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.
Install
You'll need a LexAPI API key. Create one for free at lex-api.com/dashboard (500 credits/month on the FREE tier, no card required).
Claude Desktop
Add to claude_desktop_config.json (location: ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):
Restart Claude Desktop.
Claude Code
Cursor / other MCP clients
Any client that supports stdio MCP servers can run this. The command is npx -y @lexapi/mcp with LEXAPI_API_KEY in the environment.
Tools
| Tool | What it does |
|---|---|
| lex_search | Structured EUR-Lex search (text, dates, document type, author, language). |
| lex_get_document | Full parsed document by CELEX — metadata + articles, sections, tables, annexes. |
| lex_get_metadata | Metadata only (faster than full content). |
| lex_get_document_by_url | Fetch by EUR-Lex URL (pasted from a browser). |
| lex_recent_documents | Recent Official Journal publications (default 7 days). |
| lex_cited_by | Documents citing this CELEX (inbound, typed edges). |
| lex_cites | Documents this CELEX cites (outbound, typed edges). |
| lex_citation_network | Both directions in one call. |
| lex_semantic_case_law | Embedding search over EU case law (paid plans). |
| lex_semantic_legislation | Embedding search over EU legislation (paid plans). |
Configuration
| Env var | Default | Purpose |
|---|---|---|
| LEXAPI_API_KEY | *(required)* | Your API key. Get one at lex-api.com/dashboard. |
| LEXAPI_BASE_URL | https://lex-api.com/api/v1 | Override for self-hosted or staging. |
Troubleshooting
**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.
