## 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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 913 tokens (~228/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**: 63/100
  - Stability observed for 19 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 97/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 91% of tool parameters carry a description.
  - Structured output schemas are declared (50% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - 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.

## MCP tools (4)

### `search_cards` (~168 tokens)

Search card prices

Find a sports or trading card and its current sold price. Describe the card the way a collector would, for example "1989 Upper Deck Ken Griffey Jr 1", "2018 Topps Update Acuna US250" or "Charizard Base Set". Returns up to 5 matching cards with the raw (ungraded) and PSA 10 price, a card_id, and the link to the card page. Use get_card_prices for every grade of one card. Needs a HobbyCardIndex API key.

### `list_plans` (~176 tokens)

Commercial API plans and prices

The HobbyCardIndex plans a user can buy right now: the Commercial API sizes (requests, photo scans, sold-sale lookups, cert lookups) and the app plans Pro, Dealer and Enterprise (scans a month, dealer tools, API key on Enterprise), with monthly prices in US dollars, the terms and how to buy. Pass use_case to get the size and add-ons that fit what the user wants to do. Works without an API key.

Input parameters:

### `start_checkout` (~293 tokens)

Buy a Commercial API plan

Start buying a Commercial API plan for the user. Returns a Stripe checkout_url where the user pays by card (HobbyCardIndex never sees the card) and a status_url that returns the API key once, after payment. Only call this after the user has picked a plan from list_plans and agreed to the terms (accept_terms: true). Use the user's own email: the receipt and the account sign-in go there. Works without an API key.

- `with_price_files` (boolean): Optional, growth_lite or growth only: add the daily price files ($450 a month), a daily download of current prices for the whole catalogue. Use it when the user wants to keep their own copy of the pr…

### What did VerifyMCP test on the HobbyCardIndex Card Prices MCP server?

VerifyMCP ran 13 checks on HobbyCardIndex Card Prices, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
