AI agents call system_interface_delete to permanently remove resources in FortiOS 7 6 X MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting system interfaces is an irreversible action that can completely disconnect a FortiOS firewall from the network, severing all communication and rendering the device operationally unavailable. This is a destructive action with maximum blast radius on a critical infrastructure device. Despite the empty description, the tool name unambiguously indicates a destructive operation on a critical system resource.
From the tool's definition Tool name 'system_interface_delete' explicitly indicates deletion of system network interfaces. The 'delete' verb combined with 'system_interface' (critical infrastructure component) indicates irreversible removal of network configuration.

Documented attack patterns abuse exactly the kind of access system_interface_delete gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FortiOS 7 6 X MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for system_interface_delete:
{
"version": "1",
"default": "deny",
"hide": [
"system_interface_delete"
]
}system_interface_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

system_interface_delete. It is categorised as a Destructive tool in the FortiOS 7 6 X MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the FortiOS 7 6 X MCP Server MCP server in PolicyLayer and add a rule for system_interface_delete: 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 FortiOS 7 6 X MCP Server. Nothing to install.
system_interface_delete 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 system_interface_delete 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 system_interface_delete. 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.
system_interface_delete is provided by the FortiOS 7 6 X MCP Server MCP server (paoloamato2/fortinet-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FortiOS 7 6 X MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
