WHAT IT DOES

What protect_alarm_update_rule does on UniFi Access MCP

RISK

Why protect_alarm_update_rule is rated Medium

The tool modifies alarm rules in a UniFi Access system managing doors and physical security. While reversible (Write, not Destructive), misconfiguration could disable critical security alarms, creating high blast radius. Confidence is lowered from higher due to empty description, but the semantic meaning of 'update_rule' is clear.

From the tool's definition Tool name 'protect_alarm_update_rule' indicates modification of alarm rules. Description is empty but the verb 'update' combined with 'rule' on a physical access control system suggests reversible modification of security policies.
