MCP SERVERFind a Dutch ruling by court, field of law and date, pull its full text by ECLI, and see what cites it.
LABSCO SUMMARY
That single fact shapes the whole workflow: list_waardelijsten hands over the instantie and rechtsgebied identifiers, search_uitspraken narrows on those facets and on dates, and only then does get_uitspraak or get_uitspraken_bulk fetch text. search_uitspraken_bulk carries the same warning — non-ECLI terms fall back to facet-only results. The behaviour worth noting is what happens on a miss: an ECLI with no body text is reported as such rather than filled in, and lido_related draws on a second source, KOOP's LiDO, so a ruling's standing can be judged rather than only its content read.
A Dutch case-law server over the official Rechtspraak Open Data API, exposing 6 tools for faceted search, single and batch retrieval of decisions, the value lists the filters are built from, and the LiDO citation graph.
No credentials are configured; the decisions come from the official Open Data API and the citation graph from KOOP's LiDO service.
One command — npx rechtspraak-mcp
USE CASES
Resolve the ECLI straight to its body and metadata, or take metadata alone when only the court and date are in question.
Fetch the identifiers the API will accept, then filter on them rather than guessing at names.
Read the citation graph in both directions with its Dutch relation labels, then open the decisions that turn out to matter.
Hand over the whole batch and get a result or an error per identifier, instead of a call each.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
get_uitspraakFetch the full text and metadata of a single Dutch court decision by ECLI, from the official Open Data API (data.rechtspraak.nl). Returns metadata (court, date, rechtsgebied, zaaknummer), the plain-text body, formal relations (conclusie/cassatie/etc.), and links to the ruling on rechtspraak.nl plus a PrudAI viewer. If the ECLI is not published or has no body text, the tool says so — do not invent or cite it in that case.
get_uitspraken_bulkFetch multiple Dutch court decisions by ECLI in one call (1–10 ECLIs) from the official Open Data API. Returns a per-ECLI result with the body text, metadata, relations, and links — or an error for any ECLI that is unpublished or not found.
lido_relatedGet the LiDO citation graph around a Dutch ECLI: rulings that cite it or are cited by it, referenced statute articles, and official publications, with typed Dutch link labels (e.g. 'Verwijst naar', 'Conclusie', 'Vernietigt'). Data comes from KOOP's live LiDO service (linkeddata.overheid.nl). Use it to position a ruling (is it a landmark? what does it cite?). Read-only and bounded (per-direction limit default 100, max 250). This returns structure, not full text — use get_uitspraak for the text of any neighbour.
list_waardelijstenList the Rechtspraak value lists (waardelijsten) used to build valid search filters: instanties, instanties_buitenlands, rechtsgebieden, proceduresoorten, niet_nederlandse_uitspraken. 'rechtsgebieden' and 'instanties' return the identifiers/URIs you pass to search_uitspraken (rechtsgebied / instanties). Call without a name to see the available lists.
search_uitsprakenSearch Dutch case law (jurisprudentie/uitspraken) via the official Open Data API and get back ECLIs with links to the ruling and a PrudAI viewer. This is a faceted search: filter by rechtsgebied, instantie, date range and document type. It does not do free-text keyword matching. If you already have an ECLI, pass it as query and the tool returns that single decision's summary. Use list_waardelijsten to discover valid rechtsgebied/instantie identifiers.
search_uitspraken_bulkRun several Open Data lookups at once (3–10 entries). Pass ECLIs to resolve a batch of decisions' summaries in one call. Note: Open Data has no free-text matching, so non-ECLI terms fall back to facet-only results — prefer get_uitspraken_bulk when you already have the ECLIs. Use to cast a broad net before narrowing down via get_uitspraak.
BEFORE YOU INSTALL
6 tools when we connected. search_uitspraken filters by date, court, legal area and document type rather than free text; pass an ECLI to look up a decision directly. Bulk tools return up to 10 decisions per call.
npx on PATH
Both documented clients run the server on your machine.
