MeteoSwiss MCP Server

eins78/meteoswiss-llm-tools

Connects Claude to MeteoSwiss Open Government Data, the same feed behind Switzerland's official weather app. Exposes six tools: multi-day forecasts for 6000+ Swiss locations by postal code or name, real-time measurements from 160 automatic stations updated every 10 minutes, station search by canton or GPS coordinates, pollen monitoring from 15 stations, and MeteoSwiss website search and content retrieval. No API key required. Available as a hosted service at meteoswiss-mcp.ars.is or self-hosted via Docker. Handles queries in German, French, Italian, and English. Useful when you need authoritative Swiss weather data without scraping or dealing with authentication.
