Domain MCP agent

Why manage domains through MCP?

Registrar APIs cover dozens of jobs, but each command has its own parameters, response shape, and edge cases. Working with the API directly takes time and leaves plenty of room for mistakes.

domain-mcp gives your AI client a smaller, typed toolset. Ask it to check availability, update DNS, review renewals, or manage a portfolio without memorizing Dynadot's API.

Without domain-mcp	With domain-mcp
Search API docs for every task	Describe the outcome in plain language
Build and maintain registrar scripts	Use the same MCP tools from supported clients
Handle inconsistent response envelopes	Get results in a consistent format
Expose every API command as a separate tool	Keep context small with 10 composite tools

Quick start

You need Node.js 18 or newer and a Dynadot API key.

Add the server to your MCP client:

{
  "mcpServers": {
    "domain-mcp": {
      "command": "npx",
      "args": ["-y", "domain-mcp"],
      "env": {
        "DYNADOT_API_KEY": "your-api-key"
      }
    }
  }
}

Restart the client, then try:

List my domains that expire in the next 60 days.

For client-specific setup, shared HTTP transport, environment options, and troubleshooting, read the domain-mcp package guide.

How domain-mcp works

You describe a domain task
          │
          ▼
Claude, Cursor, or another MCP client
          │  selects a tool and operation
          ▼
domain-mcp validates and transforms the request
          │  calls the Dynadot API
          ▼
The result returns to your AI client

The server groups related operations into composite tools, so clients load a small set of tools instead of more than 100 separate definitions.

Domain management features

Area	What you can do
Domains	Search, register, renew, delete, lock, push, and inspect domains
DNS	Read and update DNS records, forwarding, parking, and email settings
Nameservers	Create, edit, list, and assign nameservers
Transfers	Start transfers, check status, and manage authorization steps
Contacts	Create and maintain WHOIS contact records
Portfolio	Work with folders, account data, bulk settings, and renewals
Aftermarket	List domains, manage auctions, bids, and marketplace operations
Agent workflows	Generate domain ideas, run portfolio audits, and diagnose DNS issues

The server groups Dynadot operations into 10 composite tools, with additional tools for domain checks, name generation, and tool discovery. Zod validates inputs. Responses follow a consistent format, and errors explain what went wrong.

What's inside

This repository is a pnpm workspace with two related packages:

Package	Best for	Distribution
domain-mcp	Claude, Cursor, Claude Desktop, Zed, and other MCP clients	npm
domain-agent-kit	Agent Plugins v1 hosts, including Hermes and Claude Code	Portable plugin with optional Claude safety adapter

packages/
├── domain-mcp/        # TypeScript MCP server published to npm
└── domain-agent-kit/  # Portable Agent Plugin built on domain-mcp

Domain MCP examples

Once connected, you can ask your client to:

• “Check whether example.com is available and show similar names.”
• “Add an A record for example.com and point it to 203.0.113.10.”
• “Find domains expiring this quarter and group them by urgency.”
• “Enable auto-renew for every unlocked .com domain.”
• “Show the current nameservers and WHOIS contacts for example.com.”

Your client should still ask before destructive or paid operations. The portable plugin defines that approval and read-back contract, and its optional Claude Code adapter adds a native confirmation hook for selected irreversible actions.
