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

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

## Why Notification is rated Medium

This tool creates transient notification objects that do not persist or modify underlying data, configuration, or system state. While it is an output action (not purely observational like Read), it is reversible and non-destructive—the notification can be dismissed and leaves no lasting impact. It does not execute code, delete data, or move money.

From the tool's own definition: "The tool 'Sends a Windows toast notification with a title and message.' creates a temporary UI element (notification) that is displayed to the user without modifying system data or configuration."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "Notification": {
      "limits": [
        {
          "counter": "notification_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
