create_product · Shopify Graphql MCP: Risk & Policy

WHAT IT DOES

What create_product does on Shopify Graphql

AI agents use create_product 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_product needs a policy

This tool creates new product data in the Shopify store, which is a write operation. While it modifies store state, the action is reversible (products can be deleted or modified). It does not execute arbitrary code, delete data irreversibly, or move money. The severity is medium because creating unwanted products could clutter the store and require manual cleanup, but the impact is bounded and recoverable.

From the tool's definition Tool name 'create_product' and description 'Create a new product in the Shopify store' indicate creation of new data in a reversible manner.

create_product Rate-limited

create_product 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.
