THE RISK

Why browser_click needs a policy

Browser click actions execute UI interactions that can trigger a wide range of side effects depending on what is clicked. The name strongly implies browser automation. Empty description lowers confidence, but the potential blast radius of arbitrary browser clicks is high. Classified as Execute since clicks can trigger operations whose effects depend on arguments/context.

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

Documented attack patterns abuse exactly the kind of access browser_click gives an agent:

POLICY

How to control browser_click

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_click:

policy.json

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

browser_click 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.
