Shopify Storefront API
Shopify's GraphQL API for building custom and headless storefronts, and the same interface AI agents and MCP integrations use to query a store programmatically.
What it means
The Storefront API exposes a store's catalog, cart, and checkout functionality as queryable data rather than rendered HTML. It's the foundation Shopify Hydrogen and headless storefronts are built on, and it's also the practical bridge between a Shopify store and AI agent frameworks, an MCP server or agent integration typically reads catalog data through this API rather than parsing storefront pages.
Why it matters for Shopify
Shopify merchants with a well-structured Storefront API integration make their catalog directly queryable by AI agents and MCP servers, instead of relying on those systems to scrape rendered pages.
