## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 78/100
  - No malware found by supply-chain analysis.
  - CVE check failed: a known medium-severity CVE affects fast-xml-parser 4.5.7, a direct dependency. A fixed version is available.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (97 of 101), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to Prudai/rechtspraak-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 61 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1096 tokens (~182/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (6)

### `search_uitspraken` (~323 tokens)

Search 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.

Input parameters:

- `dateFrom` (string): Uitspraakdatum from, YYYY-MM-DD.
- `dateTo` (string): Uitspraakdatum to, YYYY-MM-DD.
- `from` (integer): Zero-based pagination offset (default 0).
- `instanties` (array): Court filter: a single OWMS creator URI (find it via list_waardelijsten).
- `max` (integer): Max results to return (default 25).
- `query` (string): A single ECLI to look up directly. (Open Data has no free-text search; non-ECLI keywords are ignored — use the facet filters instead.)
- `rechtsgebied` (string): Rechtsgebied slug (e.g. 'civielrecht', 'strafrecht', 'bestuursrecht', 'internationaalpubliekrecht') or full PSI URI.
- `sort` (string): 'date' for newest-first; otherwise the API's default order.
- `type` (string): Restrict to rulings or AG conclusies.

### `search_uitspraken_bulk` (~146 tokens)

Run 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.

Input parameters:

- `from` (integer): Zero-based offset per term (default 0).
- `pageSize` (integer): Results per term (max 10, default 10).
- `terms` (array, required): 3–10 distinct search terms, phrased differently.

### `get_uitspraak` (~171 tokens)

Fetch 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.

Input parameters:

- `ecli` (string): ECLI identifier, e.g. ECLI:NL:HR:2023:1234 (alias: id).
- `id` (string): Alias for ecli.
- `metadataOnly` (boolean): When true, fetch metadata only (no body text).

### `get_uitspraken_bulk` (~103 tokens)

Fetch 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.

Input parameters:

- `eclis` (array, required): 1–10 ECLI identifiers.
- `metadataOnly` (boolean): When true, fetch metadata only (no body text).

### `list_waardelijsten` (~113 tokens)

List 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.

Input parameters:

- `name` (string): Which value list to fetch. Omit to list available names.

### `lido_related` (~240 tokens)

Get 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.

Input parameters:

- `direction` (string): 'both' (default), 'in' (only citing), 'out' (only cited).
- `ecli` (string, required): ECLI identifier, e.g. ECLI:NL:HR:2019:1278. Case-sensitive local segment.
- `limit` (integer): Per-direction edge limit (default 100).
- `linkTypeCodes` (array): Optional filter on link-type codes (e.g. ['lx-referentie', 'rvr-conclusie']).
