Finnish Law Mcp

Finnish Law MCP Server

The Finnish law corpus is now served through the Ansvar Gateway. Connect your AI assistant (Claude, Copilot, Cursor, custom MCP client) to https://gateway.ansvar.eu/mcp — one OAuth connection, free tier available, covering this corpus plus EU regulations, national law across dozens of audited jurisdictions (Europe + the US), and CVE/security intelligence, every result with a verbatim source citation. Start at https://ansvar.eu/docs/quickstart

Connect

Claude Code (one line):

claude mcp add ansvar --transport http https://gateway.ansvar.eu/mcp

Claude Desktop / Cursor — add to claude_desktop_config.json (or mcp.json):

{  "mcpServers": {    "ansvar": {      "type": "url",      "url": "https://gateway.ansvar.eu/mcp"    }  }}

Claude.ai — Settings → Connectors → Add custom connector → paste https://gateway.ansvar.eu/mcp

First request opens an OAuth signup flow (setup details: ansvar.eu/docs/quickstart). After signup, your client is bound to your account; tier (free / premium / team / company) determines fan-out, quota, and which downstream MCPs are reachable.

Self-host this MCP

You can also clone this repo and build the corpus yourself. The schema, fetcher, and tool implementations all live here. What is not in the repo is the pre-built database — TDM and standards-licensing constraints on the upstream sources mean we host the corpus on Ansvar infrastructure rather than redistribute it as a public artifact.

Build your own: run this repo's ingestion script (entry-point varies per repo — typically scripts/ingest.sh, npm run ingest, or make ingest; check the repo root).

The Finlex alternative for the AI age.

[MCP Registry] [License] [GitHub stars] [CI] [Daily Data Check] [Database] [Provisions]

Query Finnish statutes -- from Tietosuojalaki and Rikoslaki to Osakeyhtiölaki, Ympäristönsuojelulaki, and more -- directly from Claude, Cursor, or any MCP-compatible client.

If you're building legal tech, compliance tools, or doing Finnish legal research, this is your verified reference database.

Built by Ansvar Systems -- Helsinki, Finland

Why This Exists

Swedish legal research is scattered across Riksdagen, SFS publications, lagen.nu, and EUR-Lex. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking if a statute is still in force
• A legal tech developer building tools on Swedish law
• A researcher tracing legislative history from proposition to statute

...you shouldn't need 47 browser tabs and manual PDF cross-referencing. Ask Claude. Get the exact provision. With context.

This MCP server makes Swedish law searchable, cross-referenceable, and AI-readable.

Example Queries

Once connected, just ask naturally:

• "What does Dataskyddslagen 3 kap. 5 § say about consent?"
• "Is PUL (1998:204) still in force?"
• "Find provisions about personuppgifter in Swedish law"
• "What EU directives does DSL implement?"
• "Which Swedish laws implement the GDPR?"
• "Get the preparatory works for Dataskyddslagen"
• "Compare incident reporting requirements across NIS2 Swedish implementations"
• "Validate the citation NJA 2020 s. 45"
• "Find Labour Court cases about discrimination from 2020-2023"

What's Included

Verified data only -- every citation is validated against official sources (Riksdagen, lagen.nu, EUR-Lex). Zero LLM-generated content.

See It In Action

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from Riksdagen/SFS official sources
• Provisions are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing -- the database contains regulation text, not AI interpretations

Smart Context Management:

• Search returns ranked provisions with BM25 scoring (safe for context)
• Provision retrieval gives exact text by SFS number + chapter/section
• Cross-references help navigate without loading everything at once

Technical Architecture:

Riksdagen API → Parse → SQLite → FTS5 snippet() → MCP response                  ↑                      ↑           Provision parser       Verbatim database query

Traditional Research vs. This MCP

Traditional: Search Riksdagen → Download SFS PDF → Ctrl+F → Cross-reference with proposition → Check EUR-Lex for EU basis → Repeat

This MCP: "What EU law is the basis for DSL 3 kap. 5 § about consent?" → Done.

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Riksdagen/SFS publications. However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is limited -- do not rely solely on this for case law research
• Verify critical citations against primary sources for court filings
• EU cross-references are extracted from Swedish statute text, not EUR-Lex full text

Before using professionally, read: DISCLAIMER.md | PRIVACY.md

Client Confidentiality

Queries go through the Claude API. For privileged or confidential matters, use on-premise deployment. See PRIVACY.md for Advokatsamfundet compliance guidance.

About Ansvar Systems

We build AI-accelerated compliance and legal research tools for the European market. This MCP server started as our internal reference tool for Swedish law -- turns out everyone building for the Swedish market has the same research frustrations.

So we're open-sourcing it. Navigating 717 statutes shouldn't require a law degree.
