Shopify opens checkout to browser-based AI agents
Shopify announced WebMCP support for checkout (including Shop Pay), allowing browser-based AI agents to inspect, update, and complete purchases on eligible merchants’ storefronts via three new tools: get_checkout, update_checkout, and complete_checkout. The change extends existing WebMCP storefront/cart capabilities and leverages Shopify’s Universal Commerce Protocol (UCP); Shopify also offers a hosted MCP server and partners such as Muse and Instinct for agentic commerce.
