    MCP Legal Pro Server — French Legal API for AI (TypeScript, OAuth2 PISTE, CI/CD)
    March 2026 - April 2026 (1 month)
    Commercial MCP (Model Context Protocol) server that I designed, developed, and deployed from scratch. It gives AI assistants (Claude, ChatGPT, Cursor, custom agents) structured and compliant access to official French legal sources: Légifrance, JUDILIBRE (Court of Cassation), BOFiP-Impôts, and KALI (collective agreements).

    ## Problem Addressed


    An LLM wanting to answer a French legal question today must make 3 to 4 calls to different APIs, each with its own schema and compliance rules. The server aggregates these sources into a single call, intelligently cross-references results by domain (labor, tax, civil, commercial, social, etc.), and returns concrete deliverables (PDF, CSV/JSON/Markdown exports) with all license and enforceability notices preserved.
