WHAT IT DOES

What create_dns_record does on Vultr MCP

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

RISK

Why create_dns_record is rated Medium

This tool creates DNS records, which modifies domain configuration reversibly. While DNS changes can have significant operational impact (redirecting traffic, affecting service availability), they are not irreversible (records can be deleted/modified). This is a Write operation rather than Execute because it doesn't run arbitrary code or commands—it configures infrastructure through a defined API.

From the tool's definition Tool name contains 'create' and description states 'Create a new DNS record for a domain', indicating creation of new data.

create_dns_record Rate-limited

create_dns_record stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
