The Muumuu Domain MCP Server enables natural language management of domains and DNS via AI assistants like Claude and Cursor.
Domain Search & Purchase: Search availability and pricing, get a purchase quote with a short-lived token, purchase domains (irreversible, charges credit card), and check purchase status.
Domain Management: List and view details of owned domains (including contract period, auto-renewal status, nameservers), with filtering and pagination; toggle credit-card auto-renewal.
DNS Management: List, create, update, and delete DNS records (A, AAAA, CNAME, MX, TXT, NS, ALIAS, SRV, CAA) for owned domains.
Personal Access Tokens: List and revoke personal access tokens.

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.
https://mcp.muumuu-domain.com/mcpTransport: Streamable HTTP. Authentication: OAuth 2.1 (handled automatically by supported clients).
Related MCP server: Whodis MCP Server
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.

Add to .cursor/mcp.json:
{
"mcpServers": {
"muumuu": {
"url": "https://mcp.muumuu-domain.com/mcp"
}
}
}codex mcp add muumuu --url https://mcp.muumuu-domain.com/mcpSee the Gemini CLI MCP server documentation for adding remote MCP servers.
For clients that only support stdio transport, use mcp-remote:
{
"mcpServers": {
"muumuu": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://mcp.muumuu-domain.com/mcp"]
}
}
}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-onlyIn 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.
Tool | Description |
| Check availability and pricing of domain candidates across TLDs. Does not reserve anything. |
| Get a signed quote — final price, availability, and a short-lived purchase token — before buying. |
| Execute a purchase with a quote token. write / destructive — charges the registered credit card. |
| Poll the progress of a purchase started by |
Tool | Description |
| List domains owned by the authenticated account, filtered by state or FQDN, paginated. |
| Fetch one owned domain in full: contract period, auto-renewal status, nameservers. |
| Turn credit-card auto-renewal on or off for an owned domain. write |
Tool | Description |
| List the DNS records of an owned domain, addressed by domain ID. |
| The same listing, addressed by FQDN when the domain ID is unknown. |
| Add a record — A, AAAA, CNAME, MX, TXT, NS, ALIAS, SRV, or CAA. write |
| Change the value or priority of an existing record. write |
| Remove a record from the zone. write / destructive |
Tool | Description |
| List the personal access tokens issued for the account. |
