Api Key

Sourcegraph is a code intelligence platform for searching, understanding, and managing code across large-scale repositories. It helps developers find, review, and analyze code quickly, boosting productivity and collaboration.

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Sourcegraph account to Claude via Composio Connect, enabling it to show all languages used in repo backend-service, compare latest two commits in project web-ui, list all files under src/utils in repo app-core, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Sourcegraph to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Sourcegraph account

Back in Claude, ask it to connect to Sourcegraph or give it any Sourcegraph-related task.

For example, ask Claude to:

  • "Show all languages used in repo backend-service"
  • "Compare latest two commits in project web-ui"
  • "List all files under src/utils in repo app-core"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Sourcegraph account is ready to use.

What is the Sourcegraph Claude Connector, and what's possible with it?

The Sourcegraph MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sourcegraph account. It provides structured and secure access to your codebase, so your agent can perform actions like searching repositories, inspecting commits, fetching file contents, and analyzing code languages on your behalf.

  • Repository discovery and listing: Let your agent list all repositories in your Sourcegraph instance, making it easy to navigate and select codebases for deeper analysis.
  • Commit inspection and comparison: Have the agent fetch details about specific commits or compare two commits to see file-level changes and diffs in any repository.
  • File content retrieval: Ask your agent to fetch the raw contents of any file in your codebase—no cloning or manual browsing required.
  • Repository file and language enumeration: Enable the agent to list all files, directories, and programming languages used in a given repository for a comprehensive code overview.
  • User identity and permissions checks: Let your agent verify the authenticated user or check site settings permissions before performing sensitive actions.

Troubleshooting

1. Why does Claude not use the Composio connector for Sourcegraph?

The connector can show as connected, but Claude must use it in each Sourcegraph conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Sourcegraph again.

2. Why does Claude show an MCP server error before Sourcegraph connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Sourcegraph.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Sourcegraph.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Sourcegraph authorization link not work?

The Composio connector is one server. Your Sourcegraph account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Sourcegraph connection.
  • Composio creates a fresh Sourcegraph authorization link.
  • Open that link in your browser and finish the Sourcegraph sign-in.

4. Why do Sourcegraph actions fail after they worked before?

The Sourcegraph connection can expire or lose permission.

  • Ask Claude to inspect the Sourcegraph connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Sourcegraph account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Sourcegraph.
  • If the action still fails with a permission error, check that the connected account has that permission in Sourcegraph itself.

5. How do I switch to a different Sourcegraph account?

Claude can manage the Sourcegraph connection for you.

  • Ask Claude to disconnect or delete the current Sourcegraph account.
  • Ask Claude to connect Sourcegraph again.
  • Open the new Composio authorization link for Sourcegraph.
  • Sign in with the other Sourcegraph account in the browser.
  • After the account connects, ask Claude to retry the Sourcegraph task.

6. Why is my Sourcegraph connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Sourcegraph connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Sourcegraph tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Sourcegraph.

FAQ

Frequently asked questions

With a standalone Sourcegraph MCP server, the agents and LLMs can only access a fixed set of Sourcegraph tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Sourcegraph and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Sourcegraph tools.

Yes, absolutely. You can configure which Sourcegraph scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Sourcegraph data and credentials are handled as safely as possible.
