Adobe Commerce Added an MCP Layer: Your Catalog Is Now an Agent's Tool
On Thursday, April 9, 2026, an AI shopping agent could call search_shop_catalog on any Shopify store's Storefront MCP endpoint and get products back. On Friday morning, April 10, the same call returned Tool not found: search_shop_catalog. Shopify had moved its catalog tools to the Universal Commerce Protocol shape, renamed the tool to search_catalog, and wrapped its arguments in a new nested catalog object. Developers found out when their agents stopped working and started asking about it on the community forum.
