Moonlit MCP

The Moonlit MCP server connects Claude and any MCP-compatible client to European legal data: legislation, case law, and supervisory guidance from official portals.

What it does

The server exposes read-only legal research tools to your AI assistant. The model picks which tool to call; you ask the question. Every result carries the exact source URL to the original document at the publisher, so answers stay verifiable.

The MCP server is one of two access modes within Moonlit Connect. The other is the Moonlit Data API, for embedding the data layer into your own product.

How access works

Individuals sign in with their Moonlit account when connecting a client; no key is involved. Organizations can additionally create MCP keys for pooled and deployed services, managed under the organization settings. See Organizations.

Usage is metered per call against your plan's monthly quota. Searches, document retrievals, and filter lookups count as one call each. get_account_status and convert_to_celex are computation tools and never count. Check your remaining quota any time by asking your assistant to call get_account_status.
