## Why batch_dns_update is rated Medium

This tool creates or modifies DNS records across multiple domains, which is a reversible write operation. However, the severity is elevated to 'high' due to the blast radius: misconfigured DNS records can disrupt service availability, email delivery, and security posture across many domains simultaneously. The batch nature compounds the risk.

From the tool's own definition: "Tool name and description explicitly state 'Update DNS records' for 'multiple domains at once'. DNS updates are modifications to critical infrastructure configuration that affect domain routing and service availability."

Risk signals: Bulk/mass operation — affects multiple targets
