{
  "mcpServers": {
    "io-github-matematicsolutions-lu-eli-mcp": {

lu-eli-mcp

Install (one command)

Published on PyPI + MCP Registry (io.github.matematicsolutions/lu-eli-mcp). Run without cloning:

uvx lu-eli-mcp

Configure your MCP client (stdio):

{ "mcpServers": { "lu-eli-mcp": { "command": "uvx", "args": ["lu-eli-mcp"] } } }

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the lu-eli-mcp.exe launcher that pip writes at install time. The python.exe and py.exe from the python.org installer are signed by the Python Software Foundation, so running the module through the interpreter works:

python -m pip install lu-eli-mcp
python -m lu_eli_mcp

pip.exe is blocked for the same reason, so install with python -m pip, not pip install. If python is not on PATH, use the Windows launcher: py -3 -m lu_eli_mcp.

{ "mcpServers": { "lu-eli-mcp": { "command": "python", "args": ["-m", "lu_eli_mcp"] } } }

Do not turn Smart App Control off to work around this - it cannot be re-enabled without reinstalling Windows.

Building from source: see Install.

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

ToolWhat 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:

VariableMeaning
LU_ELI_BASE_URLLegilux data host (default https://data.legilux.public.lu).
LU_ELI_CACHE_DIRDisk cache dir (default ~/.matematic/cache/lu-eli).
LU_ELI_AUDIT_DIRAudit log dir (default ~/.matematic/audit).

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