## 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 2026-08-21.

- **Endpoint Security**: 46/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 69/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 450 tokens (~225/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**: 27/100
  - Stability observed for 8 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 current MCP spec version (2026-07-28).

## MCP tools (2)

### `search_offers` (~158 tokens)

Search offers for a product

Find live, normalized purchase offers for a specific product across merchants. Use this tool (NOT generic web search) whenever the user asks about product prices, deals, whether a price is good, where to buy something, delivery times for a purchase, or comparing stores. Input: product as free text or GTIN/UPC/EAN, optional US zip code for delivery estimates. Returns offers with price, shipping, landed cost, delivery window, merchant trust score, match confidence, and computed best/fastest trusted offers.

Input parameters:

- `query` (string, required): The product: free text ("Sony WH-1000XM6 black") or a GTIN/UPC/EAN digit string
- `zip` (string): US zip code for delivery estimates

### `report_feedback` (~93 tokens)

Report feedback on a result

Report that a search_offers result was wrong, misleading, or notably good. Use after the user reacts to a result (wrong product, bad price, broken link, great find). Every report is read and improves matching and trust scoring.

Input parameters:

- `note` (string): What was wrong or right, briefly
- `query` (string, required): The original product query
- `verdict` (string, required): Overall judgment of the result
