Give GitHub Copilot in VS Code its own inbox

In your workspace’s .vscode/mcp.json. The URL is all it needs.

{
  "servers": {
    "pidgeon": {
      "type": "http",
      "url": "https://pidgeon.ai/api/mcp"
    }
  }
}

When the server first starts, VS Code sends you to Pidgeon to sign in. You choose what it can do — read, read and send, or full access — and which address it reaches, or every address if you own the account. That becomes an API key under Developers → API keys → Connected apps, and Disconnect there ends it.

https://pidgeon.ai/api/mcp

For an agent with nobody there to sign in. VS Code prompts for the key the first time and keeps it in its secret storage, so nothing is written to the file.

      "type": "http",

    }
  }
