Common questions

Is Namecheap API MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: NAMECHEAP_API_USER, NAMECHEAP_API_KEY, NAMECHEAP_CLIENT_IP

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

namecheap-api-mcp

MCP server for the [Namecheap API](https://www.namecheap.com/support/api/intro/) — manage domains, DNS, contacts, registrar locks, and view SSL certificates and pricing, straight from your AI assistant.

Built for Claude Code and any MCP-compatible AI tool.

Part of [The SEO Engine](https://lanternrow.com/seo-engine/) toolkit by Rex Jones — AI-powered SEO and social media tooling for agencies and businesses.

Safety model

This server ships read + safe-write tools only. It can read your account and change DNS / nameserver / forwarding / lock configuration (all reversible), but it deliberately excludes anything that spends money or is irreversible: no domain registration, renewal, reactivation, transfers, SSL purchase/activation, add-funds, or account/address mutation. You can fork and add those if you need them.

Quick start

1. Enable Namecheap API access

Go to Profile → Tools → [Namecheap API Access](https://ap.www.namecheap.com/settings/tools/apiaccess/) and toggle it ON. (Production access requires account eligibility: 20+ domains, OR a $50+ balance, OR $50+ lifetime spend.)
Copy your API key.
Whitelist the public IPv4 of the machine that will run this server (the API rejects any non-whitelisted IP with error 1011150).

2. Configure your MCP client

"mcpServers": { "namecheap": { "command": "npx", "args": ["-y", "namecheap-api-mcp"], "env": { "NAMECHEAP_API_USER": "your_username", "NAMECHEAP_API_KEY": "your_api_key", "NAMECHEAP_CLIENT_IP": "your.whitelisted.ip.v4" } } } }

Option: clone and build

git clone https://github.com/lanternrow/namecheap-api-mcp.git

cd namecheap-api-mcp npm install npm run build

Then point your client at node /path/to/namecheap-api-mcp/dist/index.js. For local credentials you can keep a gitignored .env (copy .env.example) and launch with Node's native flag: node --env-file=.env dist/index.js.

Environment variables

Variable	Required	Description
`NAMECHEAP_API_USER`	Yes	Your Namecheap account username (API user).
`NAMECHEAP_API_KEY`	Yes	API key from Profile → Tools → API Access. Secret.
`NAMECHEAP_CLIENT_IP`	Yes	The whitelisted public IPv4 of this machine.
`NAMECHEAP_USERNAME`	No	Defaults to `NAMECHEAP_API_USER`; differs only for reseller sub-users.
`NAMECHEAP_ENVIRONMENT`	No	`production` (default) or `sandbox`.

Tools

Read

Tool	Description
`check_connection`	Verify credentials + IP whitelist; returns the account balance summary.
`list_domains`	List domains with expiry, lock, auto-renew, and WhoisGuard status (paged/searchable).
`get_domain_info`	Detailed info for one domain.
`check_domains`	Check availability + premium pricing (up to 50 at once).
`get_domain_contacts`	Registrant / Tech / Admin / AuxBilling contacts.
`get_registrar_lock`	Registrar lock status.
`get_dns_hosts`	All DNS host records for a domain.
`get_nameservers`	Nameservers and whether Namecheap DNS is in use.
`get_email_forwarding`	Email forwarding rules.
`get_pricing`	Namecheap pricing for a product type (cache the results).
`list_ssl_certificates`	SSL certificates with type, host, status, expiry.

Safe writes (configuration only — no charges)

Tool	Description
`set_dns_hosts`	Replace all host records (destructive: omitted records are deleted — send the full set).
`set_default_dns`	Switch a domain to Namecheap's default nameservers.
`set_custom_nameservers`	Point a domain at custom nameservers.
`set_email_forwarding`	Set email forwarding rules.
`set_registrar_lock`	Lock / unlock a domain at the registrar.

Notes & gotchas

`set_dns_hosts` is destructive by API design. Namecheap's setHosts deletes every record not included in the call. Always read current records first (get_dns_hosts), merge your change, then send the complete set.
Errors return HTTP 200. The Namecheap API signals failure in the XML body (Status="ERROR"), not the HTTP status. This server parses that and throws a real error with the Namecheap error number + message.
IPv4 only for the whitelisted client IP.

Security

Credentials are read from environment variables only — never hard-coded, logged, or written to disk by this server.
The API key travels in the query string (Namecheap's design); this server never logs the request URL or key, and error messages surface only the Namecheap error number and text.
