List all ACL (firewall) rules at a site
AI agents call unifi_list_acl_rules to retrieve information from UniFi Network MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing firewall rule configurations without modifying, deleting, or executing any changes to the network infrastructure. It is purely informational and poses minimal risk even if misused by an AI agent, as it only exposes data about current security policies rather than allowing modification of them.
From the tool's definition Tool name contains 'list' and description states 'List all ACL (firewall) rules' - a retrieval operation with no side effects.
