Install

Overview

Description from the maker (original English)

Check domains, read domains and DNS zones, and update DNS zone records in Realtime Register.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Developer tools

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 14 things (tools) realtimeregister_check_domain, realtimeregister_list_domains, realtimeregister_get_domain, realtimeregister_get_domain_zone …
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • realtimeregister_check_domain

    Check whether a domain name is available to register, with its price if it is premium. Check one name per call and wait at least one second before the next call (vendor acceptable use policy). Realtime Register API: GET /domains/{domainName}/check.

  • realtimeregister_list_domains

    List the domains in the customer account, with expiry dates, name servers and status. Use limit and offset to page through them. Realtime Register API: GET /domains/.

  • realtimeregister_get_domain

    Get one domain in the customer account: registrant, contacts, name servers, status, expiry and auto-renew settings. Realtime Register API: GET /domains/{domainName}.

  • realtimeregister_get_domain_zone

    Get the DNS zone that belongs to a domain, with its records and SOA settings. Realtime Register API: GET /domains/{domainName}/zone.

  • realtimeregister_list_dns_zones

    List the DNS zones in the customer account. Use limit and offset to page through them. Realtime Register API: GET /dns/zones/.

  • realtimeregister_get_dns_zone

    Get one DNS zone by id, with its records and SOA settings. Read the zone before any update. Realtime Register API: GET /dns/zones/{id}.

  • realtimeregister_list_contacts

    List the contacts (registrant and admin records) of the customer account. Realtime Register API: GET /customers/{customer}/contacts/.

  • realtimeregister_get_contact

    Get one contact by handle. Realtime Register API: GET /customers/{customer}/contacts/{handle}.

  • realtimeregister_list_hosts

    List the host objects (name servers with glue addresses) in the customer account. Realtime Register API: GET /hosts/.

  • realtimeregister_get_host

    Get one host object by its name, such as ns1.example.com. Realtime Register API: GET /hosts/{hostName}.

  • realtimeregister_get_credit

    Get the prepaid credit balance of the customer account. Domain orders are paid from this balance. Realtime Register API: GET /customers/{customer}/credit.

  • realtimeregister_get_process

    Get the status of an asynchronous process, such as a domain update or a DNS zone change. Use the id from a write call's response. Realtime Register API: GET /processes/{id}.

  • realtimeregister_get_tld_info

    Get the registry metadata for a TLD, such as its rules and the fields it requires. Realtime Register API: GET /tlds/{tld}/info.

  • realtimeregister_update_dns_zone

    Change the SOA settings, name servers or records of a DNS zone. Read the zone first with realtimeregister_get_dns_zone and send only the fields you change. Changes reach the public internet after DNS caches expire. Send writes one at a time, at least one second apart (vendor acce

Common questions

Is Realtime Register MCP by usefulapi safe?

It passed 3 of 3 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

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

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

Realtime Register MCP by usefulapi

Use your Realtime Register account from Claude, Cursor, or any MCP client. Check domain availability, read domains and DNS zones, and update DNS zone records. Hosted, no local install: connect with your own credentials.

Live endpoint: https://realtime-register.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://realtime-register.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http realtime-register https://realtime-register.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "realtime-register": { "url": "https://realtime-register.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Realtime Register credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/realtime-register/

On first connect you provide a Realtime Register API key (created on your profile page; it is shown only once) and your customer handle (the account name in the API paths). The server validates it and stores it per user. No keys go in config files.
