Rhone UCP Commerce (MCP)

Rhone's agent-facing commerce surface, implementing the Universal Commerce Protocol over MCP (JSON-RPC 2.0). Thirteen tools cover catalog search and lookup, product detail, cart create / update / cancel, checkout create / update / complete / cancel, and order read. tools/list is anonymous and returns full JSON Schema inputSchemas; tools/call requires a resolvable UCP agent profile URI, and complete_checkout additionally requires an idempotency key. Rhone's own robots.txt and llms.txt state that payment must never be completed without contemporaneous human approval. Platform-provided by Shopify, served from Rhone-controlled hosts and scoped to Rhone's own catalog and orders.
