Lists GCNV managed volumes in the specified storage pool (omit location for all locations).
AI agents call gcnv_volume_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.
This tool performs a query/list operation to retrieve information about existing volumes. It has no side effects—no data is created, modified, deleted, or executed. The optional location parameter is a filter for the query, not an action parameter. This is a straightforward Read category operation with low severity since it only accesses informational metadata about cloud storage resources.
From the tool's definition Tool name 'gcnv_volume_list' and description 'Lists GCNV managed volumes' indicate a read-only retrieval operation that queries existing volumes without modifying or deleting them.
Attacks that exploit this kind of access
Lists GCNV managed volumes in the specified storage pool (omit location for all locations). It is categorised as a Read tool in the Google Cloud NetApp Volumes MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Google Cloud NetApp Volumes MCP Server MCP server in PolicyLayer and add a rule for gcnv_volume_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.
gcnv_volume_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 gcnv_volume_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 gcnv_volume_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.
gcnv_volume_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.
