be-eli-mcp

An MCP server for Belgian legislation via [Moniteur Belge / Belgisch Staatsblad] (https://www.ejustice.just.fgov.be), the official gazette of the Belgian Federal Public Service Justice. It fetches act metadata and full text by ELI coordinates, with verifiable citations. Part of the eu-legal-mcp line of national legal connectors by MateMatic.

Belgian legislation is addressed by ELI coordinates - type / year / month / day / numac (the Belgian legislative numbering system) - at https://www.ejustice.just.fgov.be/eli/{type}/{yyyy}/{mm}/{dd}/{numac}/justel. Every response carries a native eli_uri, a human_readable_citation and a source_url.

Read-only. The server only queries ejustice.just.fgov.be and writes a local audit log. It never modifies official text.

Belgium is trilingual (French / Dutch / German). human_readable_citation defaults to the French form by LDH convention; use be_get_text(language=...) for Dutch (Belgisch Staatsblad) or German. See CONSTITUTION.md Art. 4 for the full caveat.

Tools

There is no free-text search: ejustice.just.fgov.be exposes no keyword-search API. Discover acts by ELI coordinates (from a citation you already hold) or by browsing be_list_year.
