mcp-fr-legal
Serwer MCP udostepniajacy offline korpus prawa francuskiego (Legifrance/DILA, pelny tekst)
w lokalnym SQLite FTS5, z narzedziami do wyszukiwania i groundingu cytatu. Snippety zwracane
verbatim z bazy (zero-LLM) - kazdy z document_id, provision_ref i URL do Legifrance.
Anti-halucynacja przez mechanike, nie przez zaufanie do modelu.
Zakres: kody i ustawy skonsolidowane LEGI (Code civil, Code du travail, Code penal, Code de commerce, Code de la defense, Code de la securite interieure, ...) - 3 953 dokumenty / 193 681 przepisow w bundlowanym snapshocie. Bez orzecznictwa (jurisprudence) i bez pelnego JORF.
Rodzina konektorow prawa MateMatic: mcp-saos
(orzecznictwo PL), mcp-eu-compliance
(prawo UE), mcp-eu-sparql (live EUR-Lex).
Instalacja

npm run build
npm start
Air-gap / pelny offline: ustaw FR_LEGAL_DB na lokalna kopie database.db.

Narzedzia
| Tool | Opis |
|---|---|
fr_search(query, documents?, limit?) |
Pelnotekstowo (FTS5) po przepisach, snippety verbatim + citations. |
fr_article(document_id, provision_ref) |
Pelny verbatim tekst przepisu (tolerancyjny provision_ref). |
fr_validate_citation(document_id, provision_ref) |
Grounding: czy cytat istnieje (fail-closed) - anti-halucynacja. |
fr_list_documents(type?, query?) |
Lista dokumentow (discovery document_id). |
Kazde narzedzie zwraca structuredContent.citations (document_id, provision_ref, URL Legifrance,
source_authority DILA, license Etalab v2.0, snapshot, age_days oraz staleness_advisory
gdy snapshot starszy niz prog FR_STALENESS_DAYS (domyslnie 365) - provenance/staleness wzorowane na
russellbrenner/jurisd, Apache-2.0).
Grounding (anti-halucynacja)
fr_validate_citation to prymityw groundingu: sprawdza mechanicznie, czy document_id + provision_ref
istnieje w korpusie. Fail-closed - brak dokumentu/przepisu => provision_exists=false (nie
"prawdopodobnie ok"). Spina sie z citation-grounding-pl
jako resolver kotwicy dla prawa FR (poziom ISTNIENIE).
Zero-cloud / RODO
Zero wywolan sieciowych w runtime (baza otwierana read-only). Bootstrap korpusu (fetch-corpus) to
jedyny moment sieci. Tekst zwracany verbatim (grounding). Swiezosc: sprawdzaj na Legifrance (snapshot
!= zrodlo autentyczne = Journal officiel).
