notes: august.com (a Shopify-hosted storefront for August Home / Yale smart-lock hardware) publishes a
  live, hosted Model Context Protocol server for agent-driven commerce via the Universal Commerce Protocol
  (UCP, https://ucp.dev). The server is advertised in the store's /llms.txt agent instructions and in
  the /.well-known/ucp merchant profile under the dev.ucp.shopping service. It is a commerce/shopping
  MCP (search, cart, checkout) for the storefront, NOT a device or smart-lock control API. A raw tools/list
  call returns HTTP 422 until the agent completes UCP profile discovery, so the tool list below is transcribed
  from the store's published /llms.txt agent flow and the UCP dev.ucp.shopping capability set (checkout,
  cart, fulfillment, discount), not from a live tools/list dump.
