Connect EUR-Lex to ChatGPT
Query EUR-Lex directly from ChatGPT. Arlet links the two through one MCP connection and takes care of API keys.
Connects your AI client to EUR-Lex through the Publications Office Cellar SPARQL endpoint.
Tools:
- search_eu_legislation: find works whose English title contains the given words. Returns title, document date and a EUR-Lex link.
- get_eu_document_by_celex: look up one document by CELEX number (e.g. '32016R0679' for the GDPR).
Why this is useful: Cellar is a linked-data endpoint whose model (work / expression / manifestation, language-specific titles) is hard to query by hand. This server hides that behind two plain tools, which is exactly the differentiation noted in the backlog. Titles are read from the English expression, so non-English-only documents may not match.
