Three new tools — get_checkout, update_checkout, and complete_checkout — let agents inspect and modify order details like address or delivery, then submit the order. The rollout goes to all eligible Shopify merchants, building on Shopify's Universal Commerce Protocol used by both its hosted MCP server and WebMCP. This contrasts with retailers like Amazon and Adidas, which are blocking AI agents from purchasing on their platforms. AI agents Muse and Instinct already have direct agentic-commerce partnerships with Shopify, with the Instinct deal announced the same day. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new WebMCP tools does Shopify provide for AI agent checkout? Shopify's WebMCP checkout support introduces three tools: get_checkout, update_checkout, and complete_checkout.

Shopify's hosted Model Context Protocol server lets agents work server-to-server, while WebMCP is designed for agents operating inside the buyer's browser. Both rely on Shopify's Universal Commerce Protocol, which standardizes product search and discovery, cart building, and checkout across agent types. _Developers choosing between server-side and browser-based agent integrations can track protocol changes like this on daily.dev._ ### Which AI shopping agents already have direct checkout partnerships with Shopify? Muse and Instinct both have direct partnerships with Shopify for agentic commerce, allowing them to complete purchases on Shopify merchant sites.
