List VIP/public NAT exposure and firewall policies that reference VIP objects.
AI agents call fortigate_get_public_exposure to retrieve information from Fortigate MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing firewall configuration data (VIP/NAT exposure and policy references) without modifying, executing, or deleting anything. It is purely informational for security analysis purposes. The blast radius of misuse is minimal since it only exposes what configuration already exists on the firewall, which is typical security reconnaissance activity within a read-only diagnostic context.
From the tool's definition Tool description states 'List VIP/public NAT exposure and firewall policies' - uses 'List' verb indicating data retrieval. Server description emphasizes 'read-only querying and diagnostics' with no modification, deletion, or execution capabilities.
