It provides two tools: get_station_data for current weather observations from a specific DWD station, and get_nowcast_warnings for current nowcast weather warnings in Germany.

How do I find DWD station IDs?

Station IDs are required for get_station_data. The official DWD station list is available at their website. Common examples include 10381 (Berlin-Brandenburg), 10865 (Berlin-Tegel), 10147 (Hamburg), 10637 (Köln-Bonn), and 10870 (Munich).

After manual configuration, verify the server runs (node dwd-server.js), confirm the path in claude_desktop_config.json is correct, and restart Claude Desktop.

Does DWD MCP Server support data outside Germany?

No. The server is explicitly designed to access the Deutsche Wetterdienst API, which only covers German weather stations and warnings.
