## MCP tools (5)

### `search_datasets` (~164 tokens)

Search the opendata.swiss catalogue (CKAN package_search). Returns matching Swiss federal/cantonal datasets. Titles/descriptions are multilingual {de,fr,it,en}; each result is annotated with English-preferred `title_en`/`notes_en`.

Input parameters:

- `fq` (string): Solr filter query, e.g. "organization:bundesamt-fur-statistik-bfs" or "groups:health".
- `query` (string, required): Free-text query, e.g. "energy", "population", "ÖV".
- `rows` (number): 1-1000 (default 25).
- `sort` (string): e.g. "metadata_modified desc", "score desc".
- `start` (number): 0-based offset for paging.

### `dataset_details` (~84 tokens)

Full metadata for one dataset (CKAN package_show) including its resources/distributions with download URLs. Use a dataset `name` (slug) or id from search_datasets. There is no datastore, so fetch `resources[].download_url`/`url` for the underlying data.

Input parameters:

- `id` (string, required): Dataset slug or id, e.g. "energie1".

### `list_organizations` (~66 tokens)

List publishing organizations (federal offices, cantons, etc.). Multilingual titles flattened to `title_en`. Use a returned `name` as `organization:<name>` in search_datasets `fq`.

Input parameters:

- `limit` (number): 1-1000 (default 100).

### `list_groups` (~71 tokens)

List thematic categories (CKAN groups / themes, e.g. health, education, energy). Multilingual titles flattened to `title_en`. Use a returned `name` as `groups:<name>` in search_datasets `fq`.

Input parameters:

- `limit` (number): 1-1000 (default 100).

### `list_tags` (~57 tokens)

List or search keyword tags used across the catalogue (CKAN tag_list). Useful for discovering facet values.

Input parameters:

- `limit` (number): Cap returned tags client-side (default 200).
- `query` (string): Optional substring to filter tags.

## Common questions

### What is the Opendata Swiss MCP server?

Opendata Swiss is an MCP server listed in the public MCP registry as io.github.pipeworx-io/opendata-swiss. opendata.swiss MCP, Switzerland's federal open-data portal (CKAN catalogue). This page covers its npm package (@pipeworx/mcp-opendata-swiss).

### Is the Opendata Swiss MCP server safe to use?

Opendata Swiss scores 85 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 Opendata Swiss MCP server expose?

Opendata Swiss exposes 5 tools: search_datasets, dataset_details, list_organizations, list_groups, list_tags. Their descriptions and schemas cost roughly 442 tokens of context every time the server is loaded.

### Is the Opendata Swiss MCP server still maintained?

Opendata Swiss 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 Opendata Swiss MCP server under?

Opendata Swiss 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 Opendata Swiss MCP server?

VerifyMCP ran 16 checks on Opendata Swiss, 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.
