conformi-search — EU Legal Research MCP Server

Verifiable EU law for AI agents — every answer carries a CELEX number and an EUR-Lex deep link.

Language: English · Deutsch · Français

MCP server for EU legal research with verifiable CELEX citations from the EUR-Lex corpus (German, English, French — each a native-language index, not machine translations). It exposes selected EU legal research tools to any MCP client and can optionally use a conformi API key for extended semantic search.

Research tool with primary-source citations — not legal advice, no attorney-client relationship.

Why this exists

LLMs answer EU-law questions plausibly but unverifiably. conformi-search returns answers that are checkable against the primary source: each result carries the CELEX number and a direct EUR-Lex link, so an agent (or a human) can verify the citation instead of trusting a hallucination. Works in Claude Code, Claude Desktop, Cursor, and any other MCP-capable harness.

Two ways to use it

1. Run it locally (stdio) — installable MCP server, no key needed for the free tools:

npm install && npm run build
node dist/index.js

Or with Docker:

docker build -t conformi-search-mcp .
docker run -i conformi-search-mcp

Add to an MCP client (e.g. Claude Desktop) config:

{
  "mcpServers": {
    "conformi-search": {
      "command": "node",
      "args": ["/path/to/conformi-search-mcp/dist/index.js"],
      "env": { "CONFORMI_API_KEY": "cfm_live_…  (optional, enables search_eu_law)" }
    }
  }
}

Without CONFORMI_API_KEY the two free tools are available. Setting the key adds the metered search_eu_law tool.

2. Use the hosted remote endpoint directly (Streamable HTTP, stateless):
