## 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 2026-09-28.

- **Endpoint Security**: 74/100
  - 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.
  - 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**: 63/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1017 tokens (~254/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "check_price_drop_claim" implies "drop" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 5 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.

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

With an item name it adds links to check today's price

Input parameters:

Can I get the difference back?

Can I get the difference back?. Use for "I bought a TV at Best Buy 9 days ago for $499 and it's $449 now, can I get the difference?". Says whether a claim is likely (likely, likely_if_member, unlikely, check or no_drop), the amount, and the steps. With an item name it adds a Cheapest Price link and Amazon and eBay links to check today's price. Likely claims also get claim_message, ready to paste into the store's chat or email. policy.refund_paid_as flags stores that pay store credit (Newegg)

Input parameters:

- `country` (string): Two-letter country code. GB (or UK) gives the UK policy where the store has one (Apple, Amazon, IKEA) and UK rules; it also picks the price links (US, GB and IE get local Amazon and eBay links). Defa…
- `days_since_purchase` (integer): Days since you bought it (or since delivery), 0 to 400. Give this or purchase_date.
- `item` (string): Optional item name, up to 100 characters, to link today's price on Cheapest Price, Amazon and eBay.
- `now` (number): Today's price, 0 to 100000 (US dollars, or pounds for UK stores).
- `paid` (number): What you paid, 0 to 100000 (US dollars, or pounds for UK stores).
- `purchase_date` (string): The date you bought it, YYYY-MM-DD, instead of days_since_purchase. Adds deadlines: the last day to claim with the store (and in a members' longer window) and Capital One card protection.

Nothing is stored. /v1/check gives this link as add_to_calendar when purchase_date is given and a claim is likely
