1MORE Storefront Agent Commerce (UCP/MCP)
The agent-facing commerce interface 1MORE serves from its own US storefront host. A Universal Commerce Protocol merchant profile at /.well-known/ucp declares the supported UCP versions, services and payment handlers under merchant name "1MORE"; a remote MCP endpoint at https://usa.1more.com/api/ucp/mcp answers tools/list anonymously with 13 tools (catalog search/lookup/product detail, cart, checkout and order) carrying real JSON Schema 2020-12 input schemas. Read-only product JSON is available at /products.json and /collections/{handle}/products.json. The implementation is Shopify's UCP/MCP stack operating under 1MORE's domain and merchant identity; checkout requires contemporaneous buyer approval.
