Shopify opens checkout to browser-based AI agents, contrasting with Amazon and Adidas

Shopify announced Monday that it has added WebMCP support for checkout, including Shop Pay, allowing AI agents to read the checkout screen, update it, and submit the transaction with the buyer's authorization. Previously, Shopify supported WebMCP only for storefronts and carts, enabling agents to browse inventory and add items to a cart. The company said the new feature means agents no longer need to rely on screenshots or scraping webpages to complete a purchase.

The update introduces three new tools: get_checkout, update_checkout, and complete_checkout. These allow an agent to inspect a checkout, modify details such as the customer's address or delivery option, and then place an order after the buyer authorizes it.

Gil Greenberg, a staff product manager focused on agentic commerce at Shopify, said in a post on X that the feature is rolling out to all eligible merchants.

The announcement positions Shopify as an early enabler of AI-driven commerce, while other major retailers take a more cautious approach. Last week, Bloomberg reported that Amazon was blocking Meta's Muse AI agent from its retail site. Adidas has also reportedly blocked AI agents from making purchases.

Shopify's move suggests the company sees AI agents as a growing channel for commerce, betting that browser-based agents will become a standard way for consumers to shop, particularly for routine purchases. The requirement for buyer authorization at checkout provides a layer of security and consent that may address concerns about automated transactions.

Analysis

Why This Matters

Shopify's decision to allow AI agents to complete purchases could accelerate adoption of agentic commerce, where AI handles routine shopping tasks on behalf of users.
The contrast with Amazon and Adidas highlights a split in retail strategy: some companies see AI agents as a threat to direct customer engagement, while others view them as a new sales channel.
For consumers, this could mean more seamless, automated purchasing experiences, but it also raises questions about fraud, returns, and control over transactions.

Background

Browser-based AI agents have been evolving rapidly, with companies like OpenAI, Google, and Anthropic developing tools that can navigate websites and perform tasks. The Model Context Protocol (MCP), which includes WebMCP, is a standard for allowing these agents to interact with web services in a structured way, moving beyond simple scraping. Shopify's adoption of WebMCP for checkout represents a significant integration of AI agents into the actual purchasing flow, not just product discovery.

Key Perspectives

Shopify: By embracing AI agents, Shopify positions itself as a forward-thinking platform that supports emerging technologies. The company likely sees this as a way to increase transaction volume and merchant sales, especially for repeat and routine purchases. Amazon and Adidas: These retailers are blocking AI agents, possibly to protect against automated bot activity, preserve direct customer relationships, or prevent misuse such as scalping or fraudulent transactions. Their stance suggests concern over loss of control over the shopping experience. Critics and security experts: The new tools require buyer authorization, which mitigates some risks, but the broader security implications of agentic commerce are still being understood. Critics may worry about phishing, unauthorized use of agents, or the potential for AI agents to make mistakes or be manipulated.

What to Watch

Adoption rate of the new checkout tools by Shopify merchants, especially larger stores.
Any security incidents or fraud patterns that emerge as AI agents begin completing transactions at scale.
Reactions from other major retailers: will more follow Shopify's lead or Amazon's blockade?
Potential regulatory attention on agentic commerce, particularly around consumer protections and data privacy.
