AI agents call firewalla_list_rules to retrieve information from Firewalla without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays existing firewall rules for audit purposes. It has no capability to create, modify, delete, or execute any actions—it only queries and returns rule configuration data. This is a classic Read operation with minimal risk.
