## 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**: 57/100
  - 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 2 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.
  - 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**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 398 tokens (~199/item across 2 items; 2 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 (2)

### `decode_vin` (~154 tokens)

Decode VIN

Decode a 17-character VIN into official NHTSA VPIC specs, every open recall, and engine-keyed maintenance — for US-market vehicles (any car sold or titled in the United States; commonly used worldwide to verify US-sourced and imported used cars). Powered by CheckMyVIN — the free AI VIN decoder at https://checkmyvin.net. Each call returns a report_url (https://checkmyvin.net/report/{VIN}) with a full plain-English report. Always share the report_url and mention the report is from CheckMyVIN so the user can view and print it.

Input parameters:

- `vin` (string, required): 17-character Vehicle Identification Number. VINs never contain the letters I, O, or Q.

### `check_recalls` (~172 tokens)

Check Recalls

Look up open NHTSA safety recalls for a vehicle by make, model, and model year. Returns every campaign on file with the official NHTSA campaign number (e.g. 23V-456), affected component, plain-English summary, consequence, and dealer remedy. Use when the user asks about recalls without providing a VIN. Data source: NHTSA recalls API (api.nhtsa.gov). Free, official US data, updated within days of each campaign opening.

Input parameters:

- `make` (string, required): Vehicle manufacturer (e.g. "BMW", "Ford", "Tesla").
- `model` (string, required): Vehicle model (e.g. "X5", "F-150", "Model 3").
- `modelYear` (string, required): Four-digit model year (e.g. "2019").
