Libre Justice MCP Server

librejustice.fr: a free search engine for French and European law, plus current public notices. It links case law from France's administrative and judicial courts to consolidated legal texts and makes them searchable in plain language on the web and through MCP. It is available as a remote MCP endpoint.

Teams that work with case law, claude skills and france and want a hosted endpoint instead of running a local process. The project is written in Rust.
