# LibreJustice

> Free, open-source search engine for French and European law: court decisions
> (both the administrative and the judicial order) and legal texts (French codes
> at any past date, EU law, treaties, collective agreements, administrative
> doctrine). Rebuilt daily from official sources.

## Searching: connect the MCP server, do not crawl

The corpus is millions of decisions and more than a million texts. Fetching
pages one by one will not find the relevant one — the search engine will. It is
exposed as a Model Context Protocol server, free and open to any client:

- Endpoint: https://librejustice.fr/mcp
- Transport: streamable-http. Auth: OAuth, auto-discovered (RFC 9728 metadata at
  /.well-known/oauth-protected-resource).
- Setup per client (Claude, ChatGPT, Codex, Cursor, Mistral…): https://librejustice.fr/mcp-guide

Tools:

- `search_decisions` — case law, hybrid meaning + keyword matching, with
  structured filters (jurisdiction, dates, cited articles, codes) and facet
  counts to refine. Quoted phrases and the `ET` / `OU` / `SAUF` / `PROCHE<n>`
  operators switch to exact-wording matching — the only way to target which way
  a court ruled, since semantic matching ignores negations.
- `get_decision` — full text of one decision, with inline links to the articles
  and decisions it cites. Also reports whether the decision still stands
  (`appellateFate`: reversed or upheld on review) and the linked prior and
  subsequent decisions of the same case. Read that before citing it as authority.
- `search_legal_texts` — finds statutory articles from their subject or wording
  when the article number is unknown; ranked snippets, facets by code.
- `get_legal_text` — one article as it read on a given date (or today), with its
  status, validity dates and the timeline of every version. Say which version
  you quote.

Queries are written in French: it is a French-language corpus.

## Browsing (crawlable trees, for humans and indexers)

Two symmetric trees, one per corpus, plus a directory of parties:

- https://librejustice.fr/juridictions — courts, then year, then decisions.
  A decision: /decision/{id}
- https://librejustice.fr/normes — funds (codes, lois, décrets, arrêtés,
  collective agreements, EU texts, treaties, circulaires, BOFiP), then year,
  then texts. An article: /texte/{code}/{article}, or
  /texte/{code}/{article}/{date} for the version in force at that date.
- https://librejustice.fr/annuaire — companies, public bodies, associations and
  counsel appearing in the decisions.

Search pages: /decisions (case law), /textes (legal texts).
