Wraps the MeteoSwiss open data STAC API so Claude can query Swiss weather stations, radar composites, forecasts, and climate grids on demand. Exposes tools to load current conditions, historical observations, and gridded datasets like ICON forecasts or precipitation radar. Under the hood it converts CSV station data to Parquet with Polars and opens NetCDF/GRIB2/ODIM files as xarray datasets. Reach for this when you need Swiss weather context in a conversation, whether that's daily temperature in Bern, a week of precipitation data, or checking forecast models. The same Python package powers CLI downloads and optional Delta ingestion into Databricks, but the MCP layer gives you live MeteoSwiss queries without leaving the chat.
