WHAT IT DOES

What ontap_lun_create does on Google Cloud NetApp Volumes MCP Server

AI agents use ontap_lun_create to create or update resources in Google Cloud NetApp Volumes MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Cloud NetApp Volumes MCP Server environment.

WHY IT NEEDS A POLICY

Why ontap_lun_create needs a policy

This tool creates a new logical unit number (LUN) on an ONTAP volume, which is a reversible write operation that provisions storage. The action modifies cloud infrastructure by adding a new storage entity. While reversible (via deletion), the impact is significant as it allocates cloud resources, affects storage configuration, and could disrupt existing ONTAP volume operations if misconfigured.

From the tool's definition Tool name 'ontap_lun_create' and description 'Creates a LUN (Logical Unit Number) on an ONTAP volume' explicitly indicate creation of a new storage resource.
