AI Agents in E-Commerce

While some retailers, like Amazon and Adidas, are blocking artificial intelligence agents from making purchases on users’ behalf on their respective platforms, e-commerce platform Shopify has moved in the opposite direction.

The company announced that browser-based artificial intelligence agents can now complete purchases on Shopify merchant sites, extending their capabilities beyond just searching for products and adding items to carts.

WebMCP Integration

Shopify previously supported WebMCP for its storefronts and carts, allowing browser-based AI agents to comb through a Shopify retailer’s inventory, search for products, and add them to a cart. The addition of WebMCP support for checkout, including Shop Pay, means these agents can now read the checkout screen, update it, and submit the transaction with the buyer’s authorization, without relying on screenshots or scraping webpages.

New Checkout Tools

This update introduces three new tools — get_checkout, update_checkout, and complete_checkout — that allow agents to inspect a checkout, change parameters like the customer’s address or delivery option, and then place an order after the buyer authorizes it.

The feature is rolling out to all eligible Shopify merchants, said Gil Greenberg, a staff product manager who works on agentic commerce at Shopify.

Protocols and Standards

Shopify already offers a hosted Model Context Protocol server, which allows agents to work server-to-server. The proposed standard WebMCP, meanwhile, is designed for agents that work inside the buyer’s browser. Both leverage Shopify’s Universal Commerce Protocol, which provides a common way to search for and discover products, build carts, and check out.

Industry Partnerships

Artificial intelligence agents like Muse and Instinct already have direct partnerships with Shopify for agentic commerce.

If an agent is operating in the buyer’s browser, developers can use WebMCP tools provided on storefront and checkout to efficiently complete order placement, instead of navigating HTML built for humans. These WebMCP tools provide structured and efficient APIs designed via the Universal Commerce Protocol to ensure accurate commerce facts, required disclosures, and handoff requirements.
