## Facts

- Tool: `handle_dialog`
- Server: Chrome Devtools (`@async23/chrome-devtools-mcp`) — https://policylayer.com/tools/async23-chrome-devtools-mcp.md
- Install: `npx -y @async23/chrome-devtools-mcp`
- Homepage: https://github.com/Async23/chrome-devtools-mcp
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why handle_dialog is rated High

This tool triggers an external browser action (accepting or dismissing a dialog) whose effect depends on arguments. It is not purely read-only and can influence browser state and page flow, making it Execute. Misuse could cause unintended form submissions or confirmation of destructive browser dialogs, but blast radius is limited to the current page session.

From the tool's own definition: "handle_dialog - 'If a browser dialog was opened, use this command to handle it'"

## Use case

AI agents invoke handle_dialog to trigger actions in Chrome Devtools. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "handle_dialog": {
      "limits": [
        {
          "counter": "handle_dialog_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
