Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

get_ufc_card_evidenceRead the saved estimate and recent recorded sales for one exact UFC card version identified by its catalogue cardId. Prices are USD. The estimate pools raw and graded sales and is not a physical-copy or grader-specific appraisal. Returns dates, known sale sources, a history trunc
get_ufc_card_comparablesRead up to eight selected comparable sales for an identified UFC card version, including match reasons and differences. Comparisons may include other parallels, releases or fighters. Related editions are not exact-card sales. Returns partial and unavailable status when applicable

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
