Overview

AI-generated overview

Official remote MCP server for Muumuu Domain that lets an assistant search and buy domains, manage owned domains and contracts, and edit DNS records.

What you can do
  • Search domain candidates across TLDs and get signed purchase quotes
  • Buy domains with a quote token and poll purchase status
  • List and inspect owned domains, including contract period, auto-renewal and nameservers
  • Turn credit-card auto-renewal on or off for a domain
  • List, create, update and delete DNS records (A, AAAA, CNAME, MX, TXT, NS, ALIAS, SRV, CAA)
  • List and revoke personal access tokens on the account
When to use it
Useful when you want to check domain availability and pricing, register a domain, review renewals and contracts, or change DNS records for domains you own at Muumuu Domain, all from an AI assistant conversation.
Requirements
A Muumuu Domain account and an MCP-compatible client that supports remote Streamable HTTP with OAuth 2.1; the endpoint is remote, so no local runtime is needed, though a stdio bridge via mcp-remote is possible for stdio-only clients. Network access is required.
Before you install
Purchases charge the registered credit card, and purchase, DNS record changes, auto-renewal changes and token revocation all modify account state; DNS deletion and token revocation cannot be undone. Confirm before any write or destructive tool call. Access to the server is free, but standard registration fees apply to purchases.

Installation

In SourceWeft

  1. Open Muumuu Domain MCP Server in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.pepabo%2Fmuumuu-domain-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Muumuu Domain MCP Server

日本語版 README はこちら / Japanese README

The official remote Model Context Protocol (MCP) server for Muumuu Domain — a domain registration service operated by GMO Pepabo, Inc.

Search and register domains, manage owned domains and contracts, and configure DNS records — all through natural language conversations with AI assistants.

First remote MCP server in the Japanese domain registrar industry.

Endpoint

https://mcp.muumuu-domain.com/mcp

Transport: Streamable HTTP. Authentication: OAuth 2.1 (handled automatically by supported clients).

Features

  • Domain search & registration — check availability, view pricing, register domains
  • Domain management — list and inspect owned domains
  • DNS management — list, create, update, and delete DNS records
  • Contract management — review contract list (renewal dates, auto-renewal status) and details

Pricing: MCP server access is free. Standard Muumuu Domain registration fees apply when purchasing domains.

Quick Start

Choose your client below.

Claude Code

bash
claude mcp add --transport http muumuu https://mcp.muumuu-domain.com/mcp

Then run /mcp inside Claude Code and select Authenticate to complete the OAuth flow.

Claude Code MCP docs

Claude Desktop / claude.ai

Settings → Connectors → Add custom connector → enter:

https://mcp.muumuu-domain.com/mcp

OAuth is handled automatically by Claude.

Cursor

Add to .cursor/mcp.json:

json
{  "mcpServers": {    "muumuu": {      "url": "https://mcp.muumuu-domain.com/mcp"    }  }}

OpenAI Codex CLI

bash
codex mcp add muumuu --url https://mcp.muumuu-domain.com/mcp

Gemini CLI

See the Gemini CLI MCP server documentation for adding remote MCP servers.

Local stdio bridge (advanced)

For clients that only support stdio transport, use mcp-remote:

json
{  "mcpServers": {    "muumuu": {      "command": "npx",      "args": ["-y", "mcp-remote", "https://mcp.muumuu-domain.com/mcp"]    }  }}

Introspection-only mode (registry tooling)

For MCP registries (e.g. Glama) that index the tool surface in a headless build environment where an interactive OAuth flow cannot complete, the CLI also supports a stdio-only introspection mode:

bash
node bin/muumuu-mcp.js --introspect-only

In this mode the CLI serves the static tool manifest over stdio. It does not make any network calls, does not read the Authorization header, and tools/call always returns isError: true. Do not use this mode for real traffic.

Tools

The server exposes 14 tools. Tools marked write change account state; those marked destructive cannot be undone — clients should confirm with the user before calling them.

Domain search & purchase

ToolDescription
search-domainsCheck availability and pricing of domain candidates across TLDs. Does not reserve anything.
quote-domain-purchaseGet a signed quote — final price, availability, and a short-lived purchase token — before buying.
purchase-domainExecute a purchase with a quote token. write / destructive — charges the registered credit card.
get-domain-purchase-statusPoll the progress of a purchase started by purchase-domain.

Domain management

ToolDescription
list-me-domainsList domains owned by the authenticated account, filtered by state or FQDN, paginated.
get-me-domainFetch one owned domain in full: contract period, auto-renewal status, nameservers.
update-me-domainTurn credit-card auto-renewal on or off for an owned domain. write

DNS management

ToolDescription
list-me-dns-recordsList the DNS records of an owned domain, addressed by domain ID.
list-me-dns-records-by-fqdnThe same listing, addressed by FQDN when the domain ID is unknown.
create-me-dns-recordAdd a record — A, AAAA, CNAME, MX, TXT, NS, ALIAS, SRV, or CAA. write
update-me-dns-recordChange the value or priority of an existing record. write
delete-me-dns-recordRemove a record from the zone. write / destructive

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
