cluster_auto_upgrade_delete
AI agents call cluster_auto_upgrade_delete to permanently remove resources in GreenNode MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool deletes (rather than disables or modifies) cluster auto-upgrade settings, which is an irreversible destructive action on cloud infrastructure. Even though the description is empty, the name unambiguously indicates a deletion operation on Kubernetes cluster configuration.
From the tool's definition Tool name 'cluster_auto_upgrade_delete' indicates deletion of auto-upgrade configuration. Server context shows management of Kubernetes clusters in VNG Cloud infrastructure.
Attacks that exploit this kind of access
cluster_auto_upgrade_delete. It is categorised as a Destructive tool in the GreenNode MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the GreenNode MCP Server MCP server in PolicyLayer and add a rule for cluster_auto_upgrade_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 GreenNode MCP Server. Nothing to install.
cluster_auto_upgrade_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 cluster_auto_upgrade_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 cluster_auto_upgrade_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.
cluster_auto_upgrade_delete is provided by the GreenNode MCP Server MCP server (vngcloud/greennode-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
