You can use the French Law MCP Server to query French legal provisions, validate and format citations, cross-reference EU regulations, and run contract tests with drift checks. It combines seeded Legifrance data, citation tools, and EU references to enable fast, reliable access for legal research and development workloads.

How to use

Connect your MCP client to the deployed or local server to perform searches, fetch provisions, and validate citations. Use the HTTP endpoint for remote deployments, or run a local stdio version for development and testing. You will access tools for searching legislation, retrieving provisions, validating and formatting citations, and checking currency and EU references.

How to install

Prerequisites: Node.js and npm installed on your system. You will also need a readable internet connection to fetch dependencies and seed data.

# Local development setup
npm install
npm run build
npm run dev

Additional sections

Deployment and runtime information: you can run the MCP locally during development or deploy to a hosting environment that serves the MCP via HTTP. For remote access, you can connect clients to a Vercel-hosted endpoint at the standard path /mcp. Health and version endpoints are available at /health and /version.

Data sources and seeds: the primary legal data comes from Legifrance open data (DILA) with EU references linked to EUR-Lex metadata. Seed files live under data/seed and the built database is data/database.db.

Development and testing commands cover a comprehensive workflow, including building the SQLite database from seeds, running unit and contract tests, and performing drift detection against upstream data.

Vercel deployment uses a Streamable MCP HTTP transport with api/mcp.ts handling requests and api/health.ts providing health and version endpoints. Runtime configuration is defined in vercel.json.

Operational notes: this tool is for legal research and should not be used as legal advice. Always verify critical citations against official publications.
