THE RISK

Low Risk

Why browser_hover needs a policy

The description is empty, providing no information about what this tool does. The name 'browser_hover' suggests a UI browser interaction (hovering over an element), which would normally be classified as Execute. However, the extremely low confidence is due to the empty description and the apparent mismatch with the SNS/SQS server context.

From the tool's definition Tool name is 'browser_hover' with an empty description. This appears to be a browser interaction tool (hover action) that seems out of place on an Amazon SNS/SQS MCP server.

POLICY

How to control browser_hover

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_hover:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_hover": {
      "limits": [
        {
          "counter": "browser_hover_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

browser_hover gets a rate cap, and everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
