  BloomThis is a Shopify store that natively exposes a hosted MCP endpoint via the
  Universal Commerce Protocol (UCP, https://ucp.dev). The endpoint speaks JSON-RPC MCP.
  A live tools/list without a UCP agent profile URI returns 422 (invalid_profile_url),
  so the tool set below is the documented UCP shopping surface from /llms.txt and the
  UCP shopping schema (mcp.openrpc.json), not a fabricated list.
