## Why get_platform_fonts is rated Low

This is a pure data retrieval operation that queries font rendering information from a DOM element. There are no side effects, no code execution, no data modification, and no irreversible actions. It fits the 'Read' category as it simply queries and returns existing information about platform fonts.

From the tool's own definition: "The tool 'get_platform_fonts' retrieves 'Information about platform fonts used to render text nodes' for a specified DOM element. It takes a node_id as input and returns data without modifying, deleting, or executing operations."

## Use case

AI agents call get_platform_fonts to retrieve information from Chrome Devtools 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:

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