(Budowanie ze źródeł — niżej.)

An MCP server for the French Legifrance API via PISTE. It searches French legislation (LODA laws & decrees, codes), case law from three jurisdictions - Cour de cassation / cours d'appel (JURI), the Conseil constitutionnel (CONSTIT - QPC/DC decisions) and the administrative courts (CETAT - Conseil d'Etat, cours administratives d'appel, tribunaux administratifs) - plus CNIL deliberations (CNIL), collective labour agreements (KALI) and company-level agreements (ACCO), and returns verbatim text with verifiable citations. Part of the eu-legal-mcp line of national legal connectors by MateMatic.

Every response carries the citation contract: a stable eli_uri, a human_readable_citation (French convention) and a resolvable source_url.

Read-only. The server only queries Legifrance and writes a local audit log. It never modifies official text and never sends anything beyond your query / document id.

Jurisdictions covered

Conseil constitutionnel decisions get the French citation convention: Cons. const., decision n° 2025-1173 QPC du 7 novembre 2025 - [case name]. JURI/CETAT decisions cite the Legifrance titre (court, formation, date, dossier number) verbatim.

Judilibre (api.piste.gouv.fr/cassation/judilibre) was evaluated as an alternative Cour de cassation source but requires its own PISTE API subscription beyond the Legifrance one already held by this connector. Re-verified 2026-07-08: a valid Legifrance token (granted scope openid resource.READ) gets 403 on the sandbox host for every endpoint and auth shape tried (Bearer, KeyId, no-auth -> 400), and the sandbox application is rejected outright by the production OAuth endpoint (invalid_client). Subscribing the Judilibre API to the PISTE application is a dashboard action outside this connector. Not integrated - JURI already covers Cour de cassation case law through the existing Legifrance subscription.

A note on ELI vs ECLI

France has an official ELI scheme, but the PISTE lf-engine-app consult API returns the native ELI field null for the legislation we tested. Following this line's rule - say what you do not have, never fabricate an ELI - eli_uri carries the stable, resolvable Legifrance resource URL (CID-keyed), not a /eli/... string parsed from prose. Each response repeats this in eli_note.

Case law is different: the API returns a native, authoritative ECLI for Cour de cassation (e.g. ECLI:FR:CCASS:2025:C100399), Conseil constitutionnel (e.g. ECLI:FR:CC:2025:2025.1173.QPC) and Conseil d'Etat (e.g. ECLI:FR:CECHR:2026:506507.20260529), surfaced verbatim in fr_get_decision. CAA/TA decisions under CETAT frequently have no ECLI - the field is null, never fabricated.

Configuration

Legifrance requires OAuth2 application credentials from a free PISTE account (piste.gouv.fr → Applications → subscribe to the Legifrance API → OAuth Credentials). Credentials are read from the environment only:

Copy .mcp.json.example to .mcp.json (gitignored) and fill in your credentials, or set the variables in your host environment. The OAuth token is cached in memory and refreshed automatically.

Install

py -3.13 -m venv .venv
.\.venv\Scripts\python.exe -m pip install -e ".[dev]"   # Windows
# or: python -m pip install -e ".[dev]"                  # POSIX

Tests

pytest tests/test_instructions_drift.py tests/test_parse.py   # offline, no creds
pytest tests/test_smoke.py -v                                 # live, needs PISTE creds in .env

Distribution

Because Legifrance requires a PISTE key, this connector is distributed through the PATRON / appliance channel (governed), not casual drop-in download. See the eu-legal-mcp line notes.
