AI agents call nodes_delete to permanently remove resources in Remnawave — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes infrastructure (a VPN node) from the system. Node deletion is irreversible and could disrupt service for users relying on that node, making it Destructive rather than merely Write. The high severity reflects the potential operational impact of losing VPN infrastructure.
From the tool's definition Tool name is 'nodes_delete' with description 'Delete a node from Remnawave'. The verb 'Delete' and action of removing a node are irreversible operations that cannot be undone.
Documented attack patterns abuse exactly the kind of access nodes_delete gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Remnawave, and nothing reaches the server without passing your rules. This is the rule we recommend for nodes_delete:
{
"version": "1",
"default": "deny",
"hide": [
"nodes_delete"
]
}nodes_delete 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 Remnawave. It is categorised as a Destructive tool in the Remnawave MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Remnawave MCP server in PolicyLayer and add a rule for nodes_delete: 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 Remnawave. Nothing to install.
nodes_delete 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 nodes_delete 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 nodes_delete. 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.
nodes_delete is provided by the Remnawave MCP server (trackline/mcp-remnawave). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
