Remove a VPS from the registry
AI agents call vps_unregister to permanently remove resources in ML Lab MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Unregistering a VPS from the registry is an irreversible deletion of that registry entry. Once removed, the VPS configuration, credentials references, and metadata stored in the registry are lost. This cannot be undone without re-adding the VPS manually, making it Destructive in nature.
From the tool's definition 'Remove a VPS from the registry' — permanently removes/unregisters a VPS entry
Attacks that exploit this kind of access
Remove a VPS from the registry. It is categorised as a Destructive tool in the ML Lab MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the ML Lab MCP server in PolicyLayer and add a rule for vps_unregister: 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 ML Lab MCP. Nothing to install.
vps_unregister 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 vps_unregister 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 vps_unregister. 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.
vps_unregister is provided by the ML Lab MCP server (pushpullcommitpush/ml-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
