## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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 2026-09-25.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 78/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 708 tokens (~141/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the RegEvidenceHub Taxi MCP server?

RegEvidenceHub Taxi is a hosted endpoint at https://taxi.regevidencehub.com/ai/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (5)

### `taxi_phv_info` (~97 tokens)

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.

### `list_supported_authorities` (~84 tokens)

Free coverage-discovery tool. Use when the user asks which councils or licensing authorities are supported, whether a named authority is covered, or when the authority name should be normalized before another call. It returns supported authority names and does not assess eligibility. After selecting one authority use taxi_licence_preflight; for two or more authorities use compare_licensing_requirements.

### `licensing_source_status` (~137 tokens)

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. For one-authority readiness use taxi_licence_preflight; for cross-authority comparison use compare_licensing_requirements.

Input parameters:

- `authority`: Exact supported licensing-authority name returned by list_supported_authorities. Omit this parameter for a global source-health and review-readiness check.

### `taxi_licence_preflight` (~144 tokens)

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. Do not use for multiple-authority comparison; use compare_licensing_requirements instead.

Input parameters:

- `payload` (object, required): One-authority applicant/fleet preflight facts. Start by calling list_supported_authorities and use the returned authority name exactly. Additional authority-specific facts are allowed and are evaluat…

### `compare_licensing_requirements` (~138 tokens)

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. Do not use for a single-authority readiness check; use taxi_licence_preflight instead.

Input parameters:

- `payload` (object, required): Cross-authority comparison request. Call list_supported_authorities first, then supply one or more exact authority names plus the applicant facts to compare. Additional applicant facts are allowed so…

### Is the RegEvidenceHub Taxi MCP server safe to use?

RegEvidenceHub Taxi scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the RegEvidenceHub Taxi MCP server expose?

RegEvidenceHub Taxi exposes 5 tools: taxi_phv_info, list_supported_authorities, licensing_source_status, taxi_licence_preflight, compare_licensing_requirements. Their descriptions and schemas cost roughly 600 tokens of context every time the server is loaded.

### Does the RegEvidenceHub Taxi MCP server require authentication?

No. We connected to RegEvidenceHub Taxi without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the RegEvidenceHub Taxi MCP server still maintained?
