What this server can do

7 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

eurlex_browse_subjects(limit, offset, keyword, language)
Search the EuroVoc thesaurus, resolving a keyword into concept URIs usable in the eurovoc_concept subject filter of eurlex_search_documents. Returns each concept URI, its preferred label in the requested language, code, and broader (parent) label, ordered alphabetically by label. Required: keyword.
eurlex_get_cases(court, limit, offset, date_to, keyword, case_type, date_from, case_number, include_derivative)
Search CJEU and General Court case law — judgments, orders, and Advocate General opinions — by case number, court, case type, keyword, and date range. By default only these primary records are returned; derivative judicial information notices, case abstracts, summaries, and corrigenda are excluded so distinct cases fill the page (set include_derivative to include them). Keyword matches English case titles (which carry party names) and CELEX strings; there is no full-text body search. Returns each case with its court, date, and type, plus — parsed from the title where present — the parties, subject matter, and case reference.
eurlex_get_document(limit, format, offset, select, eli_uri, outline, resolve, language, work_uri, celex_number, content_mode)
Fetch the metadata and full text of an EU act by CELEX number, ELI URI, or work URI. Returns structured metadata (title, date, type, author institution, legal basis, EuroVoc subjects, in-force status) plus the act body as HTML, Markdown, or Formex4 XML, defaulting to English with automatic fallback. Large bodies are paged by default (offset/limit with has_more) or returned whole with content_mode "full"; use outline: true for a heading map and select to pull specific articles, chapters, recitals, or annexes.
eurlex_get_relations(limit, offset, work_uri, celex_number, relation_types)
Traverse the one-hop CDM relationship graph of an EU act: what it amends or is amended by, what it repeals or is repealed by (explicit and implicit), its consolidated versions, its legal basis, and works that cite it. Returns direct relations only, paginated per relation type and direction. Requires a CELEX number or CELLAR work URI.
eurlex_lookup_celex(identifier, identifier_type)
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. Returns the work URI, confirmed CELEX number, document type, and date. Required: identifier.
eurlex_query_sparql(sparql_query, timeout_hint)
Run a raw, read-only SPARQL SELECT against the CELLAR Virtuoso endpoint — an escape hatch for CDM ontology traversals the curated tools do not cover. Only SELECT is accepted; update forms and ASK/CONSTRUCT/DESCRIBE are rejected before execution, and results are capped at 100. The cdm:, skos:, and xsd: prefixes are auto-injected. Required: sparql_query.
eurlex_search_documents(limit, offset, date_to, keyword, in_force, date_from, document_type, eurovoc_concept, author_institution, include_consolidated)
Search EU legislation, treaties, and preparatory acts across the CELLAR corpus by document type, date range, EuroVoc subject, author institution, and in-force status. Keyword matches English titles and CELEX strings only — there is no full-text body search. Returns a page of CELEX numbers, work URIs, type labels, dates, and titles, newest first, each flagged with is_consolidated. At least one filter is required.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

Signal Value What it measures Window Observed Source
GitHub stars 5 Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. cumulative, all time GitHub
Last commit 2026-07-30 Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. point in time GitHub
Open issues 7 Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. as of fetch GitHub

Where to get it

Related, by what their authors tagged them

These share tags the maintainers applied themselves, such as eu-law, cyanheads, sparql, legislation. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
