Connect EUR-Lex to Copilot Studio
Query EUR-Lex directly from Copilot Studio. 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.

On the Select a connection screen, choose Create new connection → Create, then sign in with Google on the Arlet authorization screen and click Allow. Click Add to attach the tool to the agent, then Publish to use it from Microsoft 365 Copilot.
Requires a Microsoft work account and a Copilot Studio license (or trial). MCP is available only for agents using generative orchestration and not in Copilot Studio in Teams.
