BAFU environmental data, NABEL air quality, hydrology
Swiss MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. BAFU environmental data, NABEL air quality, hydrology.
The server covers four thematic clusters: air quality (NABEL), hydrology, natural hazards, and the BAFU open data catalogue. Each cluster maps to a group of purpose-built tools that translate raw agency data into clean JSON responses.
The server ships on PyPI as swiss-environment-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once Swiss is connected, these are the calls the assistant has available:
env_nabel_stations — List all 16 NABEL monitoring stations with location type and cantonenv_nabel_current — Current air quality data for a station (NO₂, O₃, PM10, PM2.5, SO₂, CO)env_air_limits_check — Compare a measurement against Swiss LRV limits and WHO 2021 guidelinesenv_hydro_stations — Filter hydrological gauging stations by water body (canton filter unavailable — see notes)env_hydro_current — Current water level, flow rate and temperature at a stationenv_hydro_history — Historical hourly values (up to 30 days) with download links ⚠️env_flood_warnings — Active flood warnings filtered by danger level (nationwide — canton filter not applied)env_bathing_water — Bathing water quality (E.coli, enterococci) per bathing site — multi-year time seriesenv_hazard_overview — Router: points to the dedicated live hazard tools + official portals (no network call — the aggregate naturgefahren.ch API was discontinued)env_hazard_regions — Router: maps a hazard type (flood/avalanche/wildfire/snow) to the right live tool + portal (no network call)env_wildfire_danger — Wildfire danger index by canton and regionenv_snow_stations — List automatic SLF/IMIS snow measurement stations (by canton)Plenty of monitoring and observability servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Swiss's toolset — env_nabel_stations, env_nabel_current, env_air_limits_check and 11 more — is a fair guide to whether it matches your workflow. It is maintained by malkreide; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
