mcp-server-public-transport

An MCP Server providing real-time public transport data across Europe.

About

mcp-server-public-transport is a Model Context Protocol (MCP)-compatible local server that provides access to public transport data across Europe. Currently, it integrates APIs from UK, Switzerland, Norway, Belgium, Berlin/Brandenburg and Portugal (Lisbon + Porto), allowing you to retrieve train connections, live departures, and bus locations.

Feature Implementation Status

Supported Countries

Features by Country

Portugal coverage is scoped to the Lisbon and Porto metro areas (Metro Lisboa, Carris, Carris Metropolitana, CP suburban; Metro do Porto, STCP) via Transitous, a free MOTIS instance over ingested GTFS feeds. No API key required.

Attribution (Transitous)

Lisbon/Porto data is served by Transitous, a volunteer-run, best-effort service (limited hosting, no availability or accuracy guarantees). Keep the Transitous attribution visible when showing this data to users; underlying feeds, including OpenStreetMap, are listed at transitous.org/sources.

Follow the Transitous usage policy: modest request volume, an identifying User-Agent, non-commercial / open-source use only.

Setup

Environment Variables

Set the following environment variables:

UK_TRANSPORT_APP_ID=your_uk_app_id
UK_TRANSPORT_API_KEY=your_uk_api_key

Usage with Claude Desktop

Add to your claude_desktop_config.json`:

{
  "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.

Note: You may need to put the full path to the uv executable in the command field. You can get this by running which uv on MacOS/Linux or where uv on Windows.
