Deletes a host group in the specified project and location
AI agents call gcnv_host_group_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.
Deletion of cloud infrastructure resources like host groups is an irreversible operation that cannot be undone. While not directly financial, the loss of a host group could disrupt services and data access, making it a destructive action with high blast radius if triggered by an AI agent without proper authorization or context. Destructive is the most severe applicable category here.
From the tool's definition Tool name explicitly contains 'delete' and description states 'Deletes a host group'; this operation removes a resource irreversibly with no undo mechanism.

Deletes a host group in the specified project and location. It is categorised as a Destructive tool in the Google Cloud NetApp Volumes MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Google Cloud NetApp Volumes MCP Server MCP server in PolicyLayer and add a rule for gcnv_host_group_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.
gcnv_host_group_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 gcnv_host_group_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 gcnv_host_group_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.
gcnv_host_group_delete is provided by the Google Cloud NetApp Volumes MCP Server MCP server (netapp/gcnv-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
