The 7 tools this server offers to Kahubi. The assistant picks the right one for each question.

    Resolve an EU legal citation - a CELEX number or ELI URI - to its canonical CELLAR work, confirming it exists before you fetch or traverse it.

  • eurlex_browse_subjects

    Search the EuroVoc thesaurus, resolving a keyword into concept URIs usable in the eurovoc_concept subject filter of eurlex_search_documents.

  • eurlex_search_documents

    Search EU legislation, treaties, and preparatory acts across the CELLAR corpus by document type, date range, EuroVoc subject, author institution, and in-force status.

  • eurlex_get_document

    Fetch the metadata and full text of an EU act by CELEX number, ELI URI, or work URI.

  • eurlex_get_relations
