create_menu · Shopify Graphql MCP: Risk & Policy

WHAT IT DOES

What create_menu does on Shopify Graphql

AI agents use create_menu to create or update resources in Shopify Graphql — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Shopify Graphql environment.

WHY IT NEEDS A POLICY

Why create_menu needs a policy

This tool creates a new menu resource in Shopify, which is a reversible write operation. It modifies store data but does not execute arbitrary code, trigger financial transactions, or permanently destroy data. The blast radius is medium because incorrect menu creation could impact store navigation and user experience, but changes can be undone by deleting or modifying the menu.

From the tool's definition Tool name 'create_menu' and description 'Create a new navigation menu' indicate data creation. The Shopify GraphQL API context shows this modifies store configuration by adding a new menu resource.
