## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "browser_network_requests",
    "arguments": {}
  }
}
```

## Why browser_network_requests is rated Low

The name implies reading/listing network requests made by the browser, which is a read operation. However, the empty description lowers confidence. Given sibling tools context (browser automation), this likely retrieves network traffic logs without side effects. Severity is medium because network requests can contain sensitive data like credentials or tokens.

From the tool's own definition: "Tool name 'browser_network_requests' suggests retrieval of network request data; description is empty and uninformative."

## Use case

AI agents call browser_network_requests to retrieve information from Playwright without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Playwright:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_network_requests": {}
  }
}
```
