## Why unifi_update_firewall_group is rated Medium

This tool modifies firewall rules, which are critical security controls. While reversible (can be updated again), misuse could disrupt network security policies or allow unauthorized network access. It falls under Write (modifiable) rather than Execute (code execution) or Destructive (irreversible deletion).

From the tool's own definition: "Tool name 'unifi_update_firewall_group' and description 'Update an existing firewall group' indicate modification of network security configuration. The requirement for 'the full group object' suggests structured data mutation rather than deletion."
