| Tool | What it does |
|---|---|
search_uitspraken | Search case law (faceted by default; full-text behind a flag). Returns ECLIs + links. |
search_uitspraken_bulk | Run 3–10 searches at once. |
get_uitspraak | Fetch full text + metadata + relations of one decision by ECLI. |
get_uitspraken_bulk | Fetch up to 10 decisions by ECLI in one call. |
list_waardelijsten | List value lists (instanties, rechtsgebieden, proceduresoorten, …) to build valid filters. |
lido_related | LiDO citation graph around an ECLI: what cites it, what it cites, statute references. |
search_uitspraken is a faceted search over the official Open Data feed — filter by date, court (instantie), legal area (rechtsgebied) and document type. It does not do free-text keyword matching; pass an ECLI to query for a direct lookup, or use the facet filters. get_uitspraak fetches the full text and metadata from the documented Open Data content endpoint.
Claude Code (or any client reading claude_desktop_config.json / .mcp.json):

Every result carries links for its ECLI:
