AI agents call delete_lab to permanently remove resources in EVE-NG MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a lab removes all associated configurations, nodes, networks, and topologies within that lab—an operation that cannot be undone. This qualifies as Destructive rather than Write. The blast radius is high because an AI agent could remove entire lab environments containing significant network configurations, disrupting infrastructure testing and simulations.
From the tool's definition Tool name is 'delete_lab' and description states 'Delete a lab from EVE-NG.' The verb 'delete' combined with the scope of a complete lab indicates irreversible removal of data.
Documented attack patterns abuse exactly the kind of access delete_lab gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and EVE-NG MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_lab:
{
"version": "1",
"default": "deny",
"hide": [
"delete_lab"
]
}delete_lab disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a lab from EVE-NG. It is categorised as a Destructive tool in the EVE-NG MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the EVE-NG MCP Server MCP server in PolicyLayer and add a rule for delete_lab: 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 EVE-NG MCP Server. Nothing to install.
delete_lab 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_lab 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_lab. 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_lab is provided by the EVE-NG MCP Server MCP server (moimran/eveng-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from EVE-NG MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
