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

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

## Why take_screenshot is rated Low

Taking a screenshot is a read-only operation that queries the current state of a rendered page or DOM element. It retrieves visual information without creating, modifying, deleting, or executing arbitrary code. While screenshots could theoretically capture sensitive information (e.g., displayed credentials), the tool itself performs no destructive, financial, or code-execution actions.

From the tool's own definition: "Tool name 'take_screenshot' and description 'Take a screenshot of the page or element' indicate a retrieval operation that captures visual state without modifying any data or triggering side effects."

## Use case

AI agents call take_screenshot to retrieve information from Chrome DevTools 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 Chrome DevTools MCP:

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