Delete a PostgreSQL cluster.
AI agents call delete_postgres_cluster to permanently remove resources in CloudNativePG MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of a database cluster is a destructive, irreversible operation with maximum blast radius. It exceeds Execute severity because the action cannot be undone and results in complete data loss. This is classified as Destructive per the highest-severity rule, warranting critical severity due to the potential loss of all data in the cluster and operational disruption.
From the tool's definition Tool name is 'delete_postgres_cluster' and description states 'Delete a PostgreSQL cluster.' This operation irreversibly removes an entire PostgreSQL cluster, destroying all associated data and infrastructure.
Attacks that exploit this kind of access
Delete a PostgreSQL cluster. It is categorised as a Destructive tool in the CloudNativePG MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the CloudNativePG MCP Server MCP server in PolicyLayer and add a rule for delete_postgres_cluster: 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 CloudNativePG MCP Server. Nothing to install.
delete_postgres_cluster 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_postgres_cluster 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_postgres_cluster. 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_postgres_cluster is provided by the CloudNativePG MCP Server MCP server (wateim/cnpg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
