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

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

## Why update_cluster_serial_numbers is rated Medium

The tool performs an update operation on cluster serial numbers, which are critical identifiers for network device management. This is reversible (Write rather than Destructive), but represents a high-severity change because incorrect serial number assignments could disrupt device clustering, authentication, or failover mechanisms.

From the tool's own definition: "Tool name 'update_cluster_serial_numbers' indicates modification of cluster configuration identifiers. No description provided, but the verb 'update' and context within FortiManager (network security appliance management) suggest data modification."

## Use case

AI agents use update_cluster_serial_numbers to create or update resources in Fortimanager, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Fortimanager environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "update_cluster_serial_numbers": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
