# Screenshot

Captures a fast screenshot-first desktop snapshot with cursor position, desktop/window summaries, and an image. This path skips UI tree extraction for speed. Use Snapshot when you need interactive element ids, scrollable regions, or browser DOM extraction. Note: the returned image may be downscaled for efficiency; when it is, multiply image coordinates by the ratio of original size to displayed size to get the actual screen coordinates for mouse actions (Click, Move, etc.).

## Facts

- Tool: `Screenshot`
- Server: Windows-MCP (`13888285815/windows-mcp`) — https://policylayer.com/tools/13888285815-windows-mcp.md
- Homepage: https://github.com/13888285815/windows-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why Screenshot is rated Low

Screenshot captures visual information from the screen without modifying, deleting, or executing any code. It is a read-only operation that retrieves display data. The only minor caveat is that cursor position is included, but this is still passive observation rather than active manipulation.

From the tool's own definition: "Tool 'captures' and 'returns' a screenshot; operations are 'desktop snapshot', 'image', read-only with no modification of system state."

## Use case

AI agents call Screenshot to retrieve information from Windows-MCP 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 Windows-MCP:

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