{
  "mcpServers": {
    "warm": {
      "httpUrl": "https://app.warm.io/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_WARM_API_KEY"
      }
    }
  }
}

Start Gemini CLI and run /mcp to check that Warm is connected.

Gemini CLI can't use Warm sign in yet, so it uses a Warm API key. A key gives your assistant read only access, but the key itself can reach the rest of the Warm API for your account. Keep it out of chats and screenshots.To disconnect Gemini CLI, delete its key in Settings, Export & API.

Cursor

    }
  }
