Lists LUNs on the ONTAP expert mode pool.
AI agents call ontap_lun_list to retrieve information from Google Cloud NetApp Volumes MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only operation to enumerate Logical Unit Numbers (LUNs) on an ONTAP storage pool. It retrieves existing data without creating, modifying, deleting, or executing any external operations. This is a standard inventory/query operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name contains 'list' and description states 'Lists LUNs', which is a query operation that retrieves data without modification or side effects.

Register the Google Cloud NetApp Volumes MCP Server MCP server in PolicyLayer and add a rule for ontap_lun_list: 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.
ontap_lun_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ontap_lun_list 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 ontap_lun_list. 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.
ontap_lun_list 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.
