Belgian MCP Server

Belgian legislation via MCP — full-text search across statutes and provisions

Local serverstdioTypeScript

What is the Belgian MCP server?

Belgian legislation via MCP — full-text search across statutes and provisions. Exposed over MCP by the belgian mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

First request opens an OAuth signup flow (setup details: ansvar.eu/docs/quickstart). After signup, your client is bound to your account; tier (free / premium / team / company) determines fan-out, quota, and which downstream MCPs are reachable.

We build AI-accelerated compliance and legal research tools for the European market. This MCP server started as our internal reference tool for Belgian and EU institutional law -- turns out everyone working at the EU-national interface has the same research frustrations.

  • A lawyer validating citations in a brief or contract
  • A compliance officer checking GDPR implementation or Loi anti-blanchiment requirements
  • A legal tech developer building tools on Belgian or EU institutional law
  • A researcher tracing EU institutional decisions back to Belgian implementation

Its toolset

Everything the assistant can do here goes through one of these:

  • search_legislation — FTS5 search on 142,743 provisions with BM25 ranking
  • get_provision — Retrieve specific provision by statute identifier + article
  • validate_citation — Validate citation against database (zero-hallucination check)
  • build_legal_stance — Aggregate citations from statutes and agency guidance
  • format_citation — Format citations per Belgian conventions (full/short/pinpoint)
  • check_currency — Check if statute is in force, amended, or repealed
  • list_sources — List all available statutes with metadata and data provenance
  • about — Server info, capabilities, dataset statistics, and coverage summary
  • get_eu_basis — Get EU directives/regulations for Belgian statute
  • get_belgian_implementations — Find Belgian laws implementing EU act
  • search_eu_implementations — Search EU documents with Belgian implementation counts
  • get_provision_eu_basis — Get EU law references for specific provision

Adding it to your client

@anthropic/mcp-inspector on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

When to reach for it

Plenty of database access servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Belgian's toolset — search_legislation, get_provision, validate_citation and 11 more — is a fair guide to whether it matches your workflow. It is maintained by eu.ansvar; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Belgian.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the belgian mcp server does with a few real requests.

Frequently asked questions

It connects Belgian to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (search_legislation, get_provision, validate_citation, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Belgian directly.
