Brave Search MCP Server: web results, images, videos, rich results, AI summaries, and more.
Nothing to run from here
GoMain 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 and prices from 40+ registrars, name checks, DNS setup, and a domain broker
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http gomain-mcp https://gomain.hottub.workers.dev/mcp
# 2 — ask your agent for something these tools do
# check_availability, compare_prices, suggest_names and 12 more
GoMain 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 gomain-mcp https://gomain.hottub.workers.dev/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
15 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
What the model actually sees. Descriptions are diffed on every release — see version history.
Check whether domain names are registered, asking each TLD's registry directly (RDAP). Returns registered, available, likely_available (no registry lookup service, but no DNS records either) or unknown, plus the registrar and dates for taken names and the cheapest prices for open ones. Up to 20 names per call. A lookup is not a reservation: names can be taken at any moment, and premium or reserved
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domains | array | yes | Domain names, like "example.com" or "münchen.de" |
Every tracked registrar's price for one TLD, in US dollars per year, refreshed daily from 40+ registrars. Sorted by 3-year cost (first year plus two renewals) by default, because a cheap first year often hides an expensive renewal. Each offer links to where to buy.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| limit | integer | no | — |
| sort | string | no | — |
| tld | string | yes | A TLD ("ai", ".co.uk") or a domain to take it from ("example.ai") |
Turn a few keywords into domain name candidates (the words joined, with common prefixes and suffixes, across several TLDs), check each with its registry, and return the available ones with prices. For your own name ideas, use check_availability.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| keywords | string | yes | A few words about the project, like "coffee map" |
| limit | integer | no | How many candidates to check |
| tlds | array | no | TLDs to try, first one preferred. Default: com, ai, io, dev, app, co |
Who runs a TLD, its type (generic, country-code, ...), when it was delegated, its registry's website and lookup servers (from IANA), and its cheapest first-year, renewal and 3-year prices.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tld | string | yes | A TLD ("ai", ".co.uk") or a domain to take it from ("example.ai") |
Every recorded price change for one TLD, oldest first, from GoMain's daily archive. A registrar's first entry is its price when the archive began (or when it started selling the TLD); later entries are changes. Prices are per year, in US dollars unless currency says otherwise.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| registrar | string | no | Only this registrar's changes, by id ("porkbun") |
| tld | string | yes | A TLD ("ai", ".co.uk") or a domain to take it from ("example.ai") |
Is a project name usable everywhere it'll be needed? Checks the domain across TLDs (with prices), GitHub, npm, PyPI and crates.io, and gives links for trademark and social-handle checks that can't be automated.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | The name, like "tidepool" |
| tlds | array | no | TLDs to check. Default: com, ai, io, dev, app, co |
The exact DNS records to add so a domain serves a website (Vercel, Netlify, GitHub Pages, Cloudflare Pages) and receives email (Google Workspace, Microsoft 365, Fastmail, Zoho, Proton), plus a starting DMARC policy. Checks live DNS to show which records are already in place and warns about clashes such as two SPF records. Values a provider generates per account are marked as such.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| account | string | no | GitHub user, Netlify site or Cloudflare Pages project name, when the website host needs one |
| domain | string | yes | — |
| string | no | — | |
| website | string | no | — |
A rough value range for a domain, from its length, how easy it is to say, its TLD, its age and how many popular TLDs have the same name registered. Use it to set a realistic budget before trying to buy a taken name. Not a comparable-sales appraisal.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | — |
For a domain someone already owns: whether it's listed for sale and where (with the asking price when the sale page shows one), when it could drop, its estimated value, the realistic chance of buying it, the options in order (buy now, make an offer, backorder, have GoMain broker it, watch it) and available alternatives with prices.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | — |
Ask GoMain's brokerage to acquire a domain someone else owns. GoMain researches it, approaches the owner without naming the buyer, negotiates within the budget (which the owner never sees), and closes through Escrow.com. Confirm the buyer's email and budget with the user before calling. Returns a deal id and status key for broker_status.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | — |
| string | yes | The buyer's email, for progress reports and the escrow invitation | |
| max_budget | integer | yes | The most the buyer will pay, in US dollars |
| notes | string | no | Anything the broker should know, like a deadline |
Search domains their owners have listed for sale with GoMain (each owner proved control of the name). Returns asking prices where set; make_offer buys or negotiates.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| keywords | string | no | Words the name should contain; empty lists everything |
| max_price | integer | no | — |
Offer to buy a domain listed with GoMain. Offers at or above the asking price buy it outright; lower offers are negotiated automatically with a counter-offer, for up to three rounds, then the seller decides. An accepted offer opens an Escrow.com transaction, so the money is only released once the domain arrives. Confirm the amount and email with the user before calling; to answer a counter-offer,
| Parameter | Type | Required | Notes |
|---|---|---|---|
| amount | integer | yes | US dollars |
| deal_id | string | no | — |
| domain | string | yes | — |
| string | yes | The buyer's email | |
| status_key | string | no | — |
List a domain the user owns for sale. The first call returns a DNS TXT record that proves ownership; once it's added, calling again with the same domain and email activates the listing. asking_price is shown to buyers; floor_price, the lowest offer accepted automatically, never is. Sales close through Escrow.com.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asking_price | integer | no | — |
| domain | string | yes | — |
| string | yes | The owner's email | |
| floor_price | integer | no | — |
| listing_key | string | no | Needed to change an active listing |
| withdraw | boolean | no | — |
GoMain checks a domain daily and emails when it drops (or is about to), changes hands, or is listed for sale. Returns a watch id and status key for broker_status.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | — |
| string | yes | — |
The status and history of a brokerage deal (id d_…) or a watch (id w_…), given the id and status key returned when it was created.

ATool-list grade · score 93 / 100
Release 1.0.0 · scanned 23 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 = 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.

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 GoMain 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.
