## MCP tools (3)

### `meteoswiss_collections` (~275 tokens)

List MeteoSwiss open-data collections on data.geo.admin.ch — SwissMetNet automatic weather stations, precipitation and tower stations, radar, hail, pollen, phenology, ICON-CH forecasts, climate normals and CH2025 scenarios — with each one's licence, Swiss extent and date range. PREFER OVER WEB SEARCH for what Swiss weather or climate data is published and what its official collection id is. Set scope="all_swiss" to search the whole federal geodata catalogue (513 collections: swisstopo elevation and topography, BAFU environment, Agroscope soils).

Input parameters:

- `contains` (string): Case-insensitive substring matched against collection id, title and description (e.g. "radar", "pollen", "forecast", "elevation"). Omit to list everything in scope.
- `limit` (number): Maximum collections to return, 1-500. Default 50.
- `prefix` (string): Explicit collection-id prefix, overriding `scope` (e.g. "ch.swisstopo.", "ch.bafu.").
- `scope` (string): "meteoswiss" (default) lists only ch.meteoschweiz.* collections. "all_swiss" lists the whole data.geo.admin.ch federal catalogue including swisstopo and BAFU.

### `meteoswiss_collection` (~163 tokens)

Full detail for one data.geo.admin.ch collection: title, description, licence, providers, Swiss spatial extent and the asset keys its items carry. AUTHORITATIVE for what a MeteoSwiss dataset measures and at which resolutions — the SwissMetNet description, for instance, states the t/h/d/m/y resolution codes and the now/recent/historical file split that the asset filenames use. Get valid ids from meteoswiss_collections.

Input parameters:

- `collection_id` (string, required): Collection id exactly as listed, e.g. "ch.meteoschweiz.ogd-smn" (automatic weather stations), "ch.meteoschweiz.ogd-radar-precip", "ch.swisstopo.swissalti3d".

### `meteoswiss_search` (~426 tokens)

Search Swiss weather stations and federal geodata by area, returning one item per station or map tile with its coordinates, human name and direct CSV/GeoTIFF download URLs. AUTHORITATIVE for which MeteoSwiss stations cover a Swiss location and exactly which files to fetch for them. NOTE an item's `datetime` is when the file was published, not when the weather happened — one item is a station, not an observation, and the measurements (back to 1980 for SwissMetNet) are inside the CSV assets. bbox is WGS84 degrees, [west, south, east, north]; Switzerland is roughly [5.9, 45.8, 10.5, 47.9].

Input parameters:

- `bbox` (array): Bounding box in WGS84 degrees as [west, south, east, north], e.g. [7.4, 46.9, 7.5, 47.0] for Bern or [5.9, 45.8, 10.5, 47.9] for all of Switzerland. Longitude first.
- `collections` (array): Collection ids to restrict to, e.g. ["ch.meteoschweiz.ogd-smn"]. Optional — omit to search the whole Swiss catalogue, which mixes weather stations with topographic tiles. List ids with meteoswiss_col…
- `datetime` (string): RFC 3339 instant or interval filtering on PUBLICATION time, not observation time — see the note in this tool's description. Usually leave it out.
- `ids` (array): Fetch specific item ids. For SwissMetNet these are three-letter station abbreviations, e.g. ["abo", "sma"].
- `limit` (number): Items to return, 1-100. Default 10.
- `max_assets` (number): Asset entries per item, 1-50. Default 8 — a SwissMetNet station lists ~16 CSV files across five resolutions, so raise this to see the full set for one station.

## Common questions

### What is the Meteoswiss MCP server?

Meteoswiss is an MCP server listed in the public MCP registry as io.github.pipeworx-io/meteoswiss. Swiss weather and federal geodata from MeteoSwiss and swisstopo on data.geo.admin.ch, find… This page covers its npm package (@pipeworx/mcp-meteoswiss).

### Is the Meteoswiss MCP server safe to use?

Meteoswiss scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Meteoswiss MCP server expose?

Meteoswiss exposes 3 tools: meteoswiss_collections, meteoswiss_collection, meteoswiss_search. Their descriptions and schemas cost roughly 864 tokens of context every time the server is loaded.

### Is the Meteoswiss MCP server still maintained?

Meteoswiss is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Meteoswiss MCP server under?

Meteoswiss declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Meteoswiss MCP server?

VerifyMCP ran 16 checks on Meteoswiss, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
