## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,

## Why create_ipv4_subnet_for_guest_network is rated Medium

This tool creates a new network resource (IPv4 subnet) which modifies infrastructure state reversibly. It is a Write operation as it creates data that can be updated or deleted later. Severity is medium because misconfiguration of network subnets could cause connectivity issues or isolation problems in the guest network, but the effect is recoverable through subnet deletion or modification.

From the tool's own definition: "Tool name indicates 'create' operation; description states 'Create IPv4 subnet for guest network', which creates new network configuration resources."

## Use case

AI agents use create_ipv4_subnet_for_guest_network 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.

## Recommended policy (PolicyLayer)
