What is the Meteoswiss MCP server?

Meteoswiss MCP server exists for a simple reason — assistants are far more useful when they can act on Meteoswiss directly instead of describing what you should do. Swiss weather data for AI agents — MeteoSwiss open data exposed two ways: MCP server and agent skill.

What you get

Swiss weather data for AI assistants — powered by MeteoSwiss Open Government Data (OGD), the same data behind the MeteoSwiss app and website. Free, no API key required.

What the assistant can call

Once Meteoswiss is connected, these are the calls the assistant has available:

  • Multi — day forecasts** for ~6000 Swiss locations (postal codes, stations, place names)
  • Real — time measurements** from ~300 stations (~160 full weather + ~140 precipitation-only), updated every 10 minutes
  • meteoswissLocalForecast — Multi-day forecasts by postal code, station, or place name
  • meteoswissCurrentWeather — Real-time measurements (temperature, wind, humidity, pressure)
  • meteoswissStations — Search station network by name, canton, or coordinates
  • meteoswissPollenData — Pollen concentration data from monitoring stations
  • meteoswissClimateData — NBCN climate series — temperature, precipitation, sunshine, and climate indicators going back decades
  • search — Search MeteoSwiss website content (DE, FR, IT, EN)
  • fetch — Fetch full content from MeteoSwiss pages

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Choosing this one

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. Meteoswiss's toolset — Multi, Real, meteoswissLocalForecast and 6 more — is a fair guide to whether it matches your workflow. It is maintained by eins78; 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We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 9 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Meteoswiss.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the meteoswiss mcp server does with a few real requests.

Frequently asked questions
