Shopify enables AI agents to complete purchases on browser-based platforms
Shopify is expanding the capabilities of browser-based AI shopping assistants by allowing them to complete checkout processes for its merchants. Previously, these agents could only search and add items to carts using WebMCP (Web Model Context Protocol). Now, with support extended to checkout—including Shop Pay—agents can read, update, and submit transactions after buyer authorization without relying on screenshots or page scraping. The new tools introduced are get_checkout, update_checkout, and complete_checkout. These APIs allow AI agents to modify customer details like address or delivery options before finalizing an order. The feature is being rolled out to all eligible Shopify merchants as part of the company’s broader push into agentic commerce through its Universal Commerce Protocol (UCP). Top AI shopping assistants such as Muse and Instinct already partner with Shopify, including a new partnership announced alongside this update. Shopify's hosted MCP server allows agents to operate server-to-server while WebMCP is designed for browser-based interactions. The company emphasizes that these tools are structured to ensure accurate commerce data and compliance requirements.
