THE RISK

Low Risk

Why browser_hover needs a policy

The description is empty and uninformative, lowering confidence significantly. The tool name 'browser_hover' suggests a browser UI interaction (Execute category), but it is anomalously placed on an Amazon Translate server. Without a description, and given the contextual mismatch, confidence is very low.

From the tool's definition Tool name is 'browser_hover' but description is empty. The name suggests a browser interaction (hovering over an element), which would normally be Execute, but this tool appears completely out of context for an Amazon Translate MCP server.

POLICY

How to control browser_hover

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Translate MCP Server, 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.
