Overview

AI-generated overview

OrbitFour lets an assistant check domain availability and live registry pricing, search for available names, and review TLD and transfer requirements.

What you can do
Check exact domain names for availability and per-year registration, renewal and transfer prices, premium names included, up to 10 per call. Search domain names from a free-text idea, brand or phrase, with top picks showing the name as typed and on .com, .net and .org or chosen extensions. Look up TLD requirements: prices, ICANN fee, term lengths, WHOIS privacy, eligibility restrictions and related rules. Check whether names can be transferred to OrbitFour and quote the full first-term transfer price, up to 5 per call.
When to use it
Useful when choosing or validating a domain name for a project or brand, comparing extension costs, or checking whether an existing domain can be transferred before starting a purchase or transfer.
Requirements
Remote endpoint at the provider's site over streamable HTTP; no packages, environment variables or headers are declared. Network access to the endpoint is needed.
Before you install
The tools are described as read-only lookups, but they query live registries and return pricing and eligibility details that may change; confirm final prices and terms with the registrar before buying or transferring. No authentication is declared.

Installation

In SourceWeft

  1. Open OrbitFour in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.orbitfour%2Fdomains/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

check_domain

Check domain availability and price

Look up exact domain names: whether each can be registered now, and its per-year registration, renewal and transfer price in USD, premium names included, from a live registry check. Use it for names you already have and to confirm a search_domains suggestion. Up to 10 names per call; read-only. available is true, false, or null (the registry could not be asked; not the same as taken). An unavailable name says why in reason: taken, reserved, unavailable or unknown. purchasable is false for an available name OrbitFour can't sell now, and for a null one, and purchase_blocker says why. first_term is the shortest term (min_years: .ai is 2) and its total with the ICANN fee. A malformed name or an extension OrbitFour doesn't sell comes back with an error field. pricing_source says where the registration price came from: "registry" is a live quote for that name, "baseline" is the extension's standard rate and final for the name (the extension has no premium names, or the registry quoted none for it), and "unconfirmed" means the registry lookup did not finish, so the price is not final for a name that may be premium. pricing_sources breaks this out per action.

Parametersnamesrequiredyears

search_domains

Search for available domain names

Find domain names from a free-text idea, brand or phrase; a phrase yields short combinations of its words. top_picks answers "how does my name look": the name as typed (when its extension isn't .com/.net/.org) and the name on .com, .net and .org, or on each extension in tlds, with its real status, taken and unknown included, as check_domain reports it. suggestions are up to `limit` ranked names a live check found available, never repeating a top pick, with per-year prices in USD, premium names included unless include_premium is false; match is exact_sld or variation, and hack is true for a domain hack such as danger.zone. unchecked_names lists names whose check came back unknown, left_out counts why other names checked aren't suggested, and with tlds, each extension says why it found nothing. Search is advisory: confirm the chosen name with check_domain before quoting it, and a purchase checks again. Read-only, no side effects.

Parameterstldslimitqueryrequiredyearsmax_priceinclude_premium

get_tld_requirements

Get an extension's prices and registration rules

Look up what OrbitFour charges and requires for domain extensions (TLDs): standard per-year registration, renewal, transfer and restore prices in USD plus the ICANN fee, the shortest and longest term, the fixed transfer term, whether WHOIS privacy is allowed, any eligibility restriction, whether browsers require HTTPS for its websites (https_required: .app, .dev), and JSON Schemas for what a registration must include (.us, for example, needs Nexus data on the registrant contact). Up to 10 extensions per call; read-only. These are standard prices: when premium_possible is true a particular name can cost more, so quote it with check_domain. An extension OrbitFour does not sell comes back as tld_not_found.

Parameterstldsrequired

check_transfer

Check whether domains can be transferred in

Ask each name's registry whether it can be transferred to OrbitFour now (not locked, no transfer or delete pending) and quote the full first-term transfer price in USD: the per-year price plus the ICANN fee for the registry's transfer term. Up to 5 names per call; read-only. transferable is true, false, or null (the registry could not be asked just now; not the same as locked), and reasons says why: invalid_name, unsupported_tld, already_here, not_registered (nobody holds it, so register it instead), locked, pending_transfer, pending_delete, premium_over_cap, price_unconfirmed, unknown. The price is what the transfer would cost if it goes ahead. Never send a transfer authorization code here: the transfer itself asks for it.
