WHY IT NEEDS A POLICY

Why tiendanube_update_webhook needs a policy

Updating a webhook modifies system configuration reversibly. While it affects critical integration infrastructure and could be misused to redirect sensitive data to an attacker-controlled endpoint, it is not irreversible (webhooks can be reconfigured again) and does not directly execute code or trigger financial transactions.

From the tool's definition Tool name includes 'update', description explicitly states 'Modify existing webhook configuration including endpoint URL and event type'. Webhooks are configuration entities that control data flow and system integration.
