BOE Open Data

Provided by Agencia Estatal Boletín Oficial del Estado (BOE)

Official open-data API of Spain's Boletín Oficial del Estado (BOE), the national gazette agency: consolidated national legislation (acts, decrees, with ELI identifiers and article-level text), Tribunal Constitucional rulings (resolved by case number, with ECLI citations), and binding administrative doctrine from the tax authority (DGT rulings), the Central Economic-Administrative Tribunal (TEAC criterios), and the data-protection authority (AEPD resolutions). Access is free and keyless directly from BOE's own API; an open-source MCP connector (es-eli-mcp) exposes it to Claude and other MCP clients with dedicated tools per source — consolidated-text retrieval for legislation, citation lookup for Tribunal Constitucional rulings, and full-text/date search for DGT and AEPD. It's an early-stage, single-maintainer project: TEAC search doesn't yet support text filtering, and BOE's own keyword search endpoint isn't currently reliable through this connector — legislation lookups work best by known identifier (ELI/BOE id) rather than full-text search for now.

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.
