Manage domains, DNS, contacts, registrar locks, and view SSL certificates and pricing via the Namecheap API.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@namecheap-api-mcp check availability of example.com"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP server for the Namecheap API — 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 toolkit by Rex Jones — AI-powered SEO and social media tooling for agencies and businesses.
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.

Go to Profile → Tools → Namecheap API Access 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).

Tool | Description |
| Verify credentials + IP whitelist; returns the account balance summary. |
| List domains with expiry, lock, auto-renew, and WhoisGuard status (paged/searchable). |
| Detailed info for one domain. |

| Email forwarding rules. |
| Namecheap pricing for a product type (cache the results). |
| SSL certificates with type, host, status, expiry. |
Tool | Description |
| Replace all host records (destructive: omitted records are deleted — send the full set). |
| Switch a domain to Namecheap's default nameservers. |
| Point a domain at custom nameservers. |
| Set email forwarding rules. |
| Lock / unlock a domain at the registrar. |
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.
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.

Verify the Namecheap API connection and credentials. Returns the account balance summary — a lightweight call that confirms the API user, key, and IP whitelist are all working.
Inputs: no named parameters.
Check availability (and premium pricing) for one or more domains. Max 50 per call.
Inputs: domains (required).
Get all DNS host records (A, AAAA, CNAME, MX, TXT, URL, etc.) for a domain.
Inputs: domain (required).
Get the Registrant, Tech, Admin, and AuxBilling contact details for a domain.
Inputs: domain (required).
Get detailed info for one domain: status, created/expiry dates, WhoisGuard, DNS provider, and modification rights.
Inputs: domain (required).
Get email forwarding settings (mailbox → forward-to) for a domain.
Inputs: domain (required).
Get the nameservers associated with a domain, and whether it uses Namecheap's default DNS.
Inputs: domain (required).
Get Namecheap pricing for a product type (e.g. DOMAIN register/renew/transfer). Cache results — this is a heavy endpoint.
Inputs: product_type, product_category, action_name, product_name.
Get the registrar lock status for a domain.
Inputs: domain (required).
List domains in the account, with creation/expiry dates, lock status, auto-renew, and WhoisGuard status. Supports paging and search.
Inputs: list_type, search_term, page, page_size, +1 more.
List SSL certificates in the account, with type, host name, status, and expiry.
Inputs: list_type, search_term, page, page_size.
Point a domain at custom nameservers. NOTE: Namecheap host records, URL/email forwarding stop working while custom nameservers are in use.
Inputs: domain (required), nameservers (required).
Switch a domain to Namecheap's default (BasicDNS) nameservers. Required for Namecheap host records, URL/email forwarding.
Inputs: domain (required).
Replace ALL DNS host records for a domain. WARNING: this is destructive — Namecheap deletes any record not included here, so you must pass the COMPLETE desired record set (call get_dns_hosts first, merge your changes, then send everything). Switches the domain to Namecheap DNS if needed.
Inputs: domain (required), records (required), email_type.
Set email forwarding rules for a domain. Replaces the full forwarding set (pass all rules you want to keep).
Inputs: domain (required), forwards (required).
Lock or unlock a domain at the registrar (theft protection). Unlock before initiating an outbound transfer.
Inputs: domain (required), action.

Scored across 16 tools
Each tool has a clearly distinct purpose: connection check, domain availability, DNS management, contacts, info, pricing, registrar lock, etc. There is no overlap or ambiguity between any two tools.
All tools follow a consistent verb_noun pattern in snake_case (e.g., check_domains, get_dns_hosts, set_registrar_lock). The verbs are uniform (check, get, list, set) and there are no deviations.
With 16 tools, the set feels well-scoped for a domain and DNS management API. It covers essential operations without being overwhelming, and each tool adds clear value.
The tool set covers many aspects (DNS, contacts, pricing, SSL listing), but lacks fundamental lifecycle operations like domain registration, renewal, or transfer. This is a notable gap given the server's domain management focus.
