Hero Bread Storefront Agent Commerce (UCP/MCP)
The agent-facing commerce interface for the Hero Bread online store. An MCP server at https://shop.hero.co/api/ucp/mcp implements the Universal Commerce Protocol shopping service (dev.ucp.shopping) with thirteen tools spanning catalog search and lookup, cart create/read/ update/cancel, checkout create/read/update/complete/cancel, and order read. tools/list answers anonymously; tools/call requires a resolvable UCP agent profile and, for transactional tools, a Shopify agent JWT. complete_checkout requires an idempotency key and, per the store's own published rules, explicit contemporaneous buyer approval before payment.
