Registry nameio.github.CloudCorpRecords/domainavail

Overview

Description from the maker (original English)

Bulk domain availability: DNS, RDAP and WHOIS checks with registrar prices for the free names.

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 on your computer
  • Transport: stdio
  • Category: Other

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "domainavail": {
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/domainavail",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add domainavail -- npx -y @reneturcios/domainavail mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "domainavail": {
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/domainavail",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "domainavail": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/domainavail",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Domainavail 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?

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 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 (0.1.0) reached the registry 3 days 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, Docker on your computer.

What can I use instead?

domainavail

You have a list of names you like. Which of them could you actually register? domainavail answers that for a whole list at once: hand it candidate names and it walks each one through a series of public checks, tells you which names look free, which are taken, and — for the free ones — what they cost and where to buy them. It is strictly read-only: it never registers, reserves or changes anything.

How a name is checked

Names are normalised first (scheme and path stripped, lowercased). A name without a dot is expanded over each configured TLD; a full domain is checked as-is. Each expanded name then goes through a funnel:

  1. DNS delegation — if the name has NS records it is delegated, so it is taken. ENOTFOUND / ENODATA mean not delegated; other DNS errors leave the name on the unknown path.
  2. RDAP — a 200 means the name is registered (taken); the expiration event is reported as expires, and a pending-delete status adds the note being deleted; may become available soon. A 404 means the name looks free.
  3. WHOIS fallback — used when the TLD has no RDAP or RDAP fails. Text matching No match / NOT FOUND / No Data Found means free-looking; a record means taken; a WHOIS failure means unknown.
  4. Registrar confirmation — a free-looking name stays likely_available unless a configured registrar confirms it. Registrars are asked in the order Name.com → Cloudflare → Spaceship → Porkbun, until one answers definitively: then the name becomes available (with premium: true when the registrar says premium, and its price when given), reserved, or taken.

Possible statuses: available, likely_available, taken, reserved, unknown.

The output is one JSON object: a summary with counts per status, results in input order (except saved domains, which are marked saved: true and listed first), a skipped list for inputs that were not domain names or that fell over the expansion cap, and warnings. With details: true each result also carries evidence — the per-step record of what DNS, RDAP, WHOIS and the registrar said.

Configuration

All configuration is via DOMAINSCOUT_* environment variables:

  • DOMAINSCOUT_TLDS — TLDs for expanding bare names (default com,net,ai). The per-call tlds argument overrides this.
  • DOMAINSCOUT_REGISTRARS — comma list filtering which registrars are used for offers and confirmation.
  • DOMAINSCOUT_MAX_CONCURRENCY — parallel checks (default 10).
  • DOMAINSCOUT_PER_HOST_CONCURRENCY — default 2. Parsed but not separately enforced in this rebuild (a labelled simplification).
  • DOMAINSCOUT_TIMEOUT_MS — per-request timeout (default 10000).
  • DOMAINSCOUT_MAX_DOMAINS — expansion cap (default 500, hard max 10000). Excess names go to skipped with the reason over DOMAINSCOUT_MAX_DOMAINS.
  • DOMAINSCOUT_CONFIRM_MAX — most names confirmed with registrars per call (default 50).
  • DOMAINSCOUT_DNS — DNS step on/off (default on), and DOMAINSCOUT_DNS_SERVERS — custom DNS servers.
  • DOMAINSCOUT_PRICES — price offers on/off (default on).
  • DOMAINSCOUT_AFFILIATE — accepted (default on); buy links here are plain links and carry no affiliate templates.
  • Registrar keys: DOMAINSCOUT_NAMECOM_USERNAME / DOMAINSCOUT_NAMECOM_TOKEN, DOMAINSCOUT_CLOUDFLARE_ACCOUNT_ID / DOMAINSCOUT_CLOUDFLARE_API_TOKEN, DOMAINSCOUT_SPACESHIP_API_KEY / DOMAINSCOUT_SPACESHIP_API_SECRET, DOMAINSCOUT_PORKBUN_API_KEY / DOMAINSCOUT_PORKBUN_SECRET_KEY. Each registrar's keys are sent only to that registrar.

Prices come from the Porkbun public pricing API and a Cloudflare pricing mirror, ordered cheapest first. An offer is {registrar, price, renewal?, url}.

Endpoint provenance

The RDAP lookup uses https://rdap.org/domain/ (endpoint choice labelled). The registrar confirmation endpoints and the two price-source URLs are reconstructions, labelled as such; the Cloudflare search URL https://www.cloudflare.com/domains/search/?q= is the documented example, and the Porkbun checkout URL is our rendering of the same idea.

Tools

  • check_domains — checks whether domain names are free to register, with prices and where to buy the free ones. Arguments: domains (required array of strings, 1–1,000 entries), tlds (optional array of strings), confirm (optional boolean, default true), details (optional boolean, default false), saved (optional array of strings). Validation fails with domains must be an array of 1 to 1000 names; entries that are empty after normalising go to skipped with the reason not a domain name.

CLI

npx @reneturcios/domainavail check_domains '{"domains":["example","widget.com"],"details":true}'

npx @reneturcios/domainavail --version

Output is the tool's result text (the JSON described above). Exit codes: 0 on success, 1 on a runtime error (including validation), 2 on a usage error.

MCP server

npx -y @reneturcios/domainavail mcp

MCP client config:

{

"mcpServers": { "domainavail": { "command": "npx", "args": ["-y", "@reneturcios/domainavail", "mcp"] } } }
