WHAT IT DOES

What porkbun_create_dns does on Access

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

WHY IT NEEDS A POLICY

Why porkbun_create_dns needs a policy

This tool creates DNS records which persist and affect domain routing immediately. While creations are typically reversible (DNS records can be deleted), the immediate live effect and potential to disrupt domain services (by creating conflicting or malicious records) elevates severity to high. The tool does not delete data (Destructive) nor move money (Financial), so Write is the correct category.

From the tool's definition Tool description explicitly states "Create a new DNS record" and "the record is live immediately after creation", indicating data creation with immediate side effects.
