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 Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-uk-caselaw). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 6 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 (good).Pass
- Context-footprint check failed: tool/resource definitions use about 780 tokens (~260/item across 3 items; 3 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 Management23
- Stability observed for 7 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 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
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
get_uk_judgment ~169
Fetch the FULL TEXT of a UK judgment from its neutral citation ("[2023] UKSC 42", "[2026] EWHC 1996 (Comm)") or its Find Case Law identifier. Returns the judgment text along with the case name, court, date and citation, so a quoted passage or a cited authority can actually be checked against what the court wrote rather than taken on trust. Text is long; use max_chars to bound it.
| Name | Type | Req | Description |
|---|---|---|---|
| citation | string | yes | Neutral citation, e.g. "[2023] UKSC 42", or a Find Case Law identifier like "uksc/2023/42". |
| max_chars | number | – | Maximum characters of judgment text to return (default 40000). The response says whether it was truncated. |
No output schema declared.
No examples provided.
list_uk_courts ~89
List the UK courts and tribunals covered by Find Case Law with the court code each one uses. Call this before narrowing search_uk_caselaw by court — a code like "ewhc/comm" cannot be guessed from "Commercial Court". Every code here has been probed live against the atom feed; an unlisted code is rejected as invalid_arguments rather than sent upstream.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_uk_caselaw ~465
Search UK court judgments and tribunal decisions by subject, party name or judge — the Supreme Court, Court of Appeal, High Court, Court of Protection, Family Court, Employment Appeal Tribunal and the other UK tribunals, from The National Archives' Find Case Law. Returns the case name, the NEUTRAL CITATION ("[2026] EWHC 1996 (Comm)"), the court, the judgment date and a link, plus the identifier get_uk_judgment reads to fetch the full text. Use this for England & Wales and UK-wide law. NOT ALL UK LAW: no Crown/County/Magistrates' Court judgments (given orally, never transcribed), no dockets/pleadings/filings, Scotland and Northern Ireland's own court systems are not covered, the first-tier Employment Tribunal is not covered (EAT appeals only), there is no citator/treatment signal, and coverage is mostly 2001 onward — a 0-row result means "not found here", not "does not exist". Per-query pass-through only, one judgment at a time: Find Case Law's Open Justice Licence excludes bulk or computational extraction across its records. US case law is a different corpus entirely — search_case_law and find_case cover that, and returning a US authority for a UK question is a wrong answer, not a near miss.
| Name | Type | Req | Description |
|---|---|---|---|
| court | string | – | Court code to narrow to, e.g. "uksc", "ewca/civ", "ewhc/comm". Call list_uk_courts for the codes — they are not guessable from a court name. |
| from_date | string | – | Earliest judgment date, YYYY-MM-DD. |
| judge | string | – | Judge name to match. |
| limit | number | – | Judgments to return, 1-50 (default 20). |
| order | string | – | newest (default) | oldest | relevance. |
| party | string | – | Party name to match, e.g. "Tesco". |
| query | string | – | Free-text search over the judgment text, e.g. "unjust enrichment" or "vicarious liability". |
| to_date | string | – | Latest judgment date, YYYY-MM-DD. |
