Deletes a backup from the specified backup vault
AI agents call gcnv_backup_delete to permanently remove resources in Google Cloud NetApp Volumes MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Backup deletion is a destructive operation that cannot be undone. Once deleted, the backup is permanently removed, eliminating a recovery point for data restoration. This has high blast radius if an AI agent incorrectly identifies or targets the wrong backup for deletion, potentially compromising disaster recovery capabilities.
From the tool's definition Tool name contains 'delete' and description states 'Deletes a backup from the specified backup vault' — this operation irreversibly removes a backup resource that cannot be recovered through the tool itself.

Register the Google Cloud NetApp Volumes MCP Server MCP server in PolicyLayer and add a rule for gcnv_backup_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 Google Cloud NetApp Volumes MCP Server. Nothing to install.
