WHY IT NEEDS A POLICY

Why setup_webhook_alert needs a policy

This tool creates and stores alert rule configuration, which is a reversible write operation. While it modifies local system state (alert rules), it does not execute external operations, delete data irreversibly, or move money. The incomplete description ('When list_payments or get_payment is called,') prevents full assessment of potential side effects, slightly lowering confidence.

From the tool's definition Tool name 'setup_webhook_alert' and description 'Save an alert rule locally' indicates data creation/modification. The tool persists configuration state by saving an alert rule.
