## What it does

An agent can check domain availability and pricing, suggest available names, connect an existing domain, and retrieve the DNS records it needs. It can also identify the DNS provider and track a connection until HTTPS is live. The server exposes twenty tools through one MCP endpoint.

The service runs at `https://mcp.customdomain.ai/mcp`; there is no local server to install or keep running. A domain-purchase tool is included, but it is currently disabled on the hosted service. You can check options there, but you cannot complete a purchase with that tool.
