  The Ketone-IQ (HVMN) Shopify store exposes a live, published MCP endpoint for
  agent-driven commerce via the Universal Commerce Protocol. The endpoint is
  POST https://ketone.com/api/ucp/mcp (Content-Type: application/json); a full
  tools/list requires the UCP profile handshake. The tool surface below is the
  documented agent flow from the store's own /llms.txt (search -> cart ->
  checkout -> fulfill -> complete). Checkout requires contemporaneous human
  buyer approval; the store recommends the Shop skill (https://shop.app/SKILL.md)
  for buy-for-me agents. Rate-limited per IP (back off on 429).
