Every answer traces to a named official source — SBB and PostBus for transport, MeteoSwiss, BAFU, swisstopo, ZEFIX, SLF, the SNB and the Federal Statistical Office. Load it whole only if you genuinely roam that widely; otherwise pass --modules or --preset so a commute question does not drag the parliament and earthquake tools along with it.
A single server fronting a long list of Swiss public data sources, each already public and unauthenticated, exposed as tools grouped into modules you can switch on individually.
- Transport: search stations, plan a journey between two points, and read live departures and arrivals, including stations near a coordinate
- Weather and hydrology: current conditions and history at MeteoSwiss stations, plus river and lake levels and temperatures from BAFU monitoring stations
- Geodata from swisstopo: geocode an address, reverse-geocode a coordinate, search place names and mountains, identify the data layers at a point, and get rooftop solar potential
- Companies: search the ZEFIX federal registry by name, canton or legal form, look one up in full, and find who is registered at an address
- Public and school holidays by canton, and a check on whether today is one
- Parliament: search bills, motions and interpellations, list members and their declared interests, get votes and speeches on an affair, session schedules, committee meetings, and cantonal parliaments across all 26 cantons
- Alerts and environment: SLF avalanche bulletins and warning regions, snow conditions and station measurements, NABEL air-quality stations with the Swiss legal limits, and hiking trail closures near a coordinate
- Everyday admin: postcode lookup and search, Swiss Post parcel tracking URLs, Zurich waste-collection calendars, and electricity tariffs by municipality with side-by-side comparison
- Numbers: population and Federal Statistical Office datasets, Swiss National Bank CHF exchange rates current and historical, the residential property price index and the consumer price index
- And the rest: SRF news headlines and keyword search, popular vote results, the federal dam registry, ASTRA traffic counts, and recent earthquakes from the Swiss Seismological Service
No account, no API key and no registration — every source behind it is Swiss open data. It runs over stdio: npx mcp-swiss, the Docker image vikramgorla/mcp-swiss, or the .mcpb bundle for one-click install in Claude Desktop. --modules and --preset trim what loads — the commuter preset keeps transport, weather and holidays at 14 tools and minimal keeps transport alone at 5 — and --list-modules and --list-presets show what is on offer.
One command — npx mcp-swiss
