GoKawiilShopify adds WebMCP checkout support, letting browser AI agents complete purchases
Shopify announced that browser-based AI agents can now finish transactions on merchant checkout pages, including through Shop Pay, rather than just searching products and building carts. The update adds three tools—get_checkout, update_checkout, and complete_checkout—that let agents read and modify checkout details and submit orders once a buyer authorizes it. The feature is rolling out to all eligible Shopify merchants, according to staff product manager Gil Greenberg.
GoKawiil's interpretation of the reporting above, not reported fact.
The move contrasts with retailers like Amazon and Adidas that are reportedly restricting AI agents from completing purchases, suggesting a split in how e-commerce platforms are approaching agentic shopping. By building on its existing Universal Commerce Protocol and MCP server, Shopify appears to be positioning itself as a proving ground for AI-driven checkout flows ahead of wider industry adoption. This could give Shopify merchants an early edge in capturing agent-initiated sales if the technology gains traction.
- Shopify now lets browser-based AI agents complete checkout, including via Shop Pay, not just browse and add to cart.
- New tools—get_checkout, update_checkout, complete_checkout—let agents modify checkout details and submit orders with buyer authorization.
- The rollout contrasts with other retailers reportedly blocking AI agents from making purchases on their platforms.
