Evaluate Shopify’s documented WebMCP tools through a specific shopping task, using the browser agent and storefront configuration you intend to support.
Start with catalog accuracy and cart behaviour, then verify that agent-assisted actions and the visible storefront agree.

Separate browser tools from a store-owned chatbot
WebMCP lets a shopper’s browser agent call structured tools in the active storefront. Shopify documents these tools on Liquid storefronts and storefronts using its Hydrogen developer preview without a separate installation. This is different from commissioning your own assistant connected to a remote commerce API. Start by understanding which experience you are evaluating.
Check the catalog answers an agent can retrieve
A product still needs clear titles, option values, availability and factual descriptions. Review ambiguous sizes, similar product names and policies that contradict a landing page. An agent cannot reliably resolve a merchandising problem when the underlying catalog and policy content do not explain the difference. Prioritize that information before adding an extra interface.
Observe the customer’s actual cart
The documented tools act in the shopper’s session. Test adding a specific variant, changing a quantity, removing an item and opening the resulting cart. The visible cart and any custom drawer behaviour should agree. Confirm what happens when the requested item is unavailable or the shopper’s request does not identify one option clearly.
Keep ordinary shopping usable
Shopify describes current browser-agent support as limited to Chromium-based browsers. Treat supported-agent testing as an additional journey, not a replacement for forms, links and cart controls. Document the browser and agent used, and keep the full purchase path understandable when no agent is present.
Checks for this implementation
- Review product and policy accuracy before testing agent answers.
- Compare the visible cart with the result after each supported action.
- Retain normal keyboard, touch and account journeys across browsers.
Common mistake to avoid
Treating built-in browser tools as a replacement for accessible shopping controls leaves customers without a supported agent with an incomplete experience.
A strong pilot makes one journey easier while preserving the normal storefront for every visitor and browser.
