pt_remove_nat
AI agents call pt_remove_nat to permanently remove resources in MCP Packet Tracer — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The 'remove' prefix strongly implies deletion or irreversible removal of NAT configuration from network devices. NAT removal can disrupt network connectivity for all devices relying on that translation, making this potentially high-impact.
From the tool's definition Tool name 'pt_remove_nat' suggests removal/deletion of NAT (Network Address Translation) configuration; sibling tools include destructive operations like 'pt_delete_device' and 'pt_delete_link'
Attacks that exploit this kind of access
pt_remove_nat. It is categorised as a Destructive tool in the MCP Packet Tracer MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Packet Tracer MCP server in PolicyLayer and add a rule for pt_remove_nat: 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 MCP Packet Tracer. Nothing to install.
pt_remove_nat 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 pt_remove_nat 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 pt_remove_nat. 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.
pt_remove_nat is provided by the MCP Packet Tracer MCP server (mainorcruz/mcp_packet_tracer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
