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

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

## Why capture_screenshot is rated Low

Screenshot capture is fundamentally a read operation — it queries and retrieves visual information from the desktop without modifying, executing, or destroying anything. While there are privacy concerns with screenshot capabilities, the action itself is read-only retrieval.

From the tool's own definition: "Tool name is 'capture_screenshot' which performs image capture of the desktop. The sibling tools include read-only monitoring functions like 'get_battery_status', 'get_cpu_per_core', 'get_display_info', and 'get_network_stats'."

## Use case

AI agents call capture_screenshot to retrieve information from Desktop Commander MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Desktop Commander MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "capture_screenshot": {}
  }
}
```
