## Why list_pages is rated Low

This tool retrieves information about currently open browser pages without modifying, executing, or deleting anything. It is a passive inspection capability that fits the Read category. Severity is low because listing pages exposes only metadata about open tabs/windows, not sensitive page content, and the blast radius of accidental misuse is minimal.

From the tool's own definition: "Tool name 'list_pages' and description 'Get a list of pages open in the browser' indicate a query/retrieval operation with no side effects."

## Use case

AI agents call list_pages to retrieve information from Chrome DevTools MCP 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 Chrome DevTools MCP:

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