3N Eyecare Agentic Commerce (UCP / MCP)
The Universal Commerce Protocol shopping service 3N Eyecare exposes on its own storefront host. An anonymous JSON-RPC 2.0 MCP endpoint serves 13 tools for catalog search and lookup, cart create/update/cancel, checkout create/update/ complete/cancel and order retrieval, each with a published JSON Schema inputSchema. Checkout completion requires contemporaneous human approval, which the store states in both robots.txt and llms.txt. The runtime is Shopify's UCP implementation (serverInfo name "universal-commerce", version 0.1.0), served under the 3N Eyecare merchant identity (merchant_name "3N Eyecare", merchant_origin www.3neyecare.com).
