  Fnatic serves one live MCP endpoint from its own shop host: the Universal Commerce
  Protocol (UCP) shopping service at https://shop.fnatic.com/api/ucp/mcp. It is
  advertised in Fnatic's own /agents.md and /llms.txt and in the UCP merchant profile at
  /.well-known/ucp. An anonymous tools/list is GATED — it returns JSON-RPC error -32001
  "UCP discovery failed" (invalid_profile_url, "Missing profile uri"), so the agent must
  present a UCP agent profile URI before the tool list is enumerable. The Shopify
  Storefront MCP server at /api/mcp is NOT enabled on this shop (404). No MCP surface
  exists on fnatic.com itself.

        Names below are taken verbatim from the "Typical Agent Flow" section Fnatic
        publishes in its own /agents.md and /llms.txt. Their input schemas require an
        authorized UCP tools/list call and are deliberately NOT recorded here — nothing
        about their parameters has been observed.
