## 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 2026-11-05.

- **Endpoint Security**: 80/100
  - 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.
  - 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**: 30/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Context-footprint check failed: tool/resource definitions use about 495 tokens (~247/item across 2 items; 1 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 87/100
  - Stability observed for 26 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

## MCP tools (1)

### `appraise_vehicle` (~488 tokens)

TradeBasis US market appraisal

A derived TradeBasis asking-price market average. Supply odometerMiles plus either vin or all of year, make, model and trim. Ask the user for missing details; never invent vehicle identity or mileage. VIN-assisted decoding may still require a confirmed trim, fuelType or bodyStyle. If supplied identity conflicts with the VIN, ask the user to verify the VIN and conflicting fields; do not choose silently or retry unchanged. Omit market for nationwide US. Not a trade-in offer or completed-sale value.

Input parameters:

- `bodyStyle` (string): Optional confirmed body style: sedan, hatchback, coupe, convertible, SUV, pickup, wagon, minivan or van. Required later if identity is ambiguous; ask the user and do not contradict the VIN.
- `fuelType` (string): Optional confirmed powertrain/fuel type. Required later if identity is ambiguous. Ask the user rather than selecting a default; must agree with a reported VIN powertrain.
- `make` (string): Confirmed vehicle manufacturer. Required without vin; optional with vin, but must agree with the decoded make.
- `market` (string): Optional US state name or two-letter state code, not the user's precise location. Omit for nationwide US.
- `model` (string): Confirmed US model name. Required without vin; optional with vin, but must agree with the decoded model.
- `odometerMiles` (number, required): Current odometer reading in miles, required for BOTH input paths. Ask the user; never estimate mileage from the VIN or model year. Zero is valid only when actually reported.
- `trim` (string): Confirmed exact trim, including meaningful +, hyphens and powertrain qualifiers. Required without vin. With vin, supply it if decoding does not identify one unambiguous trim; never assume Base or cho…
- `vin` (string): VIN-assisted input: provide the vehicle's 17-character VIN with odometerMiles. Optional for complete manual input. Decoding may leave trim, fuelType or bodyStyle unresolved; ask the user to confirm t…
- `year` (integer): Confirmed model year. Required without vin; optional with vin, but must agree with the decoded year. Ask the user if unknown.

Output parameters:

- `actualMarket` (string): Geography reported for the selected evidence; unknown listing states are explicitly identified.
- `automaticRetryAllowed` (boolean): Recoverability never authorizes automatic paid searches.
- `baseMarketAverage` (integer)
- `calculatedAt` (string)
- `clarificationFields` (array)
- `currency` (string)
- `evidenceCount` (integer)

- `requestedMarket` (string)
