The update adds three WebMCP tools — get_checkout, update_checkout, and complete_checkout — that let agents read and modify a checkout screen and place an order after buyer authorization, without screenshots or webpage scraping, according to Gil Greenberg, a staff product manager working on agentic commerce at Shopify. The feature is rolling out to all eligible Shopify merchants, and Shopify said top AI agents Muse and Instinct already hold direct agentic-commerce partnerships with the platform.", "body_md": "While some retailers, like [Amazon](https://www.bloomberg.com/news/articles/2026-09-21/amazon-blocks-meta-s-muse-ai-agent-from-its-retail-site) (and [Adidas](https://x.com/kesslerIO/status/2104397316673462339), apparently!), are [blocking](https://x.com/kesslerIO/status/2104397316673462339) AI agents from making purchases on users’ behalf on their respective platforms, e-commerce platform Shopify has moved in the other direction. \n\nOn Monday, the company [announced](https://x.com/gilgNYC/status/2104583942728822998) 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.\n\nShopify previously supported [WebMCP](https://shopify.dev/docs/api/web-mcp) 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, the company said.\n\nThis update introduces three new tools — get_checkout, update_checkout, and complete_checkout — that allow agents to inspect a checkout, change things like the customer’s address or delivery option, and then place an order after the buyer authorizes it.\n\nThe feature is rolling out to all eligible Shopify merchants, said [Gil Greenberg](https://www.linkedin.com/in/gilgreenberg/), a staff product manager who works on agentic commerce at Shopify, in a [post on X](https://x.com/gilgNYC/status/2104583942728822998).\n\nShopify already offers a hosted [Model Context Protocol (MCP)](https://modelcontextprotocol.io/docs/2026-07-28/getting-started/intro) server, which allows agents to work server-to-server. The proposed standard [WebMCP](https://shopify.dev/docs/api/web-mcp), meanwhile, is designed for agents that work inside the buyer’s browser. Both leverage Shopify’s [Universal Commerce Protocol](https://www.shopify.com/ucp) (UCP), which provides a common way to search for and discover products, build carts, and check out.\n\nTop AI agents like [Muse](https://www.wsj.com/tech/shopify-to-use-metas-muse-for-agentic-checkout-d23947c0) and [Instinct](https://x.com/noahrshinn/status/2104628465488306183) already have direct partnerships with Shopify for agentic commerce. The Instinct partnership was [announced](https://x.com/noahrshinn/status/2104628465488306183) today.\n\n“If your agent is operating in the buyer’s browser, use WebMCP tools provided on storefront and checkout to efficiently complete order placement, instead of navigating HTML built for humans,” Greenberg wrote on X. “These WebMCP tools provide structured and efficient APIs, purposely designed — via UCP — to ensure accurate commerce facts, required disclosures, and handoff requirements.”", "url": "https://wpnews.pro/news/shopify-opens-checkout-to-browser-based-ai-agents", "canonical_source": "https://techcrunch.com/2026/09/28/shopify-opens-checkout-to-browser-based-ai-agents/", "published_at": "2026-09-28 19:33:57+00:00", "updated_at": "2026-09-28 19:47:40.194117+00:00", "lang": "en", "topics": ["ai-agents", "agent-protocols", "ai-products", "artificial-intelligence"], "entities": ["Shopify", "WebMCP", "Shop Pay", "Gil Greenberg", "Model Context Protocol", "Universal Commerce Protocol", "Muse", "Instinct"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/shopify-opens-checkout-to-browser-based-ai-agents", "markdown": "https://wpnews.pro/news/shopify-opens-checkout-to-browser-based-ai-agents.md", "text": "https://wpnews.pro/news/shopify-opens-checkout-to-browser-based-ai-agents.txt", "jsonld": "https://wpnews.pro/news/shopify-opens-checkout-to-browser-based-ai-agents.jsonld"}}
