Nothing to run from here
DomChecker is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Domain availability, WHOIS and DNS for any TLD (.ru, .рф, .com…), straight from registries.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http domchecker-mcp https://domchecker.ru/mcp
# 2 — ask your agent for something these tools do

DomChecker costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http domchecker-mcp https://domchecker.ru/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
9 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface

Свободен домен или занят — по-настоящему, запросом в реестр, а не по словарю. Годится любая зона: .ru, .рф, .com, .io, .co.uk и остальные. Имя можно давать как угодно — «example.com», «https://example.com/page», «пример.рф»: лишнее отбрасывается, кириллица переводится в punycode. Без зоны (просто «пример») проверяется .ru и заодно популярные зоны с тем же именем.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | домен, например example.com или пример.рф |
То же самое сразу для списка, до 50 имён за вызов. Зовите его, когда доменов больше одного: список проверяется одним заходом и заметно быстрее, чем по одному. Что не поместилось — названо в ответе, а не отброшено молча.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domains | array | yes | список доменов, до 50 |
| only_available | boolean | no | оставить в ответе только свободные |
Достаёт доменные имена из произвольного текста и проверяет каждое. Если зона не названа (просто слово) — проверяет это имя в популярных зонах: .ru, .com, .net, .org и прочих. Имена НЕ придумывает: проверяет ровно то, что названо. Варианты придумывайте сами и присылайте списком в check_domains.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | yes | домен, несколько доменов через пробел или имя без зоны |
Запись реестра об одном домене: регистратор, дата регистрации и возраст, срок регистрации (у .ru/.рф/.su — «оплачен до», у остальных — срок в реестре, который реестр сам сдвигает автопродлением), когда освободится (.ru/.рф/.su — поле free-date), серверы имён, статусы, владелец — только если реестр его раскрывает (частные лица в .ru и почти все .com скрыты). Данные берутся у реестра по RDAP или WHO
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | домен, например example.ru или пример.рф |
A, AAAA, CNAME, MX, NS, TXT, SOA, CAA одного имени (домена или поддомена) и есть ли SPF и DMARC. Ответ публичного резолвера (Cloudflare, запасной Google) с его кэшем: свежая правка зоны видна через TTL. NXDOMAIN — имени в DNS нет.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | домен или поддомен, например mail.example.ru |
Факты для оценки незнакомого сайта: возраст и срок регистрации домена, скрыт ли владелец, регистратор, действует ли HTTPS-сертификат, чья сеть хостинга, настроены ли SPF и DMARC. У каждого факта тон obychno или vnimanie и пояснение. Вердикта «мошенник/честный» сервер не выносит и на вирусы не проверяет — не делайте из этих фактов окончательного вывода.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | адрес сайта, например shop-example.ru или https://www.shop.ru/ |
Один домен подробно, документом со ссылкой — для цитирования в ответе.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | домен |
ОБРАТНАЯ СВЯЗЬ О САМОМ ЭТОМ СЕРВЕРЕ, а не о доменах. Зовите, когда инструмент повёл себя не так, как обещает описание; когда не хватило параметра или поля в ответе; когда отказ пришёл без внятной причины; когда описание непонятно. Пишите КОНКРЕТНО: имя инструмента, что звали, что ждали, что получили — читать это будет человек, и по «не работает» он не поймёт, что чинить. Повторная жалоба о том же
| Parameter | Type | Required | Notes |
|---|---|---|---|
| title | string | yes | суть одной фразой, от 10 знаков |
| body | string | no | что звали, с какими аргументами, что ждали, что пришло |
| kind | string | no | проблема — работает не так; доработка — не хватает; вопрос — неясно из описания |
| tool | string | no | имя инструмента; пусто — о сервере целиком |
Что уже сообщено об этом сервере и в каком это состоянии. ЗОВИТЕ ПЕРЕД feedback_add, если не уверены, что о таком ещё не писали: увидите и чужие замечания, и ответ человека на них. По умолчанию показываются живые. Менять статус и удалять записи отсюда нельзя — приёмку ведёт человек в панели.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| вид | string | no | по умолчанию живые |
| tool | string | no | только про этот инструмент |
| q | string | no | слово в заголовке или тексте |

ATool-list grade · score 93 / 100
Release 2.8.0 · scanned 28 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

Score vectorthreat 100 → client 93
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
flow-1
Untrusted input can drive an external action even though no sensitive source is exposed.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish DomChecker can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
