Why browser_navigate_back needs a policy

The description is empty and uninformative, making classification uncertain. The tool name suggests browser navigation (going back), which would typically be Execute category. However, given the mismatch with the SNS/SQS server context and lack of any description, confidence is very low. Classifying as Other due to insufficient information and apparent context mismatch.

From the tool's definition Tool name is 'browser_navigate_back' with empty description. The name suggests a browser navigation action (going back in browser history), which is an Execute-type action, but it seems out of place on an Amazon SNS/SQS MCP server.

How to control browser_navigate_back

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_navigate_back:

policy.json

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

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