## 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 2026-08-03.

- **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 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.
  - 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**: 64/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 546 tokens (~182/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**: 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**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `lookup_retailer` (~94 tokens)

Look up verified deals and store policies for a specific online retailer: signup/newsletter offer, free-shipping threshold, return window, price-match, gift cards, student/military discounts, current sale, and the value.us VUS score (our data-confidence rating). Input a store name or domain.

Input parameters:

- `retailer` (string, required): Store name or domain, e.g. 'Brooklinen' or 'brooklinen.com'.

### `find_deals` (~141 tokens)

Find online retailers that currently have a specific kind of verified deal or policy, ranked. Use for questions like 'who has free shipping', 'which stores give a student discount', or 'what's on sale now'.

Input parameters:

- `country` (string): 2-letter market the shopper is in (e.g. 'US', 'GB', 'DE'), so results are relevant to where they can buy. Defaults to 'US'. Pass 'all' for every market. Retailers with no declared market are always i…
- `intent` (string, required): The deal/policy type to find retailers for.
- `limit` (integer): Max results (default 10).

### `check_retailer_trust` (~88 tokens)

Get value.us's proprietary VUS score (0-5) for a retailer and when its data was last verified. The VUS score measures how much current, verified data value.us holds on the store (a data-confidence signal) - it is NOT a verdict on whether the store is trustworthy or safe to buy from.

Input parameters:

- `retailer` (string, required): Store name or domain.
