EUR-Lex

FreeEuropean Union

The European Union's official legal database, covering regulations, directives, decisions and treaties currently in force across all 27 member states, plus judgments, orders and Advocate General opinions from the Court of Justice and the General Court. Documents are tagged with the EuroVoc subject thesaurus and cross-linked by amendment, repeal, legal-basis and citing-case relationships, so a search can follow a provision or ruling forward and backward through the whole body of EU law. Full text and metadata are free to reuse (metadata is public domain under CC0; documents under Commission Decision 2011/833/EU, with source attribution). Access the web interface directly at eur-lex.europa.eu, or connect an MCP client (Claude, Cursor, and others) to the eur-lex-mcp-server connector — no API key needed — to search legislation and case law, resolve CELEX/ELI/ECLI citations, retrieve full document or judgment text, and trace a provision's amendment and citation history programmatically. A separate SOAP search service is also available directly from EUR-Lex for registered users who want search without going through an MCP client, though it returns metadata only, not document text. Keyword search covers titles and CELEX numbers rather than full document bodies — once you have an identifier from a search, the document/case-retrieval tools return the complete text.
