Kosis Kr

@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 1882+ 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 1882+ 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":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-kosis-kr

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

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.
