French Law Mcp

French Law MCP Server

The French 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 28 audited jurisdictions, 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 Légifrance alternative for the AI age.

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

Query 3,958 French statutes -- from le RGPD (loi Informatique et Libertés), le Code pénal, and le Code civil to le Code du travail, le Code de commerce, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

French legal research is scattered across Légifrance, the Journal Officiel, legistix, and EUR-Lex. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking RGPD obligations or sectoral regulations
• A legal tech developer building tools on French law
• A researcher tracing legislative history from projet de loi to code

...you shouldn't need dozens of browser tabs and manual cross-referencing between codes. Ask Claude. Get the exact provision. With context.

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

Example Queries

Once connected, just ask naturally:

• "Que dit l'article 6 de la loi Informatique et Libertés sur le consentement ?"
• "Recherche 'protection des données personnelles' dans le droit français (RGPD, loi Informatique et Libertés)"
• "Quelles dispositions du Code pénal concernent la fraude informatique ?"
• "Trouve les articles sur le droit du travail liés aux heures supplémentaires dans le Code du travail"
• "What EU directives does the loi Informatique et Libertés implement?"
• "Which French laws implement the NIS2 Directive?"
• "Valide la citation 'Article L. 226-1 du Code pénal'"
• "Compare les exigences de notification d'incident sous NIS2 et la loi française de transposition"
• "Recherche 'responsabilité civile' dans le Code civil"
• "Get the premium case law for RGPD enforcement decisions"

What's Included

Verified data only -- every citation is validated against official sources (Légifrance, legifrance.gouv.fr). Zero LLM-generated content.

See It In Action

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from Légifrance official publications
• 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 code + article number
• Cross-references help navigate without loading everything at once

Technical Architecture:

Légifrance API --> Parse --> SQLite --> FTS5 snippet() --> MCP response                    ^                        ^             Provision parser         Verbatim database query

Traditional Research vs. This MCP

Traditional: Search Légifrance -> Navigate the code -> Ctrl+F -> Cross-reference with RGPD -> Check EUR-Lex for directive -> Repeat

This MCP: "Quels textes européens ont conduit à l'article L. 34-5 du Code des postes ?" -> Done.

EU Law Integration

France is a founding EU member state and plays a central role in EU law-making. French law has extensive EU cross-references across all major regulatory domains.

Key EU Acts with French Implementations

1. GDPR (2016/679) -- Loi Informatique et Libertés, CNIL decisions
2. NIS2 Directive (2022/2555) -- Loi relative à la résilience des infrastructures critiques
3. eIDAS Regulation (910/2014) -- Ordonnance n° 2017-1426 (identité numérique)
4. AI Act (2024/1689) -- Direct application + French adaptation measures
5. DORA (2022/2554) -- Direct application in financial sector

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Légifrance publications. However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is limited (premium tier) -- 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 French statute text, not EUR-Lex full text
• Regulatory guidance (CNIL, ANSSI decisions) is not included in the free tier

Client Confidentiality

Queries go through the Claude API. For privileged or confidential matters, use on-premise deployment. For guidance on professional obligations, consult the Conseil National des Barreaux (CNB). See PRIVACY.md for compliance guidance.

Data Licenses

Upstream legal materials are reused under the French Open Licence v2.0 (Licence Ouverte, Etalab) — Ansvar attribution code FR-Etalab-2.0.

• Statutes & Codes: DILA / Direction de l'information légale et administrative — published under Licence Ouverte v2.0. Commercial reuse permitted with attribution and licence-notice preservation.
• Case Law: Légifrance open data, same Etalab licence.
• EU Metadata: EUR-Lex (EU public-domain notice).

Important: French statutes are NOT in the public domain. France did not adopt a statutory-PD carve-out comparable to Germany (UrhG §5) or Spain (TRLPI Art. 13). The reuse basis is Etalab's open licence, which requires attribution and licence-notice preservation. The Ansvar attribution code FR-Etalab-2.0 is declared in infrastructure/attribution-licenses.json in the Ansvar architecture-documentation repo.

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 French law -- turns out everyone building for the French and EU markets has the same research frustrations.

So we're open-sourcing it. Navigating 3,958 statutes and codes shouldn't require a law degree.
