WHAT IT DOES

What update_address_group does on FortiManager MCP Server

WHY IT NEEDS A POLICY

Why update_address_group needs a policy

The tool updates firewall address group objects, which is a reversible modification of network security configurations. This is a Write operation rather than Execute because it modifies policy data directly rather than triggering code execution. Severity is high because misconfigured address groups can affect network security posture and traffic filtering rules across managed devices.

From the tool's definition Tool name 'update_address_group' and server context (FortiManager for firewall policy management and network configuration) indicate modification of address group configurations.
