Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

claude mcp add lu-eli -- uvx lu-eli-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "lu-eli": {

Common questions

Is Lu Eli MCP 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (0.3.3) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

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

Tool	What 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).
`lu_coverage()`	Declare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback.

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:

Variable	Meaning
`LU_ELI_BASE_URL`	Legilux data host (default `https://data.legilux.public.lu`).
`LU_ELI_CACHE_DIR`	Disk cache dir (default `~/.matematic/cache/lu-eli`).
`LU_ELI_AUDIT_DIR`	Audit log dir (default `~/.matematic/audit`).

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