Security Report

5.2

Moderate5.2Moderate Risk

be-eli-mcp is a well-structured MCP server for querying Belgian legislation with no authentication requirements (the upstream service is keyless and read-only). The codebase demonstrates good security practices including proper input validation, error handling, audit logging, and secure credential handling. Permissions are appropriately scoped to the server's purpose. Minor code quality observations exist but do not materially affect security posture. Supply chain analysis found 6 known vulnerabilities in dependencies (1 critical, 3 high severity). Package verification found 1 issue.

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

Tool	What it does
`be_get_act(doc_type, year, month, day, numac)`	Metadata for an act by its ELI coordinates. `doc_type` is one of `loi`, `decret`, `ordonnance`, `arrete`, `constitution`. Returns the native `eli_uri`, title, source authority, publication date, entry-into-force date, table of contents, and the citation contract.
`be_get_text(doc_type, year, month, day, numac, language="fr")`	The verbatim consolidated text ("Texte"/"Tekst" section) in `fr` (default), `nl` or `de`.
`be_list_year(doc_type, year)`	Browse a year's listing for one `doc_type`, to discover NUMAC coordinates. Titles in this listing are best-effort (may be `None`); call `be_get_act` for the authoritative title.

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.

Configuration

ejustice.just.fgov.be is keyless. Configuration is optional:

Variable	Meaning
`BE_ELI_BASE_URL`	ejustice host (default `https://www.ejustice.just.fgov.be`).
`BE_ELI_CACHE_DIR`	Disk cache dir (default `~/.matematic/cache/be-eli`).
`BE_ELI_AUDIT_DIR`	Audit log dir (default `~/.matematic/audit`).

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