Golemio

An MCP server that exposes Prague's Golemio open data API to AI assistants. Query public transit departures, air quality, parking availability, and more.

Installation

Get an API key from https://api.golemio.cz/api-keys/

Add to your MCP configuration (e.g., ~/.mcp.json):

{
  "mcpServers": {
    "golemio": {
      "command": "uvx",
      "args": ["golemio-mcp"],
      "env": {
        "GOLEMIO_API_KEY": "your-api-key"
      }
    }
  }
}

Requires uv to be installed.

NixOS users: uvx won't work due to dynamic linking. See Development for NixOS-specific configuration.

Local MCP configuration

To run from a local clone instead of PyPI:

{
  "mcpServers": {
    "golemio": {
      "command": "uv",
      "args": ["--directory", "/path/to/golemio-mcp-server", "run", "golemio-mcp"],
      "env": {
        "GOLEMIO_API_KEY": "your-api-key"
      }
    }
  }
}

On NixOS, use system Python to avoid dynamic linking issues:

{
  "mcpServers": {
    "golemio": {
      "command": "nix-shell",
      "args": [
        "-p", "uv",
        "--run", "UV_PYTHON=/run/current-system/sw/bin/python3 uv --directory /path/to/golemio-mcp-server run golemio-mcp"
      ],
      "env": {
        "GOLEMIO_API_KEY": "your-api-key"
      }
    }
  }
}
