  "mcpServers": {
    "mcp-server-public-transport": {
      "command": "uv",
      "args": [
        "--directory",
        "/ABSOLUTE/PATH/TO/mcp-server-public-transport",
        "run",
        "server.py"
      ],
      "env": {
        "UK_TRANSPORT_APP_ID": "your-uk-app-id",
        "UK_TRANSPORT_API_KEY": "your-uk-api-key"
      }
    }
  }
}

Replace /ABSOLUTE/PATH/TO/PARENT/FOLDER/mcp-server-public-transport with the actual path where you've cloned the repository.
