Add shopping and Shop Pay checkout to any agent with Shop MCP

It works with over 1 billion products in Shopify Catalog and doesn't require an API key for search. Nothing changes for existing Catalog API integrations, and no action is required.
Detect when a POS extension screen finishes navigating
What changed The POS Navigation API adds the navigatesuccess event. It fires after the destination screen finishes its native transition, and its callback receives a standard Event. currententrychange can fire before the screen finishes appearing, and the navigate() promise doesn’t wait for the transition.
Identify the published version running in a POS extension
What changed shopify.extension.version returns the version of the extension that is running. It’s the same name shown on the Versions page in the Dev Dashboard and chosen when running shopify app deploy. The value is an opaque name, not a version number, so compare it for equality rather than sorting it.
Cart updates that result in no changes to the cart no longer trigger carts/update webhooks
Cart operations that leave the cart unchanged, for example, resubmitting the same values a cart already has, no longer trigger a carts/update webhook. Shopify sends a webhook every time a cart's contents or properties change. Previously, every cart operation produced a carts/update webhook.

The price field doesn’t change. No action is required. list_price is an optional field defined in the UCP catalog specification, version 2026-08-25 .
