Sk Rpo MCP Server

@pipeworx/sk-rpo

Slovakia's primary legal-entity register — search companies, sole traders and public bodies by name or IČO, then pull the full record (statutory bodies, stakeholders, equity, predecessors, change history) for one entity.

Part of Pipeworx — an MCP gateway connecting AI agents to 1866+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• rpo_search_entity(fullName?, identifier?, legalForm?, addressMunicipality?, addressStreet?, establishmentAfter?/Before?, terminationAfter?/Before?, onlyActive?, stakeholderCompanyName?, stakeholderPersonFamilyName?, statutoryBodyFamilyName?, limit?) — search for entities. Matching is a diacritics-insensitive substring match, not relevance-ranked, so a short or common query can return hundreds of hits; at least one filter is required. Returns each match's internal id, current/historical names, IČO, addresses and establishment/termination dates.
• rpo_entity_detail(id?, ico?, includeHistory?, includeOrganizationUnits?) — the full record for one entity: legal forms, address history, statutory bodies (directors/executives), stakeholders (owners/partners), equity and shares, predecessors (mergers/splits), statistical classification codes, and the source register (Obchodný register / Živnostenský register / etc.) with its registration number. Pass id from a prior search, or ico to resolve by IČO first.

Auth

Keyless. No registration, no API key.

Data sources

• Statistical Office of the Slovak Republic (ŠÚ SR), Register právnických osôb, podnikateľov a orgánov verejnej moci (RPO) — the national register of every legal entity, entrepreneur and public authority with a Slovak IČO. Published under a CC-BY 4.0 licence; every API response carries the licence text (this pack strips it from tool output and cites it here instead).

ORSR (orsr.sk, the Ministry of Justice's commercial register — adds share capital / partner / executive detail for commercially-registered entities) was evaluated as the secondary source for this build. It is an HTML site with no public API, so it is not wired in. RPO alone already returns statutory bodies, stakeholders, equity and shares for every entity this pack was tested against — re-evaluate ORSR only if a caller needs something RPO's API does not expose.

finstat.sk, a commercial Slovak company-data reseller, was ruled out as a candidate per the build task (it is not a primary register).

Quirks worth knowing

• Matching is substring, not fulltext-ranked. fullName=ESET returns 272 results (anything containing "eset" once diacritics are folded — e.g. "Rešeta" matches, since "š"→"s" makes "reseta" contain "eset") and the exact target may not be first. Use the fullest name string you have, or search by identifier (IČO) for a precise hit.
• Diacritics are folded, not required. "Zilinska" and "Žilinská" match the same records; you do not need to get the diacritics right.
• identifier requires 3+ characters to exact-match; shorter strings are not treated as fulltext and may return nothing.
• The upstream caps search results at 500 regardless of how many actually match; there is no documented pagination/offset parameter, so a query that hits the cap should be narrowed rather than paged.
• rpo_entity_detail takes the register's internal id, not the IČO, for its path parameter — GET /entity/{ico} 404s. Pass ico to this tool and it resolves to the internal id for you via an exact-identifier search first.
• The documented query-parameter names are not discoverable from the API itself — GET /search with no recognized parameter returns a generic {"message":"No parameters specified in search request"} for both "no params at all" and "params I don't recognize," and there is no swagger/docs endpoint served at api.statistics.sk. The confirmed parameter set (verified live): fullName, identifier, legalForm, legalStatus, addressMunicipality, addressStreet, establishmentAfter/Before, terminationAfter/Before, onlyActive, mainActivity, esa2010, sourceRegister, stakeholderType, stakeholderPersonGivenName/FamilyName, stakeholderCompanyName, statutoryBodyType, statutoryBodyGivenName/FamilyName, statutoryBodyCompanyName, and the orgUnits* equivalents of the organization-unit fields. This pack exposes the subset verified to return real matches during build (legalStatus and mainActivity returned zero results for every value tried and are left out pending real test values).

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "sk-rpo": {
      "url": "https://gateway.pipeworx.io/sk-rpo/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/sk-rpo/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 1866+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/rpo_search_entity \
  -H 'Content-Type: application/json' \
  -d '{"fullName":"ESET, spol","onlyActive":true}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/rpo_search_entity. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-sk-rpo is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/sk-rpo/mcp endpoint shown above. It needs network access; there is no offline mode.

{
  "mcpServers": {
    "sk-rpo": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-sk-rpo"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

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 Sk Rpo data" })

The gateway picks the right tool and fills the arguments automatically.
