Sourcebot MCP server

The Sourcebot MCP Server connects AI tools to your Sourcebot deployment. This gives your agents the ability to search, read files, resolve references & definitions, and more across all of your code hosted on Sourcebot.

only available in a paid plan. Please activate a license key to use this feature.

Use cases

Context for local agents: Plug the MCP into coding agents like Cursor, Claude Code, or Copilot to give them context across your entire codebase, not just the open workspace.
Building autonomous AI agents: Use Sourcebot as a code context layer for multi-agent systems that review PRs, auto-fix bugs, and answer questions across the company.

Getting Started

Sourcebot MCP uses a Streamable HTTP transport hosted at the /api/mcp route. Two authorization mechanisms are supported:

OAuth (preferred): MCP clients that support OAuth 2.0 will automatically handle the authorization flow and issue a short lived access token. No API key or manual token management required. Only available with a paid subscription.
API key: Any MCP client can authorize using a Sourcebot API key passed as a Authorization: Bearer <key> header. Create one in Settings → API Keys.

You can read more about the options in the authorization section.

If anonymous access is enabled on your Sourcebot instance, no OAuth token or API key is required. You can connect directly to the MCP endpoint without any authorization.

The examples below add the MCP server and connect it to Sourcebot’s public deployment at app.sourcebot.dev. Replace the URL with your own Sourcebot deployment as needed.

Authorization

The Sourcebot MCP server supports two authorization methods, OAuth and API keys. If anonymous access is enabled on your instance, no authorization is required. Regardless of which method you use, all MCP requests are scoped to the associated Sourcebot user and inherit the user’s role and permissions. When permission syncing is configured, this includes repository permissions - the MCP server will only surface results from repositories the user has access to.

OAuth 2.0

only available in a paid plan. Please activate a license key to use this feature.

Sourcebot implements an OAuth 2.0 authorization server with support for dynamic client registration (RFC 7591). This means MCP clients can register themselves automatically without any manual setup. Just point your client at the MCP endpoint and it will handle the full authorization flow, prompting you to log in and approve access in your browser the first time you connect. No API key or manual token management is required. Once authorized, Sourcebot issues a short-lived access token (valid for 1 hour) and a refresh token (valid for 90 days). The MCP client handles token refresh automatically, so you stay connected without needing to re-authorize.

API Key (Bearer token)

API keys provide a simpler alternative to OAuth that works with any MCP client. Each key is scoped to the user who created it and inherits their permissions. To create one, navigate to Settings → API Keys and click Create API Key. Pass the key as an Authorization: Bearer <key> header when connecting to the MCP server.

You see branches created or deleted on the code host only after Sourcebot next syncs the repository. For each branch, you get its name, head commit SHA, latest commit time, isDefault (whether it is the repository’s default branch), and isIndexed (whether code search can search that branch).

Lists the available language models configured on the Sourcebot instance. Use this to discover which models can be specified when calling ask_codebase. Parameters: This tool takes no parameters.

`ask_codebase`

Ask a natural language question about the codebase. This tool uses an AI agent to autonomously search code, read files, and find symbol references/definitions to answer your question. Returns a detailed answer in markdown format with code references, plus a link to view the full research session in the Sourcebot web UI. Parameters:

Name	Required	Description
`query`	yes	The query to ask about the codebase.
`repos`	no	The repositories that are accessible to the agent during the chat. If not provided, all repositories are accessible.
`languageModel`	no	The language model to use for answering the question. Object with `provider` and `model`. If not provided, defaults to the first model in the config. Use `list_language_models` to see available options.
`visibility`	no	The visibility of the chat session (`'PRIVATE'` or `'PUBLIC'`). Defaults to `PRIVATE` for authenticated users and `PUBLIC` for anonymous users. Set to `PUBLIC` to make the chat viewable by anyone with the link (useful in shared environments like Slack).

`create_skill`

You can create an agent skill: a reusable set of instructions you invoke in Ask Sourcebot as a /<slug> slash command, or that the agent loads automatically when your request matches its description. The skill is personal to you and enabled immediately. The result includes a link to the skill in Settings → Skills. You need an authenticated user (API key or OAuth) and the Ask Sourcebot feature. Anonymous sessions and repository-scoped access tokens cannot use this tool. Parameters:

Name	Required	Description
`name`	yes	Display name for the skill (1-80 characters).
`slug`	yes	Slash command for the skill, without the leading `/`. Lowercase letters, numbers, and hyphens; at most 64 characters. Must be unique among the user’s skills.
`description`	yes	When to use the skill (1-500 characters). Used by the agent to auto-load the skill.
`instructions`	yes	Markdown instructions the agent follows when the skill is invoked (1-20,000 characters).

`update_skill`

You can edit an existing skill in place. Fields you omit keep their current values. You can edit your personal skills, and shared skills only if you created them and they are enabled. Skills synced from a repository file are rejected; edit those in Settings → Skills. This tool never enables or disables a skill, and never moves it between the personal and shared catalogs. You need an authenticated user (API key or OAuth) and the Ask Sourcebot feature. Anonymous sessions and repository-scoped access tokens cannot use this tool. Parameters:

Name	Required	Description
`slug`	yes	Current slash command of the skill to update, without the leading `/`.
`scope`	yes	Which catalog the skill lives in: `personal` or `shared`.
`name`	no	New display name (1-80 characters).
`newSlug`	no	New slash command, without the leading `/`. Lowercase letters, numbers, and hyphens; at most 64 characters.
`description`	no	New description of when to use the skill (1-500 characters).
`instructions`	no	New markdown instructions (1-20,000 characters).

`list_skills`

You can list the skills visible to you: your personal skills plus your organization’s shared catalog. Each row includes slug and scope (the pair update_skill needs), enabled, isSynced (linked to a repository file), canEdit (whether update_skill can edit it), and, on shared rows, adopted. Skill instructions are never included. You need an authenticated user (API key or OAuth) and the Ask Sourcebot feature. Anonymous sessions and repository-scoped access tokens cannot use this tool. Parameters:

Name	Required	Description
`scope`	no	Filter to one catalog: `personal` or `shared`. Omit to list both.
