run_shopifyql_query · Shopify Graphql MCP: Risk & Policy

WHAT IT DOES

What run_shopifyql_query does on Shopify Graphql

AI agents invoke run_shopifyql_query to trigger actions in Shopify Graphql. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why run_shopifyql_query needs a policy

This tool falls under Execute rather than Read because it actively runs/executes queries whose effects and data access scope depend entirely on the query arguments provided by the AI agent. While it may appear read-only (analytics/reporting), ShopifyQL execution can access and retrieve sensitive business data at scale, and in some contexts query execution itself can have side effects or resource implications.

From the tool's definition Tool description states 'Execute a ShopifyQL query' — the verb 'Execute' combined with the capability to run arbitrary ShopifyQL queries indicates this tool runs user-supplied code/queries against the Shopify backend.
