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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability30
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (fair).Partial
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

appraise_vehicle TradeBasis US market appraisal ~488
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |

| 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. |
