Shopify lets AI agents complete purchases at checkout

Shopify has extended WebMCP support to its checkout process, allowing browser-based AI agents to complete purchases on behalf of buyers. Three new tools — get_checkout, update_checkout, and complete_checkout — let agents inspect and modify checkout details, then submit orders after buyer authorization, without relying on screenshots or page scraping. The update, rolling out to all eligible Shopify merchants, builds on existing WebMCP support for storefronts and carts. Shopify also announced a new partnership with AI agent Instinct today. The move contrasts with retailers like Amazon, which are blocking AI agents from making purchases on their platforms.
