WHAT IT DOES

What unifi_list_firewall_groups does on UniFi Access MCP

AI agents call unifi_list_firewall_groups to retrieve information from UniFi Access MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why unifi_list_firewall_groups is rated Low

This tool performs a read-only query operation to enumerate firewall groups (address and port groups) used in firewall policies. Listing configuration objects has no destructive impact, does not execute code or external operations, and does not create or modify data. The blast radius of misuse is minimal—an attacker could enumerate firewall policy structures but cannot alter access controls or execute actions.

From the tool's definition Tool name is 'unifi_list_firewall_groups' and description states 'List firewall groups'. The verb 'list' indicates data retrieval with no side effects.
