Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ufc

get_ufc_card_comparables

Read 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.

get_ufc_card_evidence

Read 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 truncation flag and an Octagon link. Missing estimates remain missing.

search_ufc_cards

Search Octagon's UFC catalogue by fighter, year, release, card number, parallel or print run. Returns matching edition IDs and links for card identification before a value lookup. A query can match several editions. Does not identify uploaded photos or search other sports.

Octagon Cards — questions

Answers built from our own checks of this server.

What can Octagon Cards do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_ufc_card_comparables, get_ufc_card_evidence, search_ufc_cards. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Octagon Cards working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 89 checks got a reply (100.0%), average response time 282 ms. The bar chart above shows every period we have measured.

How do I connect Octagon Cards?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Octagon Cards need an API key?

No. Octagon Cards completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Octagon Cards?

It answers our handshake in 282 ms on average, which is faster than 50% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
