AI agents may call empty_queue to permanently remove or destroy resources in SimplyPrint: 3D Print Farm Management. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call empty_queue in a loop, permanently destroying resources in SimplyPrint: 3D Print Farm Management. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access empty_queue gives an agent. Each links to the full case and the policy that stops it:
Other destructive tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
DESTRUCTIVE: Delete all items from the queue (optionally filtered by group or done-only). Confirm with the user before calling.. It is categorised as a Destructive tool in the SimplyPrint: 3D Print Farm Management MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the SimplyPrint: 3D Print Farm Management MCP server in PolicyLayer and add a rule for empty_queue: 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 SimplyPrint: 3D Print Farm Management. Nothing to install.
empty_queue 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 empty_queue 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 empty_queue. 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.
empty_queue is provided by the SimplyPrint: 3D Print Farm Management MCP server (https://simplyprint.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
