A side-by-side look at the MCP Server and NameWheel MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose MCP Server for communication work as a local process; choose NameWheel for communication. You can also run both side by side in one mcpServers block.

get_balanceCurrent account balance. Ordering a number needs a funded balance; there is no free tier.list_countriesEvery country the numbers can come from, with its id and operators. Use the id in order_number.list_servicesServices available in a country, best match first. Order the code of the site you are registering with: a number bought for one service does not receive another service's SMS. Search by site name or domain, both work. The codes are arbitrary, so look them up instead of guessing: uk is Airbnb, not the United Kingdom. deliveredPercent is null when the pair has no statistics yet, which is the common case; then judge the pair by how many numbers are online. When the site is not in the catalogue at all, order notInList (ot), which receives SMS from any sender that is not in the list.order_numberOrder a private number for one service in one country. The number is held for 20 minutes and belongs to this activation alone. Money is held now and charged when the code arrives. The service code has to be the one for the site you are registering with, otherwise its SMS goes to a different pool and never reaches you.wait_for_codeWait for the verification code on an ordered number. Polls on its own and returns the code itself, already parsed out of the SMS. Trigger the SMS on the target service first.finish_activationClose an activation after the code was used. Do this on every success: a forgotten activation holds money until it expires.cancel_activationCancel an activation when no code arrived; the money returns to the balance in full. Can be called right after ordering. If the API answers that it is too early, wait a couple of minutes and repeat.request_another_smsAsk for one more code on the same number, for a password reset or a re-send. Works only after a first code has already arrived; before that the API refuses it.totp_codeCompute the authenticator code for an account whose second factor was set up with a shared secret. Runs locally by RFC 6238: the secret never leaves this machine.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

spin_wheelPick one or more winners at random from a list of names or options, and show the wheel spinning to the result in the chat. Use it whenever the person wants something chosen at random: a student to answer, who goes first, where to eat, a raffle winner among friends. Works without an account. The pick is fair (a cryptographic random number generator), but it is not a certified record; when other people need to be able to check the result later, use certified_draw instead.make_teamsSplit a list of names into random teams or groups of even size, and show them as cards in the chat. Use it for class groups, project teams, game sides, rotations. Give either how many teams or how many people per team. Works without an account.open_wheel_linkMake a namewheel.org link that opens the full NameWheel wheel with these names already loaded, for spinning on a projector, a stream or a shared screen with sound, modes and themes. Works without an account. Commas inside a name become spaces in the link.certified_drawRun a TrueSpin certified draw on NameWheel: the winner is sealed by NameWheel's server before it is revealed, randomness from this connection is added, and the result is published on a permanent public proof page (namewheel.org/v/CODE) that anyone can check, with a button that recomputes the draw. Use it when the result must be provable to other people: a class prize, a team decision, a draw announced to a group. IMPORTANT: the title, every entry and the winner become public on the proof page, so only use names the person is happy to publish, and tell them so. Needs a connected NameWheel account (free). To draw against a list locked earlier with freeze_list, pass frozen_code instead of entries.freeze_listLock a list of entries in public before a draw, at namewheel.org/f/CODE, with a fingerprint and the exact time. Nobody can add or remove a name after that, and when certified_draw later uses this list (frozen_code), the frozen page links to the result. Use it when entries close before the draw happens. The title and every entry are public. Needs a connected NameWheel account (free).verify_drawCheck whether a NameWheel certified draw is genuine, from its code or its namewheel.org/v/ link: recomputes the winner from the published secret, the added randomness and the entries, checks the commitment made before the spin, and checks NameWheel's Ed25519 signature on the record. Also says how many draws the host ran on this exact list. Use it when someone asks whether a draw or a giveaway result was real. Works without an account.my_drawsList this account's recent NameWheel certified draws (or frozen lists) with their winners and proof links, newest first. Needs a connected NameWheel account.check_planSay what this NameWheel connection can do: without an account (spins, teams, wheel links, checking draws) or with a connected account (certified draws, frozen lists, the account's draws), and how many certified draws are left today. Use it when the person asks about limits, their account, or why a request was refused.
