Kosis Kr MCP Server

@pipeworx/kosis-kr

Korean national statistics (KOSIS) — browse, search and pull time series from Statistics Korea's official statistical database of ~100,000 tables covering population, prices, employment, trade and industry.

Part of Pipeworx — an MCP gateway connecting AI agents to 1865+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• kosis_stat_list({ parentListId, vwCd, _apiKey }) — walk the table directory one level at a time.
• kosis_search({ searchNm, orgId, startCount, resultCount, _apiKey }) — find tables by keyword; returns the orgId + tblId pair the data tool needs.
• kosis_stat_data({ orgId, tblId, itmId, objL1, objL2, prdSe, newEstPrdCnt, startPrdDe, endPrdDe, _apiKey }) — observations from one table.

Auth

Platform key (PLATFORM_KOSIS_KEY) with BYO override via ?_apiKey=. Free registration at https://kosis.kr/openapi/ — sign up, request OpenAPI access per service, key issued immediately (no manual approval step).

Data sources

• https://kosis.kr/openapi/statisticsList.do — table directory.
• https://kosis.kr/openapi/statisticsSearch.do — keyword search over tables.
• https://kosis.kr/openapi/Param/statisticsParameterData.do — observations.

Traps

• KOSIS reports an invalid or missing key as HTTP 200 with a body of {"err":"11","errMsg":"유효하지않은 인증KEY입니다."}. Every status-code check reads that as success. This pack inspects err on a 200 and raises.
• prdSe must match what the table actually publishes. Asking a monthly table for "Y" returns zero observations with no error.
• Korean-language search terms match far more tables than English ones.
• The success payload is unverified — no fleet key exists. Field names come from the published parameter guide; every tool also returns raw, so a caller with a real key gets the untouched payload if a name here is stale.

Quick Start

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

{
  "mcpServers": {
    "kosis-kr": {
      "url": "https://gateway.pipeworx.io/kosis-kr/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/kosis-kr/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 1865+ 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

This pack takes your own API key (_apiKey) — we don't front one for it, so there's no curl here that would run without it. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/kosis_stat_list. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-kosis-kr 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/kosis-kr/mcp endpoint shown above. It needs network access; there is no offline mode.

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

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 Kosis Kr data" })

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