Muumuu Domain MCP Server

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

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:

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

OpenAI Codex CLI

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:

{
  "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:

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

get-domain-purchase-status	Poll the progress of a purchase started by purchase-domain.

Domain management

Tool	Description

update-me-domain	Turn credit-card auto-renewal on or off for an owned domain. write

DNS management

Tool	Description
list-me-dns-records	List the DNS records of an owned domain, addressed by domain ID.
