AI agents call delete_cli_script to permanently remove resources in Fortimanager — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Although the description is empty and lowers confidence slightly, the tool name explicitly includes 'delete', which falls squarely into the Destructive category. FortiManager manages network security policies and configurations; deleting CLI scripts can remove critical automation or security controls and cannot be easily undone. This warrants high severity due to potential operational impact.
From the tool's definition Tool name is 'delete_cli_script', which indicates irreversible deletion of a CLI script resource. The 'delete' verb is a strong signal of destructive intent.
Documented attack patterns abuse exactly the kind of access delete_cli_script gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Fortimanager, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_cli_script:
{
"version": "1",
"default": "deny",
"hide": [
"delete_cli_script"
]
}delete_cli_script disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

delete_cli_script. It is categorised as a Destructive tool in the Fortimanager MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Fortimanager MCP server in PolicyLayer and add a rule for delete_cli_script: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Fortimanager. Nothing to install.
delete_cli_script is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_cli_script rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_cli_script. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_cli_script is provided by the Fortimanager MCP server (jmpijll/fortimanager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Fortimanager, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
