Why browser_handle_dialog needs a policy

The tool name implies browser dialog handling, which is a browser action/execution category. However, the description is empty, so confidence is low. Browser automation tools can have significant side effects depending on what dialogs they handle.

From the tool's definition Tool name 'browser_handle_dialog' suggests browser automation/interaction; description is empty and uninformative.

POLICY

How to control browser_handle_dialog

PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Amazon Sns Sqs, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_handle_dialog:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_handle_dialog": {
      "limits": [
        {
          "counter": "browser_handle_dialog_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

browser_handle_dialog stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Awslabs Amazon Sns Sqs — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
