Works with Claude, with some setup first

Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Domainavail for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "domainavail": { "command": "npx", "args": [ "-y", "@reneturcios/domainavail", "mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the Domainavail tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install Node.js (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

    node -v
    • A version number such as v26.13.1 = installed, skip this step
    • "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
    How to open Terminal

    Mac: press ⌘ + Space, type Terminal, press Enter

    Windows: open Start, type Windows PowerShell, then Open

    Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed

    Open the Node.js download page ↗

    When it’s done, close Terminal, open it again and run the same command. You should see a version number: node -v

    Install once; it works for everything that needs Node.js

  2. Open the Claude desktop app’s settings file

Common questions

Is Domainavail 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 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 11 days ago, and the latest version (0.1.0) reached the registry 11 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
