Cancels a long-running operation that is still in progress
AI agents call gcnv_operation_cancel 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.
Cancelling an in-progress operation is irreversible — the cancelled operation cannot be resumed. Depending on what operation was running (e.g., volume creation, backup, replication), cancellation can leave resources in a partially created or corrupted state, cause data loss, or interrupt critical workflows. This irreversibility and potential blast radius place it in the Destructive category.

Attacks that exploit this kind of access
Cancels a long-running operation that is still in progress. 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_operation_cancel: 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_operation_cancel 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_operation_cancel 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_operation_cancel. 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_operation_cancel 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.
