(Budowanie ze źródeł — niżej.)

An MCP server for Luxembourg legislation via Legilux open data (data.legilux.public.lu). It fetches act metadata and full Akoma Ntoso text with verifiable citations. Part of the eu-legal-mcp line of national legal connectors by MateMatic.

Legilux is genuinely ELI-native: every act is addressed by its ELI and described as jolux RDF over a FRBR model (Work / Expression / Manifestation), with full text as Akoma Ntoso XML. Every response carries a native eli_uri, a human_readable_citation and a resolvable source_url.

Read-only. The server only queries Legilux and writes a local audit log. It never modifies official text.

Tools

Tool	What it does
`lu_get_act(eli)`	Metadata for an act by its ELI (full URI or bare `eli/...` path). Returns the native `eli_uri`, title, dates, in-force status, available languages / manifestations, and the act's `cites` / `modifies` / `repeals` links.
`lu_get_text(eli, language, file_format)`	Verbatim text in one `language` (default `fr`) and `file_format` (default `xml`, Akoma Ntoso).

There is no free-text search: Legilux exposes no HTTP search endpoint. Discover acts by ELI coordinates (from legilux.public.lu) or by following the cites / modifies / repeals ELIs that lu_get_act returns. Luxembourg is multilingual, so titles and text may be French or German; the languages field shows what exists for a given act.

Configuration

Legilux is keyless. Configuration is optional:

Variable	Meaning
`LU_ELI_BASE_URL`	Legilux data host (default `https://data.legilux.public.lu`).
`LU_ELI_CACHE_DIR`	Disk cache dir (default `~/.matematic/cache/lu-eli`).
`LU_ELI_AUDIT_DIR`	Audit log dir (default `~/.matematic/audit`).

Copy .mcp.json.example to your MCP client config.
