Tools

Seven tools the Moonlit MCP server exposes to Claude. The model picks which one to use; the lawyer just asks the question.

keyword_search

Find documents by exact words, phrases, or boolean expressions. Best when the citation, ECLI, CELEX, or article number is already known.

hybrid_search_reranked

Find documents using a natural-language question. Combines keyword and semantic search and reranks for precision. Best for conceptual research where the wording varies. Slower than keyword search; more accurate on complex questions.

reference_search

Find documents that cite a given regulation or judgment, or documents it cites. Useful for understanding how a provision has been applied across the Moonlit Data Layer.

get_filters

Return the canonical lists for jurisdictions, portals, document types, fields of law, and sources. The model uses these to scope searches accurately. Lawyers don't call this directly.

retrieve_document

Return a document's full text and metadata: title, date, jurisdiction, source, AI summary, and the source URL to the original document at the publisher. Use after a search to read or quote a document in full.

get_document_articles

Return the article-level structure of a composite document such as the GDPR or the AI Act. Used to locate a specific article inside a regulation.

convert_to_celex

Resolve an EU directive or regulation given as (year, number) to its canonical CELEX identifier. Example: (regulation, 2016, 679) returns 32016R0679, the GDPR.
