AI agents call delete_range to permanently remove resources in Ludus FastMCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data and resources that cannot be undone. It removes not just metadata but entire virtual machines, snapshots, and associated data—a classic destructive operation. The critical severity reflects the blast radius: an AI agent misusing this with confirm=True could destroy an entire cyber range environment and all its contents.
From the tool's definition Tool description explicitly states: 'Delete the entire range. Permanently removes the range and all associated VMs, snapshots, and data.' The word 'Permanently' and the comprehensive scope of deletion (range, VMs, snapshots, all data) confirm irreversible…

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

Delete the entire range. Permanently removes the range and all associated VMs, snapshots, and data. Important: If a deployment is in progress, abort it first with abort_range_deployment(). Args: confirm: Confirmation flag (must be True to proceed) user_id: Optional user ID (admin only) Returns: Range deletion result Example: # Delete current user's range (after aborting if needed) result = await delete_range(confirm=True) Workflow: 1. If deployment is active: abort_range_deployment() 2. Then delete: delete_range(confirm=True). It is categorised as a Destructive tool in the Ludus FastMCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ludus Fast MCP server in PolicyLayer and add a rule for delete_range: 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 Ludus FastMCP. Nothing to install.
delete_range 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_range 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_range. 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_range is provided by the Ludus Fast MCP server (tjnull/ludus-fastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
