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 create_menu is rated Medium
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.
Attacks that exploit this kind of access
The rule that runs create_menu safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Shopify Graphql, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_menu, this is the rule to start with:
create_menu stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Shopify Graphql, apply this rule, and every create_menu call is checked against it from then on.
