MCP server for Finnish Finlex consolidated statutes: ELI identifiers and verifiable citations.

Overview

AI-generated overview

Local MCP server that lets an assistant look up Finnish consolidated statutes from the Finlex open-data API, with ELI identifiers and verifiable citations.

What you can do
List the statutes of a given year for discovery, or look up a statute by year and number (the API is path-based, not keyword search). Retrieve metadata for a statute, including its ELI URI, human-readable Finnish citation and source URL. Fetch the full Akoma Ntoso 3.0 XML text of a statute. Report what the connector covers, when each family was captured, and which gaps exist with fallbacks.
When to use it
Useful when you need to read or cite Finnish legislation (saadokset) and want checkable references rather than free-text answers. Suited to legal research, compliance checks or drafting that depends on the current consolidated text of a Finnish act.
Requirements
Runs locally over stdio, installed from PyPI with uvx or pip (Python). No API key: Finlex open data is keyless. Optional environment variables set the base URL, cache directory and audit directory. Needs network access to the Finlex open-data API and the local filesystem.
Before you install
Read-only against Finlex, but every tool call appends a JSON line to a local audit log. On first use it may fetch a small configuration file from the project's GitHub Releases; this can be disabled with FI_ELI_RUNTIME_URL set to empty. Titles may be Finnish or Swedish. Coverage is limited to Finnish statutes, not all Finlex content.

Installation

In SourceWeft

  1. Open Fi Eli Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Install (one command)

As a Claude plugin (Claude Code or the desktop app, needs uv); see plugin/README.md for what it sends and stores:

/plugin marketplace add matematicsolutions/fi-eli-mcp/plugin install fi-eli-mcp@fi-eli-mcp

Published on PyPI + MCP Registry (io.github.matematicsolutions/fi-eli-mcp). Run without cloning:

bash
uvx fi-eli-mcp

Configure your MCP client (stdio):

json
{ "mcpServers": { "fi-eli-mcp": { "command": "uvx", "args": ["fi-eli-mcp"] } } }

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the fi-eli-mcp.exe launcher that pip writes at install time. The python.exe and py.exe from the python.org installer are signed by the Python Software Foundation, so running the module through the interpreter works:

bash
python -m pip install fi-eli-mcppython -m fi_eli_mcp

pip.exe is blocked for the same reason, so install with python -m pip, not pip install. If python is not on PATH, use the Windows launcher: py -3 -m fi_eli_mcp.

json
{ "mcpServers": { "fi-eli-mcp": { "command": "python", "args": ["-m", "fi_eli_mcp"] } } }

Do not turn Smart App Control off to work around this - it cannot be re-enabled without reinstalling Windows.

Building from source: see Install.

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

ToolWhat it does
fi_list_actsList the statutes of a year (discovery).
fi_get_actMetadata for a statute by year + number.
fi_get_textFull Akoma Ntoso text of a statute by year + number.
fi_coverageDeclare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback.

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

bash
cd fi-eli-mcppip install -e .

Configure (Claude Code / any MCP client)

json
{  "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.
  • Network - the server talks to the official source(s) named above and the local filesystem. Once, on first use, it also fetches a small configuration file (fi-runtime.json.gz, updated source addresses) from this repository's GitHub Releases. That request carries no query content; GitHub's download counter for the file is the only usage signal we see. FI_ELI_RUNTIME_URL="" turns it off; the Claude plugin ships with it off. No LLM provider, no other telemetry.
  • Verifiable citations - every response is independently checkable via source_url.

See CONSTITUTION.md and DISCOVERY.md.
