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

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

  "method": "tools/call",
  "params": {
    "name": "change_device_serial_number",
    "arguments": {}

```

## Why change_device_serial_number is rated Medium

The name implies modifying a device's serial number, which is a Write operation that could affect device identity and management integrity. However, with no description, confidence is low. Serial number changes in FortiManager could have significant impact on device tracking and licensing, warranting a high severity.

From the tool's own definition: "Tool name: 'change_device_serial_number' — no description provided."

## Use case

AI agents use change_device_serial_number 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
