What it can do

Common questions
Is OpenSwissData safe?
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: OPENSWISSDATA_API_KEY
Does it run on my computer or in the cloud?
Either way works: install it on your computer or connect to the cloud version.
Is it still maintained?
The GitHub repo last changed yesterday, and the latest version (0.3.2) reached the registry 5 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Ruflo, Context7, Metabase

@openswissdata/mcp
MCP server for Swiss federal reference data: the Swiss customs tariff (TARES), the FINMA register of supervised institutions and the FINMA warnings list, and NOGA / NACE / ISIC activity-code correspondences. Four tools work without any key or sign-up.
This package is a small STDIO bridge to the remote OpenSwissData MCP endpoint, for clients that only launch local processes. Clients that speak MCP over HTTP can connect directly to https://mcp.openswissdata.com/jsonrpc without it.
Free tools (no key)
Limit: 100 calls per hour per IP address.
| Tool | What it answers |
|---|---|
tariff_lookup | An 8-digit Swiss tariff number (dots allowed, e.g. 8471.3000) returns the full TARES line: designations in FR/DE/IT/EN, MFN duty, preferential regimes, restrictions, customs relief codes. A 2- to 7-digit HS prefix (e.g. the international HS6 code 847130) lists the Swiss 8-digit lines under it. |
kyc_check | Searches the FINMA register and the FINMA warnings list by entity name. |
company_check | A Swiss company by UID (CHE-xxx.xxx.xxx): commercial register, FINMA and LEI records, each fact with its source. |
cross_walk | Maps an activity code between NOGA 2008, NOGA 2025, NACE 2.0, NACE 2.1 and ISIC 4, with the relation type and its source. |
tariff_semantic_search, classify_text and finma_search are free to try without a key: 20 calls per day in total per IP address. tariff_changelog and entity_history need existing access rights; new paid subscriptions are closed at the moment. Buying a dataset file does not create an API key. statent_lookup has been withdrawn.
Setup
Claude Code, remote endpoint (no bridge needed):
claude mcp add --transport http openswissdata https://mcp.openswissdata.com/jsonrpc
Clients configured with mcpServers and a local process (Claude Desktop, Cline and others):
{
"mcpServers": { "openswissdata": { "command": "npx", "args": ["-y", "@openswissdata/mcp"] } } }
Tools and their schemas come from the server at each listing.
| Variable | Default | Use |
|---|---|---|
OPENSWISSDATA_API_KEY | none | Existing OAuth token, for the rights it carries |
OPENSWISSDATA_BASE_URL | https://mcp.openswissdata.com | Alternative server |
OPENSWISSDATA_TIMEOUT_MS | 30000 | Timeout, including reading the whole response |
Keep a key in the client's private configuration. Diagnostics go to stderr; stdout is reserved for the protocol. openswissdata-mcp --version and --help print the version and help.
Development
Node 22 is used for the checks. The runtime keeps its Node 18+ declaration; use a maintained version.
npm ci
npm run typecheck npm test npm run build npm pack --dry-run
The tests run a full MCP exchange with the official SDK and interrupt a response whose body stalls. A change in the repository does not publish a new npm version: check the registry separately before distribution.
The Dockerfile offers a local alternative: docker build -t openswissdata-mcp ., then docker run --rm -i openswissdata-mcp.
Limits
OpenSwissData is an unofficial copy. Keep the notices shown to the user. An approximate correspondence needs expert validation; a missing tariff value does not mean duty-free; no FINMA result is not a compliance certificate. Check the original sources (xtares.admin.ch, finma.ch, the Swiss Federal Statistical Office) before any decision.
