Available components
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. How we score → Why this is hard to score →
Supply Chain Security82
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known advisory affects this package; its severity couldn't be graded. See how to fix → View diagnostics → Fail
- Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- 2 of 23 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 27 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability63
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 3290 tokens (~365/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management93
- Stability observed for 28 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
gb_coverage ~102
Declare what this connector covers, how it is sourced, and what it does NOT cover. Call this before telling a user that the law "does not contain" something, and whenever a search comes back empty: the absence may be a gap in this connector rather than in the law. Every gap carries a fallback saying where to look instead. Returns: ``Coverage`` with families, an as-of note, and a non-empty list of known gaps.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| as_of_note | string | yes | States what the dates mean, and what they do not promise. |
| families | array | – | – |
| known_gaps | array | – | Never empty. An empty list would mean 'not checked', not 'no gaps'. |

Fetch one GOV.UK document (tribunal decision, HMRC manual section, CMA case). Maps to the GOV.UK Content API (``www.gov.uk/api/content/{path}`` - confirmed live 2026-07-07). Tribunal decisions carry the judgment as a PDF in ``attachments`` with only a short HTML body; HMRC manual sections carry the full text in ``body_html``.

gb_recent_legislation ~189
UK legislation published since ``since_iso`` (ISO 8601 date), newest-first. Maps to the Atom search feed sorted/filtered by publication year, optionally scoped to one ``doc_type``. legislation.gov.uk's public search feed does not support a generic ``dateFrom`` filter across all types, so this tool filters the requested year's feed by the ``published`` date client-side.
| Name | Type | Req | Description |
|---|---|---|---|
| doc_type | – | – | restrict to one UK document-type code (e.g. ``"ukpga"``, ``"uksi"``). |
| limit | integer | – | max items to return (1..100). |
| since_iso | string | yes | a date in ISO 8601 (e.g. ``"2026-01-01"``). Only the year is used to select the feed to scan; items are then filtered to on/after this date. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
gb_search ~122
Search UK legislation on legislation.gov.uk. Maps to the official Atom search feed (``/all/data.feed`` or ``/{doc_type}/data.feed``, optionally with ``?text=...&year=...&page=...``). Each item gets ``eli_uri``, ``human_readable_citation``, ``source_url`` (per Art. 4 CONSTITUTION).
| Name | Type | Req | Description |
|---|---|---|---|
| query | object | yes | ``SearchQuery`` - text, doc_type (e.g. 'ukpga', 'uksi', 'asp'), year, page. |
| Name | Type | Req | Description |
|---|---|---|---|
| dataset_note | string | – | – |
| items | array | – | – |
| query_echo | – | – | – |
| total_estimate | integer | yes | – |
No examples provided.
gb_search_case_law ~244
Search UK case law on The National Archives' Find Case Law service. Maps to the public Atom feed at ``caselaw.nationalarchives.gov.uk/atom.xml`` (confirmed live 2026-07-06 - keyless, Open Justice Licence). A separate service from legislation.gov.uk: different host, different Atom dialect (``tna:`` namespace).
| Name | Type | Req | Description |
|---|---|---|---|
| court | – | – | court/tribunal code, e.g. ``"ewhc/admin"``, ``"ewca/civ"``, ``"uksc"``. Passed through to Find Case Law's own ``court`` query param. |
| from_date | – | – | ISO 8601 date (YYYY-MM-DD), inclusive. Find Case Law's public API has no documented server-side date-range filter, so this is applied client-side against each result's ``date`` field after fetching. |
| limit | integer | – | max items to return (1..100). |
| query | – | – | full-text search (matches judgment text in order, per upstream docs). |
| to_date | – | – | ISO 8601 date (YYYY-MM-DD), inclusive. Same client-side caveat. |
| Name | Type | Req | Description |
|---|---|---|---|
| dataset_note | string | – | – |
| items | array | – | – |
| query_echo | – | – | – |
| total_estimate | integer | yes | – |
No examples provided.
gb_search_govuk ~347

Maps to the GOV.UK Search API (``www.gov.uk/api/search.json`` - confirmed live 2026-07-07: keyless, Open Government Licence v3.0). One upstream aggregating many institutions; filter with ``document_type``. Legally weighty types with live-verified totals (2026-07-07): ``employment_tribunal_decision`` (132,162), ``hmrc_manual_section`` (85,315), ``residential_property_tribunal_decision`` (17,088), ``employment_appeal_tribunal_decision`` (2,571), ``cma_case`` (2,565), ``utaac_decision`` (2,031), ``tax_tribunal_decision`` (1,414), ``asylum_support_decision`` (101).

| from_date | – | – | ISO 8601 date (YYYY-MM-DD), inclusive - passed server-side via ``filter_public_timestamp`` (unlike Find Case Law, GOV.UK supports this). |
| limit | integer | – | max items to return (1..100). |
| organisation | – | – | GOV.UK organisation slug, e.g. ``"competition-and-markets-authority"``. |
| query | – | – | full-text search terms. |
