WHAT IT DOES

What domain_dns_add does on CoWork OS

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

RISK

Why domain_dns_add is rated Medium

Adding a DNS record is a reversible write operation that modifies domain settings. It is not destructive (records can be deleted/updated later), not financial, and not code execution. However, DNS misconfigurations could redirect traffic or disrupt services, warranting medium severity given the potential blast radius if an agent misconfigures critical DNS entries (e.g., MX, CNAME records).

From the tool's definition Tool name 'domain_dns_add' and description 'Add a DNS record to a domain' indicate creation of a new DNS record, which modifies domain configuration.

RECOMMENDED RULE

The rule that runs domain_dns_add safely

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

domain_dns_add Rate-limited

domain_dns_add 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.
