its status with `/mcp` inside a session or `claude mcp list` from your shell, then match the symptom below. The `/mcp` panel also lets you reconnect or authenticate without leaving the session.\n\n<AccordionGroup>\n  <Accordion title=\"/mcp shows No MCP servers configured\">\n    Claude Code didn't find any servers for the current directory. The most common causes:\n\n    * You ran `claude mcp add` from a different project. Local-scoped servers are tied to the project where you added them: the repository root, or the exact directory if you weren't in a git repository. Re-add the server from the project you're in now, or add it with `--scope user` so it isn't tied to a project.\n    * You edited a configuration file at the wrong path. The correct files are `~/.claude.json` and `<project>/.mcp.json`. Claude Code doesn't read paths such as `~/.claude/.mcp.json`, `~/.claude/config/mcp.json`, `~/.claude/mcp.json`, or `%APPDATA%\\Claude\\mcp.json`. For user-scoped servers, run `claude mcp add --scope user`, which writes to the `mcpServers` key in `~/.claude.json`; for project-scoped servers, edit `.mcp.json` at the project root.\n  </Accordion>\n\n  <Accordion title=\"Status shows Failed to connect or Connection error\">\n    Both statuses mean the server didn't start or the URL didn't respond. They can also appear for HTTP servers that expect a token rather than the browser sign-in covered in [Connect a server that requires sign-in](#connect-a-server-that-requires-sign-in).\n\n    As of v2.1.191, an HTTP server that returns `404 Not Found` shows `MCP endpoint not found at <url>. Check the URL in your MCP config.` when you select the server in `/mcp`, with the URL Claude Code tried. Earlier versions show a generic `Error POSTing to endpoint` message without the URL. Compare the URL to the server's documented MCP endpoint path, then run `claude mcp remove <name>` and re-add with the correct URL.\n\n    For HTTP servers, confirm the URL is reachable from your machine:\n\n    ```bash theme={null}\n    curl -I https://mcp.sentry.dev/mcp\n    ```\n\n    In PowerShell, use `curl.exe` instead of `curl` so the request goes to the real curl binary rather than the `Invoke-WebRequest` alias.\n\n    The response tells you which kind of problem you have:\n\n    * A `404` or `405`: the server is up. Many MCP endpoints answer only POST requests, so this still confirms the URL is reachable from your machine.\n    * A `401` or `403`: the server is up and you need to authenticate. Use the browser sign-in in [Connect a server that requires sign-in](#connect-a-server-that-requires-sign-in), or for servers that take a token instead, like GitHub's, pass it with `--header \"Authorization: Bearer <token>\"` on the `claude mcp add` command.\n    * No response at all: check the URL and your network.\n\n    For stdio servers, run the configured command directly in your terminal to see the underlying error. For the Playwright server from this guide, run:\n\n    ```bash theme={null}\n    npx -y @playwright/mcp@latest\n    ```\n\n    What happens next tells you where the problem is:\n\n    * The command starts and waits for input: the server itself works. Run `claude mcp get <name>` and confirm the command shown there matches what you just ran. If the command shown differs from what you typed, you likely omitted the `--` separator before the server command. Remove the server and re-add it with `--` in place. If you wrote `.mcp.json` by hand, check its syntax and location.\n    * The command errors: the message names what's missing, such as Node.js or a browser.\n  </Accordion>\n\n  <Accordion title=\"Connection timed out at startup\">\n    The server took longer than the default 30-second startup timeout. A stdio server's first run can be slow while `npx` downloads the package. Increase the limit with the [`MCP_TIMEOUT`](/en/env-vars) environment variable, in milliseconds:\n\n    ```bash theme={null}\n    MCP_TIMEOUT=60000 claude\n    ```\n\n    In PowerShell, set the variable before the command on the same line:\n\n    ```powershell theme={null}\n    $env:MCP_TIMEOUT = \"60000\"; claude\n    ```\n  </Accordion>\n\n  <Accordion title=\"Server already exists\">\n    You've already added a server with that name at the same scope. Either remove the existing entry first or choose a different name:\n\n    ```bash theme={null}\n    claude mcp remove claude-code-docs\n    ```\n\n    If the name exists at more than one scope, `remove` reports `exists in multiple scopes`. Pass `--scope` to choose which copy to delete, for example `claude mcp remove claude-code-docs --scope local`.\n  </Accordion>\n\n  <Accordion title=\"Server connects but no tools appear\">\n    Run `/mcp` inside a session and select the server to see its tool list. If the list is empty, the server started but didn't register any tools, which usually means it's missing a required environment variable such as an API key.\n\n    Pass the variable with `--env KEY=value` on `claude mcp add`, or in the `env` field of the server's `.mcp.json` entry. The server's documentation lists the variables it needs.\n  </Accordion>\n\n  <Accordion title=\"Changes to .mcp.json don't take effect\">\n    Claude Code reads `.mcp.json` at session start. Exit and restart the session after editing the file.\n\n    If your servers still don't appear, run `/mcp` and look for a parse warning. Claude Code skips malformed entries and shows the offending field there.\n\n    If you previously rejected the server when prompted, reset project approvals:\n\n    ```bash theme={null}\n    claude mcp reset-project-choices\n    ```\n  </Accordion>\n\n  <Accordion title=\"OAuth sign-in fails or browser doesn't open\">\n    Run `/mcp`, select the server, and choose `Authenticate` again. If the browser doesn't open automatically, copy the URL shown in the terminal and open it manually. See [Authenticate with remote MCP servers](/en/mcp#authenticate-with-remote-mcp-servers) for fixed callback ports and pre-configured credentials.\n  </Accordion>\n</AccordionGroup>\n\n## Next steps\n\nWith one server connected, explore the rest of what MCP enables:\n\n* [Find more MCP servers](/en/mcp#find-and-build-mcp-servers) in the Anthropic Directory\n* [Share servers with your team](/en/mcp#mcp-installation-scopes) using installation scopes\n* [Manage MCP access for an organization](/en/managed-mcp) with managed settings and policy controls\n* [Reference MCP resources](/en/mcp#use-mcp-resources) in prompts with @ mentions\n* [Run MCP prompts as commands](/en/mcp#use-mcp-prompts-as-commands) from the `/` menu\n* [Build your own server](https://modelcontextprotocol.io/quickstart/server) with the MCP SDK\n"}]},"uuid":"8896d88e-931e-4af8-876c-86ef6f1d1044","timestamp":"2026-07-11T10:31:55.340Z","toolUseResult":{"bytes":23226,"code":200,"codeText":"OK","result":"> ## Documentation Index\n> Fetch the complete documentation index at: https://code.claude.com/docs/llms.txt\n> Use this file to discover all available pages before exploring further.\n\n# Connect to MCP servers\n\n> Add an MCP server to Claude Code, verify the connection, and find the configuration on disk.\n\nThe [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) lets Claude Code use tools beyond its built-in set, such as searching an issue tracker, querying a database, or controlling a web browser. These tools come from MCP servers, which run on your machine or as hosted services.\n\nThis guide walks you through connecting one MCP server end to end with the Claude Code CLI. By the end, you'll have a server connected and responding, know where its configuration lives on disk, and know how to fix the most common connection errors.\n\n<Note>\n  You can also add MCP servers from other surfaces, including the desktop app, VS Code, and the web. See [Connect from other surfaces](#connect-from-other-surfaces).\n</Note>\n\nFor every way to connect and configure MCP servers in Claude Code, see the [MCP reference](/en/mcp).\n\n## Before you begin\n\nMake sure you have:\n\n* [Claude Code installed](/en/quickstart) and authenticated\n* A terminal open in a project directory. Any directory works, including an empty one.\n\n## Add and verify a server\n\nThe example below connects to the [Claude Code documentation MCP server](https://code.claude.com/docs/mcp), a hosted server with full-text search over the Claude Code docs. It doesn't require authentication or any special configuration, so it works well as a first server to test the setup flow with.\n\nThe steps are the same for any server: add it, check the connection status, then use it in a session, with an optional cleanup step at the end. Some servers add a step, like a browser sign-in, shown in [Additional MCP server examples](#additional-mcp-server-examples). For more servers to connect, browse the [Anthropic Directory](/en/mcp#find-and-build-mcp-servers).\n\n<Steps>\n  <Step title=\"Add the MCP server\">\n    Register the server with Claude Code. Run this in your terminal, not inside a `claude` session: you're configuring the server before starting a conversation.\n\n    ```bash theme={null}\n    claude mcp add --transport http claude-code-docs https://code.claude.com/docs/mcp\n    ```\n\n    The parts of the command:\n\n    * `claude mcp add`: registers a server with Claude Code.\n    * `--transport http`: the server is hosted at a URL rather than run as a local process.\n    * `claude-code-docs`: a name you make up. Calling the same server `docs` would work identically. Claude Code uses whatever name you pick to label the server's tools in Claude's output and to refer to the server in commands like `claude mcp remove`.\n    * `https://code.claude.com/docs/mcp`: the URL where the server is hosted.\n\n    The command prints a confirmation like `Added HTTP MCP server claude-code-docs with URL: https://code.claude.com/docs/mcp to local config`. The `local config` part means the server is registered to you, in this project: if you start Claude Code in a different project, this server isn't active there. To register a server once for all your projects, add it at user scope, covered in [Change server scope](#change-server-scope).\n  </Step>\n\n  <Step title=\"Check the connection status\">\n    Confirm the server appears in your server list and check its status:\n\n    ```bash theme={null}\n    claude mcp list\n    ```\n\n    The server appears with a status indicator:\n\n    | Status                             | Meaning                                                                                                                                                                       |\n    | :--------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n    | `✓ Connected`                      | Ready to use.

Naming it here guarantees the demonstration goes through the new server rather than another tool, such as web fetch, that could answer the same question.\n    </Info>\n\n    The first time Claude calls the server, it asks for permission to use the new tool. Approve it to continue. The tool call in Claude's output is labeled with the server name, which is how you confirm the answer came from the MCP server rather than Claude's built-in knowledge.\n  </Step>\n\n  <Step title=\"Remove the server\">\n    This step is optional. When you're done experimenting, you can remove the server:\n\n    ```bash theme={null}\n    claude mcp remove claude-code-docs\n    ```\n\n    <Note>\n      Each connected server takes some space in [Claude's context window](/en/how-claude-code-works#the-context-window) because its tool names and server instructions load into every session. Removing servers you no longer use keeps that space free.\n    </Note>\n  </Step>\n</Steps>\n\n## Where servers are saved\n\nThe `claude mcp add` command writes the server's details to a configuration file. By default it registers the server at `local` scope: private to you, active only in the current project. Pass `--scope user` to register it once for all your projects, or `--scope project` to share it with teammates. [Change server scope](#change-server-scope) walks through both.\n\n<Note>\n  `claude mcp add` works the same in every shell, including PowerShell and Command Prompt. Inside a `claude` session, use the `/mcp` command to check and manage servers you've already added.\n</Note>\n\nThere are other ways to add a server, each covered later on this page:\n\n* [Add a local server](#add-a-local-server): run a program on your machine instead of connecting to a URL.\n* [Edit `.mcp.json` directly](#edit-mcp-json-directly): write the JSON entry yourself instead of using the command.\n* [Connect a server that requires sign-in](#connect-a-server-that-requires-sign-in): add a hosted server that needs a browser sign-in before its tools work.\n\n### Find your configuration on disk\n\nThe `claude mcp add` command writes the server to one of three scopes, stored across two files, depending on the `--scope` flag. You don't need to edit these files directly, but knowing where they are helps with debugging and version control.\n\n| Scope     | File                                                   | Available to                             |\n| :-------- | :----------------------------------------------------- | :--------------------------------------- |\n| `local`   | `~/.claude.json`, under the entry for this project     | Only you, only this project. The default |\n| `project` | `.mcp.json` in your project root                       | Everyone who clones the project          |\n| `user`    | `~/.claude.json`, under the top-level `mcpServers` key | Only you, all projects                   |\n\nOn Windows, `~/.claude.json` resolves to `%USERPROFILE%\\.claude.json`, typically `C:\\Users\\YourName\\.claude.json`. If you've set [`CLAUDE_CONFIG_DIR`](/en/env-vars), Claude Code reads `.claude.json` from inside that directory instead.\n\nRun `claude mcp get claude-code-docs` to see which scope holds a server's definition. For how the scopes interact when the same server is defined in more than one, see [MCP installation scopes](/en/mcp#mcp-installation-scopes).\n\n## Change server scope\n\nA server's scope is fixed when you add it, so changing scope means removing the entry and re-adding it at the new one. Both cases below start by removing the local entry from the first walkthrough, so the server has only one definition. If you already removed it at the end of that walkthrough, skip this command:\n\n```bash theme={null}\nclaude mcp remove claude-code-docs --scope local\n```\n\n### Use a server in all your projects\n\nRe-add the server at `user` scope to make it active in every project you open, still private to you:\n\n```bash theme={null}\nclaude mcp add --scope user --transport http claude-code-docs https://code.claude.com/docs/mcp\n```\n\n### Share a server with your team\n\nRe-add the server at `project` scope, which writes to `.mcp.json` in the project root:\n\n```bash theme={null}\nclaude mcp add --scope project --transport http claude-code-docs https://code.claude.com/docs/mcp\n```\n\nCommit `.mcp.json` to version control. Teammates who clone the repository and start Claude Code see a prompt to approve the server, then it connects for them too.\n\n## Additional MCP server examples\n\nThe first walkthrough used a hosted server that connects without any sign-in. The examples below cover the other two common shapes, with the same add, check, use flow.\n\n### Add a local server\n\nA local stdio server is a program Claude Code starts as a subprocess on your machine, rather than a service it reaches over a URL. Use one for tools that need access to local resources like a browser, your filesystem, or a database socket.\n\nThe [Playwright MCP server](https://github.com/microsoft/playwright-mcp) is a good one to try: it gives Claude a browser it can navigate, click, and read, and it needs no account. It runs through `npx`, so it requires [Node.js](https://nodejs.org/en/download) 18 or later.\n\n<Steps>\n  <Step title=\"Add the Playwright server\">\n    Register the server with the command Claude Code should run to start it:\n\n    ```bash theme={null}\n    claude mcp add playwright -- npx -y @playwright/mcp@latest\n    ```\n\n    This command differs from the hosted example in three ways:\n\n    * There's no `--transport` flag, because local servers use the default `stdio` transport.\n    * Everything after the `--` separator is the command Claude Code runs to start the server.\n    * `-y` tells `npx` to install the package without prompting.\n\n    Playwright drives whichever Chrome is already installed on your machine. To use a different browser, append `--browser` with the browser name, for example `--browser firefox`, after `@playwright/mcp@latest`.\n  </Step>\n\n  <Step title=\"Check the connection\">\n    The `Added` confirmation means the entry was saved, not that the command runs. Check the connection:\n\n    ```bash theme={null}\n    claude mcp list\n    ```\n\n    The first check can show `✗ Failed to connect` while `npx` downloads the package, so wait a moment and run it again.\n  </Step>\n\n  <Step title=\"Use the browser\">\n    Give Claude a task that needs the browser:\n\n    ```text theme={null}\n    Use playwright to open https://example.com and tell me the page title\n    ```\n\n    A browser window opens so you can watch it work, and the tool calls in Claude's output are labeled with the `playwright` server name and the action, like `browser_navigate`.\n\n    Try pointing it at your local dev server to check that a page still renders after a change, or have it walk through a bug report step by step.\n  </Step>\n</Steps>\n\n### Connect a server that requires sign-in\n\nHosted services like Sentry, Linear, and Notion run their MCP servers behind OAuth: you add the server's URL, then sign in through your browser.\n\nThe steps below use Sentry as the example. To connect a different service, substitute its URL, which you can find in the [Anthropic Directory](/en/mcp#find-and-build-mcp-servers) or the service's documentation.\n\n<Steps>\n  <Step title=\"Add the server\">\n    The `add` command is the same as for the docs server, with Sentry's URL:\n\n    ```bash theme={null}\n    claude mcp add --transport http sentry https://mcp.sentry.dev/mcp\n    ```\n\n    After adding, `claude mcp list` shows the server with `! Needs authentication`. That's expected: the next step completes the sign-in.\n  </Step>\n\n  <Step title=\"Authenticate in your browser\">\n    Start a Claude Code session and open the MCP panel:\n\n    ```text theme={null}\n    /mcp\n    ```\n\n    Select `sentry` from the list, press Enter, and choose `Authenticate`. Your browser opens to Sentry's sign-in page. Approve the connection there.\n\n    Back in Claude Code, the server's status changes to connected. If sign-in fails or the browser doesn't open, see [Troubleshooting](#troubleshooting).\n  </Step>\n\n  <Step title=\"Use the server\">\n    Ask Claude something that needs the service, like `What Sentry projects do I have access to?`, and look for tool calls labeled with the `sentry` server name in its output.\n  </Step>\n</Steps>\n\nServers that authenticate with a static token instead of OAuth take the token at add time with `--header \"Authorization: Bearer <token>\"`. See the [GitHub example](/en/mcp#example-connect-to-github-for-code-reviews) for a worked version.\n\n## Edit .mcp.json directly\n\nEvery file in the [scope table](#find-your-configuration-on-disk) uses the same JSON format for server entries. This section edits `.mcp.json`, the project-scope file. It's the one most worth writing by hand because it's checked into the repository, where it doubles as configuration-as-code for your team.\n\nCreate `.mcp.json` in your project root. The example below defines both servers from this guide, the hosted docs server reached over HTTP and the Playwright server as a local `stdio` process:\n\n```json theme={null}\n{\n  \"mcpServers\": {\n    \"claude-code-docs\": {\n      \"type\": \"http\",\n      \"url\": \"https://code.claude.com/docs/mcp\"\n    },\n    \"playwright\": {\n      \"type\": \"stdio\",\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@playwright/mcp@latest\"]\n    }\n  }\n}\n```\n\nThe fields differ by server type:\n\n* For HTTP servers, `url` is the endpoint Claude Code connects to.\n* For stdio servers, `command` and `args` are the program it runs.\n\nAfter saving the file, start a new Claude Code session in the project. Claude Code reads `.mcp.json` at startup.\n\nThe first time Claude Code sees a project-scoped server, it asks you to approve it. The prompt exists so a repository you clone can't launch processes on your machine without your consent. Approve the prompt, or run `/mcp` to approve later if you missed it.\n\nOnce you've approved, run `/mcp` and check that the servers show as connected. If one shows an error instead, see [Troubleshooting](#troubleshooting).\n\n## Connect from other surfaces\n\nThis guide uses the `claude mcp` CLI commands, but every Claude Code surface can connect to MCP servers:\n\n* **Claude Code desktop app**: add servers through the [Connectors UI](/en/desktop#connect-external-tools).\n* **Claude Desktop chat app**: a separate app from Claude Code. To copy servers from its `claude_desktop_config.json` into the CLI, run `claude mcp add-from-claude-desktop` on macOS or WSL.\n* **VS Code**: see [Connect to external tools with MCP](/en/vs-code#connect-to-external-tools-with-mcp).\n* **Claude Code on the web**: reads `.mcp.json` from your repository. See [Edit .mcp.json directly](#edit-mcp-json-directly).\n* **Claude.ai**: connectors you add at [claude.ai/customize/connectors](https://claude.ai/customize/connectors) load automatically in the CLI when you sign in with that account. See [Use MCP servers from Claude.ai](/en/mcp#use-mcp-servers-from-claude-ai).\n\n## Troubleshooting\n\nIf a server doesn't connect, check its status with `/mcp` inside a session or `claude mcp list` from your shell, then match the symptom below. The `/mcp` panel also lets you reconnect or authenticate without leaving the session.\n\n<AccordionGroup>\n  <Accordion title=\"/mcp shows No MCP servers configured\">\n    Claude Code didn't find any servers for the current directory. The most common causes:\n\n    * You ran `claude mcp add` from a different project. Local-scoped servers are tied to the project where you added them: the repository root, or the exact directory if you weren't in a git repository. Re-add the server from the project you're in now, or add it with `--scope user` so it isn't tied to a project.\n    * You edited a configuration file at the wrong path. The correct files are `~/.claude.json` and `<project>/.mcp.json`. Claude Code doesn't read paths such as `~/.claude/.mcp.json`, `~/.claude/config/mcp.json`, `~/.claude/mcp.json`, or `%APPDATA%\\Claude\\mcp.json`. For user-scoped servers, run `claude mcp add --scope user`, which writes to the `mcpServers` key in `~/.claude.json`; for project-scoped servers, edit `.mcp.json` at the project root.\n  </Accordion>\n\n  <Accordion title=\"Status shows Failed to connect or Connection error\">\n    Both statuses mean the server didn't start or the URL didn't respond. They can also appear for HTTP servers that expect a token rather than the browser sign-in covered in [Connect a server that requires sign-in](#connect-a-server-that-requires-sign-in).\n\n    As of v2.1.191, an HTTP server that returns `404 Not Found` shows `MCP endpoint not found at <url>. Check the URL in your MCP config.` when you select the server in `/mcp`, with the URL Claude Code tried. Earlier versions show a generic `Error POSTing to endpoint` message without the URL. Compare the URL to the server's documented MCP endpoint path, then run `claude mcp remove <name>` and re-add with the correct URL.\n\n    For HTTP servers, confirm the URL is reachable from your machine:\n\n    ```bash theme={null}\n    curl -I https://mcp.sentry.dev/mcp\n    ```\n\n    In PowerShell, use `curl.exe` instead of `curl` so the request goes to the real curl binary rather than the `Invoke-WebRequest` alias.\n\n    The response tells you which kind of problem you have:\n\n    * A `404` or `405`: the server is up. Many MCP endpoints answer only POST requests, so this still confirms the URL is reachable from your machine.\n    * A `401` or `403`: the server is up and you need to authenticate. Use the browser sign-in in [Connect a server that requires sign-in](#connect-a-server-that-requires-sign-in), or for servers that take a token instead, like GitHub's, pass it with `--header \"Authorization: Bearer <token>\"` on the `claude mcp add` command.\n    * No response at all: check the URL and your network.\n\n    For stdio servers, run the configured command directly in your terminal to see the underlying error. For the Playwright server from this guide, run:\n\n    ```bash theme={null}\n    npx -y @playwright/mcp@latest\n    ```\n\n    What happens next tells you where the problem is:\n\n    * The command starts and waits for input: the server itself works. Run `claude mcp get <name>` and confirm the command shown there matches what you just ran. If the command shown differs from what you typed, you likely omitted the `--` separator before the server command. Remove the server and re-add it with `--` in place. If you wrote `.mcp.json` by hand, check its syntax and location.\n    * The command errors: the message names what's missing, such as Node.js or a browser.\n  </Accordion>\n\n  <Accordion title=\"Connection timed out at startup\">\n    The server took longer than the default 30-second startup timeout. A stdio server's first run can be slow while `npx` downloads the package. Increase the limit with the [`MCP_TIMEOUT`](/en/env-vars) environment variable, in milliseconds:\n\n    ```bash theme={null}\n    MCP_TIMEOUT=60000 claude\n    ```\n\n    In PowerShell, set the variable before the command on the same line:\n\n    ```powershell theme={null}\n    $env:MCP_TIMEOUT = \"60000\"; claude\n    ```\n  </Accordion>\n\n  <Accordion title=\"Server already exists\">\n    You've already added a server with that name at the same scope. Either remove the existing entry first or choose a different name:\n\n    ```bash theme={null}\n    claude mcp remove claude-code-docs\n    ```\n\n    If the name exists at more than one scope, `remove` reports `exists in multiple scopes`. Pass `--scope` to choose which copy to delete, for example `claude mcp remove claude-code-docs --scope local`.\n  </Accordion>\n\n  <Accordion title=\"Server connects but no tools appear\">\n    Run `/mcp` inside a session and select the server to see its tool list. If the list is empty, the server started but didn't register any tools, which usually means it's missing a required environment variable such as an API key.\n\n    Pass the variable with `--env KEY=value` on `claude mcp add`, or in the `env` field of the server's `.mcp.json` entry. The server's documentation lists the variables it needs.\n  </Accordion>\n\n  <Accordion title=\"Changes to .mcp.json don't take effect\">\n    Claude Code reads `.mcp.json` at session start. Exit and restart the session after editing the file.\n\n    If your servers still don't appear, run `/mcp` and look for a parse warning. Claude Code skips malformed entries and shows the offending field there.\n\n    If you previously rejected the server when prompted, reset project approvals:\n\n    ```bash theme={null}\n    claude mcp reset-project-choices\n    ```\n  </Accordion>\n\n  <Accordion title=\"OAuth sign-in fails or browser doesn't open\">\n    Run `/mcp`, select the server, and choose `Authenticate` again. If the browser doesn't open automatically, copy the URL shown in the terminal and open it manually. See [Authenticate with remote MCP servers](/en/mcp#authenticate-with-remote-mcp-servers) for fixed callback ports and pre-configured credentials.\n  </Accordion>\n</AccordionGroup>\n\n## Next steps\n\nWith one server connected, explore the rest of what MCP enables:\n\n* [Find more MCP servers](/en/mcp#find-and-build-mcp-servers) in the Anthropic Directory\n* [Share servers with your team](/en/mcp#mcp-installation-scopes) using installation scopes\n* [Manage MCP access for an organization](/en/managed-mcp) with managed settings and policy controls\n* [Reference MCP resources](/en/mcp#use-mcp-resources) in prompts with @ mentions\n* [Run MCP prompts as commands](/en/mcp#use-mcp-prompts-as-commands) from the `/` menu\n* [Build your own server](https://modelcontextprotocol.io/quickstart/server) with the MCP SDK\n","durationMs":473,"url":"https://code.claude.com/docs/en/mcp-quickstart.md"},"sourceToolAssistantUUID":"87896937-2a5f-424b-98b8-4cdaf87d5f38","userType":"external","entrypoint":"cli","cwd":"/Users/marcus.hinz/claude-projects/ai-control","sessionId":"f7704328-4eb4-4f0f-bf42-da68abab401d","version":"2.1.207","gitBranch":"main"}

The documentation I've fetched doesn't explain:\n\n1. **Whether the TUI label uses the server key, tool name, or tool title field** — The GitHub issue #37542 confirms that Claude Code currently does **NOT** render the MCP tool `title` field in the TUI, despite the MCP spec supporting it. This is a tracked feature request still pending implementation.\n\n2. **Whether \"aicontrol\" gets prettified to \"ai control\"** — I found no documentation about server name prettification in the current version (2.1.207).\n\n3. **Permission string format after renaming** — The format appears to be `mcp__<server-key>__<tool-name>` based on search results, but I cannot confirm how hyphens or spaces in the server key are handled in the permission string.\n\nSince this is a highly specific implementation detail not covered in the official docs, I'd recommend:\n\n- **Verify experimentally** with your current setup: rename `aicontrol` to `text-panel` or similar in `.claude.json`, restart a session, then:\n  - Check what the TUI displays for the call label\n  - Check what permission string is generated when prompted\n  \n- **File a feature request** if you want tool `title` field support (issue #37542 is still open)\n\n- **Check the GitHub releases/issues** directly at https://github.com/anthropics/claude-code for any recent discussion on server display naming\n\nI cannot give you the exact concrete change with confidence because the behavior isn't documented and may vary by version.\n\nSources:\n- [Claude Code Changelog](https://code.claude.com/docs/en/changelog.md)\n- [MCP Tool `title` Field Rendering Feature Request](https://github.com/anthropics/claude-code/issues/37542)\n- [MCP Quick Start Guide](https://code.claude.com/docs/en/mcp-quickstart.md)"}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":8,"cache_creation_input_tokens":606,"cache_read_input_tokens":27318,"output_tokens":508,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":606},"inference_geo":"not_available","iterations":[{"input_tokens":8,"output_tokens":508,"cache_read_input_tokens":27318,"cache_creation_input_tokens":606,"cache_creation":{"ephemeral_5m_input_tokens":606,"ephemeral_1h_input_tokens":0},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Ccv7psDsuf1QzuhNVk6nA","attributionAgent":"claude-code-guide","type":"assistant","uuid":"a2f89cf6-cdfa-4b64-8a16-a5bf1344a6a8","timestamp":"2026-07-11T10:33:09.337Z","userType":"external","entrypoint":"cli","cwd":"/Users/marcus.hinz/claude-projects/ai-control","sessionId":"f7704328-4eb4-4f0f-bf42-da68abab401d","version":"2.1.207","gitBranch":"main"}
