Model Context Protocol server for LexAPI — query EUR-Lex, EU case law, and the citation graph from Claude, Cursor, and other MCP-enabled clients.
Install once, get an API key, and ask your AI assistant: "summarize Article 17 of the GDPR" or "which regulations amend Directive 95/46/EC?" — the model calls LexAPI directly.
You'll need a LexAPI API key. Create one for free at lex-api.com/dashboard (50 calls/day on the FREE tier).

`LEXAPI_API_KEY is not set` — the env var isn't reaching the spawned process. Double-check the env block in your MCP client config.
`LexAPI error (401 invalid_api_key)` — the key is wrong or revoked. Generate a new one at the dashboard.
`LexAPI error (429 …)` — you hit your daily quota or per-minute rate limit. The server retries once automatically; if you see this in tool output, you're over quota. Upgrade your plan or wait for reset.
`LexAPI error (403 …)` on semantic tools — semantic search requires a paid plan. FREE tier returns 403 for those endpoints.
