Justicelibre

dahliyaal/justicelibre

Exposes 3.3 million French court decisions and 1.5 million consolidated legal articles through 29 MCP tools covering everything from Cour de cassation to CJUE to CEDH. The killer feature is get_law_article with historical versioning so you can pull the exact text of Code Civil article 1128 as it read in 1992 versus today. Search runs BM25 ranking with authority bonuses, fan-out queries hit all 40 administrative tribunals in parallel, and cross-reference tools show which decisions cite specific articles. Runs over streamable HTTP with no auth required, making it immediately usable from Claude.ai or ChatGPT without OAuth friction. Built as an open alternative to paywalled services like Doctrine and Lexis that cost 50 to 200 euros monthly.
