AI agents call remove_interface_from_zone 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.
Removing an interface from a zone is a network configuration change that dissociates the interface from its zone, which can disrupt traffic flows and security policies. This is likely irreversible in the sense that the configuration is deleted (the association is removed), placing it in the Destructive category. Confidence is moderate due to the empty description.
From the tool's definition Tool name 'remove_interface_from_zone' implies removal/deletion of a network configuration association; description is empty providing no additional context.
Documented attack patterns abuse exactly the kind of access remove_interface_from_zone 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 remove_interface_from_zone:
{
"version": "1",
"default": "deny",
"hide": [
"remove_interface_from_zone"
]
}remove_interface_from_zone disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

remove_interface_from_zone. 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 remove_interface_from_zone: 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.
remove_interface_from_zone 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 remove_interface_from_zone 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 remove_interface_from_zone. 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.
remove_interface_from_zone 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.
