AI agents call list_networks 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 information about existing networks in the CloudStack infrastructure. It performs a read-only query operation, returning network data without creating, modifying, or deleting any resources. While CloudStack is a sensitive infrastructure management system, merely listing networks does not directly enable unauthorized access or expose sensitive credentials—it is informational only.
From the tool's definition Tool name is 'list_networks' and description states 'List networks'. The verb 'list' indicates a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_networks 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_networks:
{
"version": "1",
"default": "deny",
"tools": {
"list_networks": {}
}
}list_networks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List networks. 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_networks: 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_networks 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_networks 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_networks. 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_networks 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.
