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.

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.

Development

Setting up Development Environment

Running Tests

The project uses pytest for testing with the following commands available:

# Run all tests
make test

Code Quality

# Run linting
make lint

# Run code formatting
make format

Continuous Integration

The project includes a GitHub Actions workflow (.github/workflows/test.yml) that automatically:

• Runs tests on Python 3.10, 3.11, and 3.12
• Executes linting checks using ruff
• Runs on every push and pull request to main branch

The CI pipeline ensures code quality and compatibility across supported Python versions before any changes are merged.
