WHAT IT DOES

What dynadot_set_default_ns does on Dynadot

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

RISK

Why dynadot_set_default_ns is rated Medium

This tool creates or modifies account-level DNS configuration that persists across multiple domains. While it does not delete data and does not move money, it writes configuration that affects domain behavior. The high severity is justified because misconfiguration of nameservers could redirect domains to attacker-controlled infrastructure, disrupting services and enabling phishing or interception attacks.

From the tool's definition "Set default nameservers for new domains" - this modifies DNS configuration settings that will apply to future domain registrations, creating a persistent change to account defaults.

RECOMMENDED RULE

The rule that runs dynadot_set_default_ns safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Dynadot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For dynadot_set_default_ns, this is the rule to start with:

dynadot_set_default_ns Rate-limited

dynadot_set_default_ns 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.
