Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

  const out = execSync(`unzip -p "${zipPath}" "${csvName}"`);
Builds a database query by concatenation src/lib/checkout-measures.ts:87
    ${['basket', 'locale', 'entry'].map(key => `UNION ALL SELECT '${key}', ${key}, ${countsSql} FROM scoped GROUP BY ${key}`).join('\n')}`)
Reads files and sends them to the network src/lib/crm-source.ts:27
    for (const entry of await readdir(root, { withFileTypes: true })) {
Sends data to a third-party sink src/lib/workflow-watch.ts:149
    response = await fetcher(`https://api.telegram.org/bot${config.token}/sendMessage`, {

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

tariff
tariff_lookup
Look up the Swiss customs tariff (TARES). An 8-digit Swiss tariff number (dots allowed) returns the full line: designations in FR/DE/IT/EN, MFN duty, preferential regimes, restrictions and customs relief codes. A 2- to 7-digit HS prefix (for example the international HS6 code) lists the Swiss 8-digit lines under it. Every result carries an unofficial-copy notice that the agent must show to the end user.
tariff_semantic_search
FREE TRIAL without a key: 20 calls per day per IP address in total for tariff_semantic_search, classify_text and finma_search. Each answer states the trial calls left; check every result on the official tariff at xtares.admin.ch before use. Find Swiss customs tariff (TARES) lines from a description of the goods in French, German, Italian or English, or from a tariff number. Each line is indexed with its official hierarchy (heading, intermediate texts, 8-digit line) in the four languages; ranking puts shared official words first and uses meaning (pinned multilingual mpnet model) as a tie-breaker and for synonyms. Returns the 8-digit code, its official path, a relative score, the TARES data version and the index provenance. Always inlines a non-official disclaimer.
classify
classify_text
FREE TRIAL without a key: 20 calls per day per IP address in total for tariff_semantic_search, classify_text and finma_search. Each answer states the trial calls left; check every result on the NOGA publications of the Federal Statistical Office before use. Classify a business activity description (French, German, Italian or English) into the closest NOGA 2025 subclasses (6 digits) with their class (the NACE 2.1 class), official hierarchy and a similarity score, using a pinned multilingual mpnet model. A NOGA code as text lists its subclasses. Each answer states the index provenance and the classification reference version; combine with cross_walk for NACE, ISIC or NOGA 2008.
company
company_check
Look up a Swiss company by its UID (CHE-xxx.xxx.xxx): commercial register data (LINDAS), FINMA register entries and LEI records (GLEIF), each fact with its source and, when known, the date it was read, plus exact cross-checks between sources and checks of the registered address against the official localities and streets directories (swisstopo, when published). No score. When available, the commercial register status (active, in liquidation or deleted, with the deletion date) is read from Zefix (OFRC). FOSC publications, SECO sanctions and officers are not covered.
cross
cross_walk
Find correspondences between NOGA 2008, NOGA 2025, NACE 2.0, NACE 2.1 and ISIC 4 activity codes (Swiss, EU and UN classifications). Returns the exact or approximate relation, its sources and the documented path. Never chains two non-exact relations; a non-exact correspondence needs expert validation.
finma
finma_search
FREE TRIAL without a key: 20 calls per day per IP address in total for tariff_semantic_search, classify_text and finma_search. Each answer states the trial calls left; check every result on the official FINMA register before use. Search the FINMA register by entity name, tolerant of case, accents, legal forms (AG, SA, Sàrl, GmbH, Ltd), ae/oe/ue spellings and one or two typos per word. Results are ranked exact, word start, whole word, prefix, substring, all words in any order, then typo guesses, each labelled with match_type. Set include_warnings=true to also search the FINMA warnings list. Each answer states the FINMA data version.
kyc
kyc_check
Search the FINMA register of supervised institutions and the FINMA warnings list by name (case- and accent-insensitive). Returns the closest top_k authorised entities and warning entries (exact name, then whole word, then substring; all words in any order as a fallback) with the total number of matches. Only an identical name is reported as a FINMA warning-list match; a merely similar name is listed separately, to verify, and is never called a match. Use it for basic counterparty screening; no result is not a compliance certificate.

OpenSwissData — questions

Answers built from our own checks of this server.

What can OpenSwissData do?
It exposes 7 tools, read directly from the server on our last check. Among them: classify_text, company_check, cross_walk, finma_search, kyc_check, tariff_lookup and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is OpenSwissData working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 218 ms. The bar chart above shows every period we have measured.
Did OpenSwissData ever remove tools?
Yes. statent_lookup, entity_history, tariff_changelog are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect OpenSwissData?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does OpenSwissData need an API key?
No. OpenSwissData completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is OpenSwissData?
It answers our handshake in 218 ms on average, which is faster than 64% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use OpenSwissData?
The npm package @openswissdata/mcp was installed 65 times in the last week. Week over week that is +225%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is OpenSwissData open source?
The code is open source: it is published under the Apache-2.0 licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.openswissdata.com, which runs on its operator's own terms.
