(Budowanie ze źródeł — niżej.)

An MCP server for the Finnish Finlex open-data API (opendata.finlex.fi). It fetches consolidated Finnish statutes as Akoma Ntoso 3.0 XML, with verifiable ELI identifiers and Finnish citations.

Part of the MateMatic eu-legal-mcp production line - after PL, DE, AT and ES. Same citation contract, Finlex source.

Scope. This MVP covers Finnish statutes (saadokset). Discovery is by year (fi_list_acts) or by year + number; the open-data API is path-based, not keyword search. Finland is bilingual, so titles may be Finnish or Swedish. Every response carries a dataset_note.

Licence. Finnish legislation in Finlex is official public information published as open data (keyless). This connector relays it with attribution and a source_url.

The tools

Every response carries the contract: eli_uri (a full ELI URL, e.g. http://data.finlex.fi/eli/sd/2018/1050/alkup), human_readable_citation (e.g. Tietosuojalaki (1050/2018)), and source_url.

Install

cd fi-eli-mcp
pip install -e .

Configure (Claude Code / any MCP client)

{
  "mcpServers": {
    "fi-eli-mcp": { "command": "fi-eli-mcp" }
  }
}

Environment:

• FI_ELI_BASE_URL - default https://opendata.finlex.fi/finlex/avoindata/v1

• FI_ELI_CACHE_DIR - default ~/.matematic/cache/fi-eli

• FI_ELI_AUDIT_DIR - default ~/.matematic/audit

No API key. Finlex open data is keyless.

Governance

• Public data only - read-only against Finlex; no client data leaves the machine.

• Audit log - every tool call appends one JSON line to ~/.matematic/audit/fi-eli-mcp.jsonl.

• Vendor-neutral - talks only to opendata.finlex.fi; no LLM provider, no telemetry.

• Verifiable citations - every response is independently checkable via source_url.

See CONSTITUTION.md and DISCOVERY.md.
