WHAT IT DOES

What create_service_icmp does on FortiManager MCP Server

AI agents use create_service_icmp 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 create_service_icmp is rated Medium

This tool creates a new service definition for ICMP traffic, which modifies the firewall configuration state reversibly. It is a Write operation (creates/adds a configuration object) rather than Read (no query), Execute (doesn't run arbitrary code), Destructive (reversible), or Financial.

From the tool's definition Tool name 'create_service_icmp' indicates creation of a service object for ICMP protocol within FortiManager's centralized firewall policy management system.

RECOMMENDED RULE

The rule that runs create_service_icmp safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FortiManager MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_service_icmp, this is the rule to start with:

create_service_icmp Rate-limited

create_service_icmp stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
