## Why get_as112_data is rated Low

This tool performs a read-only retrieval operation on DNS analytics data from AS112. There are no side effects, data modifications, or external operations triggered. The blast radius of misuse is minimal—an agent could retrieve DNS diagnostics data but cannot modify, delete, or execute operations. Classified as Read with low severity.

From the tool's own definition: "The tool description explicitly states 'Retrieve AS112 DNS sink hole data', indicating data retrieval without modification. This is a query operation for analyzing DNS patterns."

## Use case

AI agents call get_as112_data to retrieve information from Cloudflare 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 Cloudflare:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_as112_data": {}
  }
}
