What firewall_set_panel_port does on Aapanel
AI agents use firewall_set_panel_port to create or update resources in Aapanel, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aapanel environment.
Why firewall_set_panel_port is rated Medium
This tool changes the aaPanel access port, which is a configuration modification that affects how the system is accessed. It is Write (creates or modifies data reversibly) rather than Execute because it updates a stored setting rather than triggering an arbitrary external operation.
From the tool's definition 'Change the aaPanel access port' – modifies a configuration setting that controls network access to the panel, a reversible but critical infrastructure change.
