AI agents call list_storage_pools to retrieve information from CloudStack MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates existing storage pool data with no side effects. It performs a simple informational lookup without creating, modifying, deleting, or executing operations. The low severity reflects minimal risk even if called repeatedly or with broad parameters, as it only exposes configuration/inventory metadata.
From the tool's definition Tool name 'list_storage_pools' and description 'List storage pools' indicate a read-only query operation that retrieves information about storage pool resources without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access list_storage_pools gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CloudStack MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_storage_pools:
{
"version": "1",
"default": "deny",
"tools": {
"list_storage_pools": {}
}
}list_storage_pools is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List storage pools. It is categorised as a Read tool in the CloudStack MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for list_storage_pools: 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 CloudStack MCP Server. Nothing to install.
list_storage_pools 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 list_storage_pools 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 list_storage_pools. 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.
list_storage_pools is provided by the CloudStack MCP Server MCP server (phantosmax/cloudstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CloudStack MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
