  honest.com implements the Universal Commerce Protocol (UCP, https://ucp.dev)
  and exposes a live hosted MCP endpoint for agent-driven commerce. The endpoint
  responds to JSON-RPC over HTTP POST (verified live: it returns structured
  JSON-RPC errors). A full tools/list enumeration requires a valid UCP agent
  profile URI in the request, so the tool surface below is transcribed from the
  provider-published /agents.md typical-agent-flow and the /.well-known/ucp
  capability list rather than from a completed tools/list handshake. This MCP
  server is provided by the Shopify UCP platform on the honest.com domain.
