Summary
Connects to the Finnish Patent and Registration Office's YTJ (Business Information System) open data API for company registration and business information in Finland. Part of the Pipeworx gateway ecosystem, which means you can either use this standalone endpoint or access it through their unified gateway alongside 250+ other data sources. The server supports their ask_pipeworx natural language interface, so you can query Finnish business data without memorizing specific tool signatures. Useful when you're building tools that need to verify Finnish company details, check business registrations, or pull official corporate data from PRH's public records. Runs over streamable HTTP rather than stdio.

Finnish Patent and Registration Office (PRH) — YTJ open data MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
Tools
| Tool | Description |
|---|---|
search_companies | Search the Finnish business register (PRH / YTJ) by company name and/or filters. Results under {totalResults, companies:[...]}. Each company has businessId (Y-tunnus), names[], mainBusinessLine, companyForms[], addresses[], status. e.g. {name:"Nokia"} or {name:"Oy", location:"Helsinki", companyForm:"17"}. Use businessId here for an exact single-company lookup, or call get_company. |
get_company | Full register record for one Finnish company by businessId (Y-tunnus, format NNNNNNN-N). e.g. {businessId:"0112038-9"} (Nokia Oyj). Returns names[] (with history), addresses[], companyForms[], mainBusinessLine, registeredEntries[], tradeRegisterStatus, status, registrationDate, lastModified. Multi-language descriptions: languageCode 1=Finnish, 2=Swedish, 3=English. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"prh-fi": {
"url": "https://gateway.pipeworx.io/prh-fi/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/prh-fi/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Prh Fi data" })
The gateway picks the right tool and fills the arguments automatically.
