WHAT IT DOES

What adjust_inventory does on Shopify Graphql

AI agents use adjust_inventory 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.

RISK

Why adjust_inventory is rated Medium

Adjusting inventory quantities modifies stock levels in the Shopify store. This is a Write operation as inventory can be corrected if adjusted incorrectly. However, severity is high because incorrect inventory adjustments can cascade into overselling, stockouts, or financial discrepancies affecting order fulfillment and customer experience.

RECOMMENDED RULE

The rule that runs adjust_inventory safely

adjust_inventory Rate-limited

adjust_inventory 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.
