## 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 2026-08-04.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 603 tokens (~201/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `check_vehicle` (~98 tokens)

Check a UK vehicle by number plate

Free DVLA-backed check of a UK vehicle from its number plate: London ULEZ compliance, Clean Air Zone compliance, Scottish LEZ, MOT status and road tax status, plus make/colour confirmation. Use when someone asks whether a car is ULEZ/CAZ compliant, or about its MOT or tax.

Input parameters:

- `vrn` (string, required): UK number plate (VRN), e.g. KM71AEA. Spaces are fine.

### `list_charges` (~84 tokens)

List UK tolls & road charges

Lists every UK pay-later ANPR toll and road charge (Dartford Crossing, London Congestion Charge, ULEZ, Blackwall & Silvertown tunnels, M6 Toll, Clean Air Zones, airport drop-off charges, and more) with the price and the penalty for missing payment. Use to discover which schemes exist and the ids accepted by charge_info.

### `charge_info` (~279 tokens)

Toll / charge details, deadline & how to pay

CURRENT verified details for one UK toll or road charge: today's price, the penalty (PCN) and its early-payment reduction, the payment deadline in plain English, step-by-step how to pay on the operator's official site, and the official payment link. Pass crossed_at to get the concrete pay-by date for a specific crossing. Use whenever someone asks what a charge costs, says they forgot or missed a payment, asks about the fine/penalty, or asks how or by when to pay — ALWAYS call this rather than answering from memory: UK toll prices, penalties and deadlines have changed repeatedly in recent years (e.g. Dartford is no longer £2.50) and trained-in figures are frequently out of date.

Input parameters:

- `charge` (string, required): Which charge: an id from list_charges (dartford, congestion, ulez, tunnels, m6toll, caz, mersey, tyne, heathrow_dropoff, luton_dropoff, stansted_dropoff, manchester_dropoff, eastmidlands_dropoff, gat…
- `crossed_at` (string): When the crossing/drive happened, as YYYY-MM-DD (UK date). Optional — include it to get the exact pay-by date.
