Security Report

6.2

Moderate6.2Moderate Risk

This is a well-constructed MCP server for accessing Statistics Finland's public StatFin database via the PxWeb API. Authentication is not required (as StatFin is public data), and the server implements proper input validation, error handling, and safe HTTP operations. The codebase is clean with no detected malicious patterns, hardcoded credentials, or dangerous operations. Permissions are appropriately scoped to the server's purpose (bundled data, network HTTP for API calls, file read for index). Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

@nor-data/statfin-mcp

MCP server for official statistics from Statistics Finland (Tilastokeskus) — the StatFin database, exposed through the PxWeb API. Search 3000+ tables, inspect their dimensions, and pull data as JSON-stat2. No API key required.

Part of the nor-data family of Nordic open-data MCP servers. Built on the same pattern as the SSB (Norway) server — StatFin and SSB both speak PxWeb, so the tools mirror each other.

Tools

Tool	What it does
`sok_tabell`	Keyword search across all StatFin tables. PxWeb has no server-side search, so this matches a bundled index (built from the full table tree) locally and returns the most relevant tables with their `tabell_id`.
`hent_tabell`	Metadata for a table: title + dimensions (variables) with their valid value codes and labels. Read this first to learn which filter codes exist.
`hent_data`	Fetch actual values as JSON-stat2, filtered by a flat `{variabelkode: [verdier]}` map. Supports special selections like `{filter:'top', values:['1']}` for the latest period.
`list_emner`	List the ~140 StatFin subject areas (e.g. `vaerak` = Population structure). Scope a search or browse when a keyword misses.

All tools accept an optional lang (en default, fi, sv). Variable codes are language-independent; only titles/labels are localised.

Example agent flow

sok_tabell({ query: "population by region" }) → tabell_id: "vaerak/statfin_vaerak_pxt_11ra.px"
hent_tabell({ tabell_id }) → sees variables Alue (area), Vuosi (year), Tiedot (info)
hent_data({ tabell_id, filtre: { Alue: ["SSS"], Vuosi: { filter: "top", values: ["1"] } } }) → latest national figures as JSON-stat2

Install

// Claude Desktop / Claude Code MCP config
{
  "mcpServers": {
    "statfin": {
      "command": "npx",
      "args": ["-y", "@nor-data/statfin-mcp"]
    }
  }
}

Develop

npm install
npm run build-index   # crawl the StatFin tree → data/tables-index.json (~1–2 min)
npm run dev           # run from source via tsx
npm run build         # compile to dist/

The search index is bundled in the package (data/tables-index.json). Re-run npm run build-index to refresh it (nightly is plenty — StatFin updates tables, not the tree, frequently).

Notes & limits

PxWeb allows 30 calls / 10 s and rejects queries over ~100 000 cells (HTTP 403) — keep hent_data selections small (few regions × few years).
A few subjects (vtp, kivih, sekn, akay) return HTTP 400 server-side and are skipped during indexing; this is a StatFin quirk, not a bug here. The index records them under skipped.
