## Why asc_patch_marketplace_webhook is rated Medium

This tool modifies webhook configuration (endpoint URL and secret rotation) which are reversible changes without permanent data loss. However, severity is high because misconfiguring webhook endpoints could disrupt critical App Store Connect integrations (e.g., subscription updates, review notifications), and an incorrect secret rotation could break authentication flows.

From the tool's own definition: "Tool description explicitly states 'update endpointUrl and/or rotate the secret' which are reversible configuration modifications to a webhook endpoint."
