install_package · FortiManager MCP Server MCP: Risk & Policy

WHAT IT DOES

What install_package does on FortiManager MCP Server

AI agents invoke install_package to trigger actions in FortiManager MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why install_package needs a policy

Installing a package on FortiManager typically means pushing/deploying firewall policy packages to managed devices, which triggers external operations that reconfigure live network security infrastructure. This is an Execute-level action with critical severity since misconfiguration could expose or block network traffic across all managed firewalls.

From the tool's definition Tool name 'install_package' on a FortiManager server that handles 'centralized firewall policy management, device provisioning, and network configuration'
