Why browser_network_requests needs a policy

With an empty description, classification is speculative. The name suggests it may capture or read browser network traffic (a Read operation), but it could also execute browser actions. Confidence is low due to lack of description. Defaulting to Other given the uncertainty, though Read or Execute are plausible.

From the tool's definition Tool description is empty and uninformative. The tool name 'browser_network_requests' suggests reading/monitoring network requests in a browser context, but no description is provided.

POLICY

How to control browser_network_requests

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS HealthOmics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_network_requests:

policy.json

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

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

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