Muumuu Domain MCP server

by pepabo · official

Let your AI search for domains, check prices, manage your domains, and edit DNS records for you.

This is the official helper from Muumuu Domain, a domain registration service run by GMO Pepabo in Japan. Once you connect it, your AI assistant can look up domain names, check prices, and help you manage the domains and DNS records you already own. It is handy if you buy or manage domains and would rather just ask in plain words than click around a website.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper that gives your AI a new skill or a connection to an outside service. This one connects your AI to Muumuu Domain, so it can look things up and make changes on your account when you ask. You do not install anything on your computer here. It runs online, and you just add its web address to your AI app.

What this MCP server does

You ask your AI something like whether a domain name is free or what your DNS records look like. The AI sends that request to this helper, which talks to Muumuu Domain on your behalf. Muumuu Domain sends back the answer, and the AI shows it to you in the chat in normal words. If you ask it to make a change, like adding a DNS record, the helper does that too, but only after you confirm.

Flow diagram: you ask your AI “Is example.com available and how much?”, the Muumuu Domain MCP server connects it to Muumuu Domain, and you get back answers in your chat.

What you can do with it

Check whether a domain name is available and see its price
Get a final quote before buying a domain
Buy a domain using your saved card (this charges money)
List the domains you already own and see their details
Turn auto-renewal on or off for a domain
List, add, change, or remove DNS records for a domain
List or revoke your personal access tokens

What it gives back to you

You get answers in the chat: lists of domains or DNS records, prices, availability, renewal dates, and auto-renewal status. When you buy a domain, it tells you the progress of that purchase. When you change something, like a DNS record, it confirms what it did. Everything shows up as normal text in your conversation.

Before you start

What you need

A Muumuu Domain account
An MCP-compatible AI app, such as Claude Desktop, Claude Code, Cursor, OpenAI Codex CLI, or Gemini CLI
A credit card on file if you plan to buy domains

Good to know

Some actions really change things: buying a domain charges your card, and deleting a DNS record or revoking a token cannot be undone, so always read the confirmation before you say yes.

Install it with your AI

Add Muumuu Domain MCP server to your AI, no technical skills needed

You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.

Sign in to get the install prompt

Members get a ready-made prompt that lets the Claude desktop app check Muumuu Domain MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
