A reference implementation of the five canonical commerce tools Semore believes every agent-ready storefront should expose: product search across K-beauty, fashion, and pop categories; single SKU detail lookups with HS codes and lead times; cart creation with destination-aware quotes that break out shipping, duty, and import tax; pre-checkout requotes that return a signed CartMandate verifiable credential; and AP2 IntentMandate submission that hands back a checkout URL plus PaymentMandate. Ships as both a working MCP server you can npx straight into Claude Desktop and a schema-only package for validating your own integration against the spec. Semore runs the production version at mcp.semore.net and provides companion adapters for ACP, AP2, and UCP protocols.
