## Why get_console_warn is rated Low

This tool retrieves console warning messages from the browser, which is a read-only operation with no side effects. It queries existing data without creating, modifying, executing, or deleting anything. The low severity reflects minimal risk even if misused by an agent—it only exposes developer-level diagnostic information that may already be visible in browser DevTools.

From the tool's own definition: "Tool name 'get_console_warn' and description 'Get console warning messages' indicate retrieval of existing log data with no modification or execution."

## Use case

AI agents call get_console_warn to retrieve information from Browser 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 Browser:

```json
{
