notes: Livsn Designs runs no first-party MCP server, but its Shopify storefront exposes a live Universal
  Commerce Protocol (UCP) shopping MCP endpoint for agent-driven commerce. Discovered via /.well-known/ucp
  and documented in /llms.txt. A tools/list probe requires an agent profile URI, so the tool list below
  is transcribed from the store's published /llms.txt agent flow (verbatim tool names) rather than fabricated.
