WHAT IT DOES

What update_firewall_policy does on FortiManager MCP Server

AI agents use update_firewall_policy to create or update resources in FortiManager MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FortiManager MCP Server environment.

RISK

Why update_firewall_policy is rated Medium

This tool creates or modifies firewall policies reversibly—a Write operation. Severity is high because misconfiguration of firewall policies can expose networks to unauthorized traffic, compromise security posture, or disrupt legitimate connectivity. Confidence is 0.85 (not higher) because the tool description is empty and we rely on name semantics and server context; a full description would strengthen certainty.

From the tool's definition Tool name 'update_firewall_policy' indicates modification of firewall policy configuration. Server context shows this is a FortiManager JSON-RPC API for 'centralized firewall policy management'.
