Api Key

Devin MCP is an AI-powered integration for accessing and analyzing GitHub repositories and documentation. It enables secure, automated codebase intelligence, even for private repos.

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 Devin account to Claude via Composio Connect, enabling it to summarize codebase structure for devin-ai/devin, list all open pull requests for a repo, generate documentation summary for private repository, 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 Devin 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 Devin account

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

For example, ask Claude to:

  • "Summarize codebase structure for devin-ai/devin"
  • "List all open pull requests for a repo"
  • "Generate documentation summary for private repository"

It will prompt you to authenticate and authorize access.

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

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

The Devin MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Devin account. It provides structured and secure access so your agent can perform Devin operations on your behalf.

Troubleshooting

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

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

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

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

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

  • 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 Devin.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Devin authorization link not work?

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

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

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

The Devin connection can expire or lose permission.

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

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

Claude can manage the Devin connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Devin 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 Devin.

FAQ

Frequently asked questions

With a standalone Devin MCP server, the agents and LLMs can only access a fixed set of Devin tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Devin 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 Devin tools.

Yes, absolutely. You can configure which Devin 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 Devin data and credentials are handled as safely as possible.
