WHAT IT DOES

What update_subscription_contract_product does on Shopify Graphql

AI agents use update_subscription_contract_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.

RISK

Why update_subscription_contract_product is rated Medium

This tool creates or modifies subscription contract data reversibly. While it affects financial obligations (subscription pricing), the tool itself performs Write operations (modifying contract terms) rather than moving money directly. Misuse could alter customer subscriptions, changing what they receive or their billing rate, making this high-severity.

From the tool's definition Tool description states 'Change a product or product price in a subscription contract' — this modifies existing subscription data (product selection and pricing) which directly affects an active recurring billing arrangement.
