WHAT IT DOES

What update_dns_record does on 20i MCP Server

AI agents use update_dns_record to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment.

RISK

Why update_dns_record is rated Medium

DNS record updates are Write operations because they modify domain configuration data reversibly (records can be changed back or deleted). However, severity is high because misconfigured DNS records can cause service outages, email delivery failures, or enable domain hijacking if an attacker gains control.

From the tool's definition Tool performs 'Add or update DNS records' - a reversible modification operation that creates or changes data. The verb 'update' combined with DNS record management indicates write capability.
