AI agents call delete_node 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.
This tool permanently removes a node from a lab topology. While the blast radius is contained to the lab environment (not affecting live production systems), deletion of nodes cannot be undone and represents a destructive action that irreversibly alters the lab configuration.
From the tool's definition Tool name is 'delete_node' and description states 'Delete a node from a lab.' The verb 'delete' indicates irreversible removal of an entity.
Documented attack patterns abuse exactly the kind of access delete_node 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_node:
{
"version": "1",
"default": "deny",
"hide": [
"delete_node"
]
}delete_node 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 node from a lab. 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_node: 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_node 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_node 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_node. 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_node 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.
