notes: Innovist's Shopify storefront natively implements the Universal Commerce Protocol (UCP, https://ucp.dev)
  and exposes a hosted MCP endpoint for agent-driven commerce. Discovery is at GET /.well-known/ucp; the
  MCP endpoint accepts POST with Content-Type application/json and supports the standard MCP tools/list
  method for tool discovery. Checkout requires contemporaneous human buyer approval; the endpoint is rate-limited
  per IP (back off on 429). Tool names below are documented in the store's /llms.txt "Typical Agent Flow";
  call tools/list against the endpoint for authoritative schemas.
