AI agents use enable_static_nat to create or update resources in CloudStack MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CloudStack MCP Server environment.
Static NAT configuration is a network-level write operation that establishes inbound routing rules to VMs. While reversible (can be disabled), misuse could expose private infrastructure to the public internet or redirect traffic in unintended ways, creating significant security and operational risk.
From the tool's definition Tool name 'enable_static_nat' and description 'Enable static NAT for an IP to a VM' indicate a network configuration modification.
Documented attack patterns abuse exactly the kind of access enable_static_nat 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 enable_static_nat:
{
"version": "1",
"default": "deny",
"tools": {
"enable_static_nat": {
"limits": [
{
"counter": "enable_static_nat_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}enable_static_nat stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Enable static NAT for an IP to a VM. It is categorised as a Write tool in the CloudStack MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for enable_static_nat: 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.
enable_static_nat is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the enable_static_nat 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 enable_static_nat. 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.
enable_static_nat 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.
