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):

Tools

Tool	Auth	Billing
search_eu_law — semantic search across EU secondary law, results carry CELEX numbers + EUR-Lex deep links; optional valid_at time-travel filter	API key	metered per query
get_knowledge_article — curated report for one legal act (GDPR, AI Act, NIS2, DORA, CRA …) incl. legal-status (Rechtsstand) metadata	none	free
get_legal_timeline — application-date timeline for major acts (e.g. AI Act high-risk deadlines)	none	free

Getting an API key (machine-friendly)

The full contract incl. pricing and a machine-driven purchase flow is in the OpenAPI document:

Quick test (no key needed)

curl -X POST https://conformi.eu/api/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_knowledge_article","arguments":{"celex":"32024R1689"}}}'

Troubleshooting

Symptom	Cause & fix
search_eu_law returns isError with a purchase hint	No Authorization: Bearer key was sent. Free tools work without a key; search is metered — get a key via https://conformi.eu/api/v1/openapi.json
401 UNAUTHORIZED on search	Key invalid or revoked. Check the key in your conformi.eu account (Account → API Keys)
403 PLAN_REQUIRED / TRIAL_LIMIT_REACHED	Subscription inactive or the 50-query trial allowance is used up — activate the subscription
404 for a CELEX in get_knowledge_article	No curated report exists for that act yet. Try search_eu_law instead — the full corpus is searchable
Connection fails	The server speaks Streamable HTTP only (no SSE). POST JSON-RPC to https://conformi.eu/api/mcp; GET returns 405 by design
