Willow's storefront agent surface — a JSON-RPC 2.0 Model Context Protocol endpoint implementing the Universal Commerce Protocol 2026-08-25 shopping service. tools/list answers unauthenticated and returns 13 tools with full JSON Schema 2020-12 input schemas: search_catalog, lookup_catalog and get_product for the catalog; create/get/update/cancel_cart and create/get/update/complete/ cancel_checkout for the purchase flow; and get_order behind a signed agent JWT. Every tools/call requires a resolvable UCP agent profile URI, complete_checkout requires an idempotency key, and payment requires explicit buyer approval. The runtime is Shopify's universal-commerce server running under Willow's own domain and transacting Willow's own catalog.
