## Why asc_patch_subscription_localization is rated Medium

This tool modifies subscription localization data (name and description fields) which are reversible changes. While subscriptions involve financial products, the tool itself only updates presentation metadata, not payment terms or financial commitments. The blast radius is limited to subscription text fields rather than financial transactions or irreversible deletions.

From the tool's own definition: "Tool description states 'Update name and/or description on an existing SubscriptionLocalization' - the verb 'Update' combined with modifying subscription metadata indicates a write operation that creates or modifies data reversibly."

## Use case

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