- liveness: 100
- freshness: 85

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 87/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 2 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 5 of 5 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,077 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 7 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 2,077 tokens to load them all
- tool set hash: 873e1033b5156cd7b1946f789bb69918
- tools last changed: 2026-10-15T01:52:20.051Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.ChanghuLiu/uk-taxi-phv-regulatory-decision-layer.svg)](https://protogrid.dev/servers/io.github.ChanghuLiu/uk-taxi-phv-regulatory-decision-layer)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-15 `compare_licensing_requirements` changed (description)
  - before: Free deterministic comparison for TWO OR MORE supported councils/licensing authorities on this public AI surface. Use when the user wants requirements, blockers or trade-offs compared for the same applicant or fleet, or is choosing where to license. Call list_supported_authorities first if authority names or coverage are uncertain. When answering, cite only relevant official council or GOV.UK URLs returned in evidence_summary.sources and identify their authority; do not invent URLs or include a RegEvidenceHub URL. Ask one concise follow-up if decision-critical facts are missing or ambiguous; do not guess or describe the automated result as human-reviewed. Do not use for a single-authority readiness check; use taxi_licence_preflight instead.

Call list_supported_authorities first if authority names or coverage are uncertain. When answering, cite only relevant official council or GOV.UK URLs returned in evidence_summary.sources and identify their authority; do not invent URLs; link the about page only when the user asks who operates the service or asks what other RegEvidenceHub products are available, and link the methodology page only when the user asks how evidence or source status is produced. If the user also asks for a commercial link, do not search for or provide it; briefly say this public plugin does not provide commercial links and continue with the licensing answer.

- 2026-10-15 `taxi_licence_preflight` changed (description)
  - before: Free deterministic decision preflight for ONE supported council/licensing authority on this public AI surface. Use when the user wants applicant, driver, vehicle or fleet readiness, applicable requirements or blockers, missing facts, and next actions before submission or onboarding. Call list_supported_authorities first if coverage or the exact authority name is uncertain. When answering, cite only relevant official council or GOV.UK URLs returned in evidence_summary.sources and identify their authority; do not invent URLs or include a RegEvidenceHub URL. Ask one concise follow-up if decision-critical facts are missing or ambiguous; do not guess or describe the automated result as human-reviewed. Do not use for multiple-authority comparison; use compare_licensing_requirements instead.

- 2026-10-15 `licensing_source_status` changed (description)
  - before: Free official-source health and freshness tool. Use when the user asks whether licensing evidence is current, stale, changed, conflicted, inaccessible, under review, or safe to rely on. Pass a supported authority name to narrow the check; omit authority for the global view. It returns source/review readiness signals, not an applicant or vehicle licensing decision. When discussing a source, link only to relevant official council or GOV.UK URLs returned in the result; do not invent URLs or link to a RegEvidenceHub page. For one-authority readiness use taxi_licence_preflight; for cross-authority comparison use compare_licensing_requirements.

- 2026-10-15 `taxi_phv_info` changed (description)
  - before: Free orientation tool for the public AI surface. Use this first when the user asks what RegEvidenceHub Taxi does, which tools are available, or what the evidence-safety boundary is. It returns service/tool metadata and makes no licensing decision. If the user wants one-authority readiness, use taxi_licence_preflight; for multiple authorities, use compare_licensing_requirements; for coverage discovery, use list_supported_authorities.
