Shopify opens checkout to browser-based AI agents

While some retailers are blocking AI agents from making purchases on users' platforms, e-commerce platform Shopify has moved in the opposite direction. The company announced that browser-based AI agents can now complete purchases on Shopify merchants' sites, extending their capabilities beyond just searching for products and adding items to carts. Shopify previously supported WebMCP for storefronts and carts, allowing agents to comb through inventory and search for products. The addition of WebMCP support for checkout, including Shop Pay, means these agents can now read the checkout screen, update it, and submit transactions with buyer authorization without relying on screenshots or web scraping. This update introduces three new tools that allow agents to inspect a checkout, change customer addresses or delivery options, and place orders after buyer authorization. The feature is rolling out to all eligible Shopify merchants, leveraging Shopify's Universal Commerce Protocol (UCP) to provide a common way to manage the entire shopping lifecycle.
