Shopify will let AI agents finish your online checkout for you.
The company is expanding its support for WebMCP, a protocol that lets AI agents read and interact with a website's tools, to cover the checkout flow itself. Under the update, a browser-based AI agent can now update order details, like shipping address or item quantity, and complete a purchase on a shopper's behalf. Shopify says the agent still needs the buyer's authorization before a purchase goes through. The change effectively turns checkout into an API that bots can drive, not just a form a human fills in.
Checkout has been the last mile e-commerce automation couldn't touch, because it involves money and legal consent, not just browsing. Letting an agent execute a purchase, even with a human sign-off, is a bet that shoppers will trust software to handle payment details they used to type in themselves. It also puts pressure on Shopify's competitors to open similar doors or risk agents simply skipping their stores.
Every 'agentic commerce' pitch this year has promised the same thing: less clicking, more delegating. Shopify is just the first big platform to point that delegation directly at the buy button.
