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.
Transport: Streamable HTTP. Authentication: OAuth 2.1 (handled automatically by supported clients).
Pricing: MCP server access is free. Standard Muumuu Domain registration fees apply when purchasing domains.
Choose your client below.
Then run /mcp inside Claude Code and select Authenticate to complete the OAuth flow.
Settings → Connectors → Add custom connector → enter:
OAuth is handled automatically by Claude.
Add to .cursor/mcp.json:
See the Gemini CLI MCP server documentation for adding remote MCP servers.
For clients that only support stdio transport, use mcp-remote:
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:
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.
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.
