Overview

LexAPI MCP

Model Context Protocol server for LexAPI — query EUR-Lex, EU case law, and the citation graph from Claude, Cursor, and other MCP-enabled AI tools.

Ask your assistant: "summarize Article 17 of the GDPR" or "which regulations amend Directive 95/46/EC?" and the model calls LexAPI directly.

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.

Install
