MCPpedia last refreshed this data
This server has been archived and is no longer actively maintained.
io.github.3121n/statfin-mcp is an MCP server that statistics Finland (StatFin/PxWeb): search tables, read metadata, fetch JSON-stat2 data. Its tool list has not been published yet over stdio and sse, requires no API key, and scores 73/100 on MCPpedia's security, maintenance and efficiency rubric.
Config is the same across clients — only the file and path differ.

Packing does not respect root-level ignore files in workspaces
### Impact `npm pack` ignores root-level `.gitignore` & `.npmignore` file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up
Incorrect Permission Assignment for Critical Resource in NPM
An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.
Local Privilege Escalation in npm
Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.
npm CLI exposing sensitive information through logs
Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.
npm Vulnerable to Global node_modules Binary Overwrite
Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b

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.
| 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.

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).
