list_firewall_policies
AI agents call list_firewall_policies to retrieve information from FortiManager 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 retrieves firewall policies from FortiManager without creating, modifying, or deleting any configuration. Even though the description is empty, the name clearly indicates a retrieval operation. The blast radius of misuse is minimal—an AI agent listing policies cannot inadvertently damage systems or policies.
