## Why dns_health_check is rated Low

This tool retrieves and reports on DNS health status and configuration state. It has no side effects, creates no data modifications, executes no arbitrary code, and poses minimal risk if misused by an agent — at worst it returns diagnostic information. The severity is low because DNS health analysis is informational only and cannot damage systems or data.

From the tool's own definition: "Tool performs 'Analyze DNS configuration for common issues' — a diagnostic/query operation that examines DNS settings without modifying them."

## Use case

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