unlock_domain · InstaDomain MCP: Risk & Policy

WHAT IT DOES

What unlock_domain does on InstaDomain

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

WHY IT NEEDS A POLICY

Why unlock_domain needs a policy

Unlocking a domain removes the transfer lock, enabling the domain to be transferred away from the current registrar. This is a reversible write action (the lock can be re-applied), but it has high blast radius because it exposes the domain to unauthorized transfers if misused, which could lead to domain hijacking.

From the tool's definition Remove the registrar transfer lock. Requires a transfer_token from verify_transfer_code.

Verdict

unlock_domain Rate-limited

unlock_domain 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.
