Common questions

Is mcp-belgium safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: STIB_API_KEY, CBEAPI_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.4) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

mcp-belgium

One MCP server for Belgian public APIs.

mcp-belgium is the public entry point. It exposes a single aggregated MCP server that bundles Belgian transport, official statistics, open data, addresses, weather, air quality, and geospatial services behind one install and one client config entry.

The package is also prepared for publication to the official MCP Registry under io.github.lacausecrypto/mcp-belgium.

Why use it

one npm package
one MCP server entry in your client config
namespaced tools like irail_*, statbel_*, best_*, kmi_*, urban_*, and urbis_*
built-in catalog tools, resources, and a prompt so the LLM can discover the right Belgian domain before calling tools
explicit limitation surfaces when an upstream requires a key or has changed contract

Install

Run directly:

npx -y mcp-belgium

With pnpm:

pnpm dlx mcp-belgium

Global install:

pnpm add -g mcp-belgium

mcp-belgium

Default transport is stdio, which is what desktop MCP clients expect.

Claude Desktop

"mcpServers": { "belgium": { "command": "npx", "args": [ "-y", "mcp-belgium" ], "env": { "LOG_LEVEL": "silent" } } } }

Optional env vars:

STIB_API_KEY: enables live STIB/MIVB tools
CBEAPI_KEY: enables live KBO/BCE company registry tools
MCP_TRANSPORT=http: runs the server over Streamable HTTP
PORT_BELGIUM=3017: sets the HTTP port for the aggregated server

What the LLM gets

Alongside the domain tools, mcp-belgium exposes a discovery layer:

belgium_catalog_overview
belgium_list_domains
belgium_describe_domain
belgium://catalog
belgium://catalog.json
belgium://domain/{domain}
belgium_capability_guide

That means the LLM can:

inspect the Belgian domains available from this single MCP
see which domains are live, limited, or key-gated
understand what kind of data each domain provides
pick the right namespaced tool without guessing

Main domains

Prefix	Domain	Status	Auth	Main data
`irail_*`	Belgian rail / iRail	Live	None	stations, connections, liveboards, vehicles, disruptions
`mobility_*`	Belgian mobility / SMOP	Live	None	intermodal trip planning, operators, GTFS references
`stib_*`	STIB/MIVB Brussels transit	Live	API key	waiting times, stops, routes, service messages
`infrabel_*`	Infrabel Open Data	Live	None	rail infrastructure datasets and records
`kbo_*`	Belgian company registry	Live	API key	enterprise search and company details
`best_*`	BeST Belgian addresses	Live	None	addresses, municipalities, streets, postal infos
`statbel_*`	Statbel	Live	None	population, CPI, employment, dataset search
`airquality_*`	IRCELINE air quality	Live	None	stations, live measurements, BelAQI, timeseries
`brussels_*`	Brussels Region open data	Live	None	datasets and records
`wallonia_*`	Wallonia open data	Live	None	datasets and records
`kmi_*`	KMI / IRM GeoServer	Live	None	stations, hourly observations, WFS discovery
`wallonia_geo_*`	Wallonia GeoServices	Live	None	ArcGIS folders, services, layer queries
`urban_*`	urban.brussels WFS	Live	None	feature types, schemas, GeoJSON features
`urbis_*`	URBIS public WMS	Live	None	WMS layer discovery and map URL generation
`datagov_*`	data.gov.be compatibility layer	Limited	None	explicit upstream-changed error surface
`flanders_*`	Datavindplaats compatibility layer	Limited	API key	explicit upstream limitation surface

Docs / Wiki

The repo now includes a docs/ tree that works as a lightweight public wiki:

Installation

Domain catalog
Development
Release and npm publishing

Local development

Requirements:

Node.js >= 22
pnpm >= 9

Setup:

pnpm install

pnpm run build pnpm run test pnpm run typecheck

Run the aggregated server over stdio:

pnpm --filter mcp-belgium start:stdio

Run it over Streamable HTTP:

MCP_TRANSPORT=http PORT_BELGIUM=3017 pnpm --filter mcp-belgium start

Run the whole workspace:

docker compose up --build

Monorepo shape

packages/core: shared HTTP, retry, cache, rate limiting, XML helpers, and MCP response helpers
packages/mcp-belgium: public aggregated entry point
packages/mcp-*: domain-specific packages kept modular for maintenance, testing, and isolated validation

The public consumer path is mcp-belgium. Internal workspace packages stay modular for development, but the published mcp-belgium package bundles them so end users install only one npm package.

Upstream caveats

This project wraps public upstream APIs. Some Belgian portals change authentication or endpoint contracts over time. When an upstream is no longer publicly compatible, this project prefers explicit, machine-readable limitation errors over silent failure.

Current examples:

mcp-stib requires STIB_API_KEY
mcp-kbo requires CBEAPI_KEY
mcp-data-gov-be preserves the old tool contract but returns an explicit upstream-changed error
mcp-opendata-flanders preserves the old tool contract but returns an explicit API-key limitation

Validation

Current workspace checks:

pnpm run build
pnpm run test
pnpm run typecheck
pnpm audit --prod
