WHAT IT DOES

What kinsta.domains.add does on Kinsta MCP Server

AI agents use kinsta.domains.add to create or update resources in Kinsta MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kinsta MCP Server environment.

WHY IT NEEDS A POLICY

Why kinsta.domains.add needs a policy

This is a Write operation because it creates or modifies infrastructure configuration reversibly—adding a domain can be undone by removing it. It does not execute arbitrary code, delete data irreversibly, or move money. Severity is medium because misconfiguration could affect site accessibility or DNS routing, with moderate blast radius if an AI agent adds incorrect domains to production environments.

From the tool's definition Tool description states 'Add a custom domain to an environment.' The verb 'add' indicates creating/modifying configuration by attaching a new domain resource to a Kinsta environment.
