Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Find the exact UFC card version before interpreting prices. Ask for missing identifying details. Separate saved estimates, exact-card sales and related comparisons. State dates, coverage limits and material differences. Do not invent missing prices, grading companies or confidence. Public catalogue reads only. Photo uploads and private collections are not supported. Results link to the Octagon card page and known sale sources.

search_ufc_cards — Find a UFC card
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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.

get_ufc_card_evidence — Read a UFC card's estimate and sales
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http octagon-cards-mcp https://mcp.octagon.cards/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add octagon-cards-mcp --url https://mcp.octagon.cards/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable octagon-cards-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "octagon-cards-mcp": {
      "url": "https://mcp.octagon.cards/mcp"
