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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "assign_to_load_balancer_rule",
    "arguments": {}
  }
}
```

## Why assign_to_load_balancer_rule is rated Medium

Assigning VMs to load balancer rules modifies the active traffic routing configuration and network load distribution. This is reversible (VMs can be removed from rules), so it is Write rather than Destructive. However, the blast radius is high because incorrect assignments could disrupt network traffic, impact service availability, and affect multiple customer-facing systems.

From the tool's own definition: "Assigns virtual machines to load balancer rule: the tool 'assign_to_load_balancer_rule' creates or modifies network load balancing configuration by associating VM instances with a load balancer rule. This is a write operation that changes infrastructure state."

## Use case

AI agents use assign_to_load_balancer_rule 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)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches CloudStack MCP Server:
