AI agents call pt_remove_acl_object to permanently remove resources in Packet Tracer MCP — 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 of an ACL (Access Control List) object, which is likely irreversible within the network topology configuration. Sibling tools like 'pt_delete_device' and 'pt_delete_link' confirm this server uses destructive operations. Removing an ACL object could have significant network security implications.
From the tool's definition Tool name 'pt_remove_acl_object' suggests removal/deletion of an ACL object; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access pt_remove_acl_object gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Packet Tracer MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for pt_remove_acl_object:
{
"version": "1",
"default": "deny",
"hide": [
"pt_remove_acl_object"
]
}pt_remove_acl_object disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

pt_remove_acl_object. It is categorised as a Destructive tool in the Packet Tracer MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Packet Tracer MCP server in PolicyLayer and add a rule for pt_remove_acl_object: 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 Packet Tracer MCP. Nothing to install.
pt_remove_acl_object 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_acl_object 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_acl_object. 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_acl_object is provided by the Packet Tracer MCP server (mats2208/mcp-packet-tracer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Packet Tracer MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
