# Devin

> Connect Devin to Darwin Search and Act through a custom remote MCP server.

Add Darwin as a custom remote MCP server in Devin. This gives Devin the current Darwin tools without adding a repository credential or a Devin-specific Darwin endpoint.

<Steps>
  <Step title="Open the MCP settings">
    In Devin, open **Settings → Connections → MCP servers**, then choose **Add a custom MCP**.
  </Step>

  <Step title="Configure Darwin">
    Name the server `Darwin`, choose **HTTP**, and enter `https://mcp.darwin.so/mcp` as the server URL.
  </Step>

  <Step title="Authenticate">
    Choose **OAuth**, save the configuration, and use **Connect** to complete Darwin's browser authorization.
  </Step>

  <Step title="Test the tools">
    Run **Test listing tools**, then start a new session and ask Devin to perform a harmless Search.
  </Step>
</Steps>

Devin supports self-serve custom servers and can test their advertised tools before a session. Cognition documents no public third-party marketplace submission form.

Read [Devin's current MCP setup guide](https://docs.devin.ai/work-with-devin/mcp) for transport, access-scope, and OAuth behavior.

```text theme={null}
Search Darwin for a harmless public capability. Show the exact capability ID
and revision, then stop before starting an Action.
```

<Warning>
  Installing or authorizing Darwin does not pre-approve an Action. Darwin's current `availableActions` remains the
  authority for what Devin can do next.
</Warning>
