Remove unschedulable from a node (uncordon).
AI agents call uncordon_node to permanently remove resources in K8s MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call uncordon_node doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from K8s MCP is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
Remove unschedulable from a node (uncordon). It is categorised as a Destructive tool in the K8s MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the K8s MCP server in PolicyLayer and add a rule for uncordon_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 K8s MCP. Nothing to install.
uncordon_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 uncordon_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 uncordon_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.
uncordon_node is provided by the K8s MCP server (rahul007-bit/k8s-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
