Domain search MCP: .com names verified available live via Verisign RDAP - not AI guess lists

VerifiedStreamable HTTPWeb executableWeb Search & ScrapingBusiness & Commerce

Overview

AI-generated overview

Remote MCP server that generates brandable .com names and returns only domains verified available via the Verisign RDAP registry.

What you can do
  • Generate brandable .com name ideas for a business idea and get back only names currently available to register
  • Enumerate available domains by pattern (starts with, ends with, contains a keyword) across TLDs
  • Check a single domain's availability and pull a due-diligence report: registration age, expiry, status, backlinks and authority, toxic-linker audit, website history and trademark search links
When to use it
Useful when naming a business, product or startup and you want candidate domains that can actually be registered, rather than AI-suggested names that were taken years ago. Also handy for a quick due-diligence pass before buying a specific domain.
Requirements
A remote HTTP endpoint; no install and no API key. Works with any MCP client that supports remote HTTP servers, such as Claude Code, Claude Desktop, Cursor, VS Code or Windsurf. Network access to the provider's endpoint is required.
Before you install
Availability answers can be up to 10 minutes old, so confirm at a registrar before relying on a name. The due-diligence report includes an optional blacklist check only when configured. Queries, including your business idea and keywords, are sent to a third-party service; review its privacy policy. The server does not register or buy domains.

Installation

In SourceWeft

  1. Open Domain Search King Mcp 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/io.github.johnsmalls22-rgb%2Fdomain-search-king-mcp/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

Other MCP clients

Add this to your client's mcpServers config.

Domain Search King — MCP Server for Available Domain Name Search

[johnsmalls22-rgb/domain-search-king-mcp MCP server]

Find domain names that are actually available to register — verified live against the Verisign RDAP registry, not AI guesses.

Remote MCP (Model Context Protocol) server for Claude, Claude Code, Cursor, VS Code, Windsurf, and any MCP-compatible AI agent. Ask your AI for business name ideas and get back only .com domains that are available right now.

  • Endpoint: https://domainsearchking.com/api/mcp (remote HTTP, JSON-RPC 2.0 — no install, no API key)
  • Product page + one-click install: https://domainsearchking.com/mcp

Why this exists: AI models hallucinate domain availability

LLMs confidently suggest domain names that were registered decades ago. Our AI Domain Hallucination Index found up to 92% of AI-suggested domains are already taken.

Real examples — names AI models routinely call "available":

Domain AI suggestedReality (RDAP registry record)
dailygrind.comRegistered since 1995
morningritual.comRegistered since 2004

Domain Search King checks every name against the live registry before your agent ever sees it. Verified-available examples returned at time of writing: lunaroast.com, brewotic.com, duskern.com, mochanox.com.

Tools

Install

Claude Code (CLI):

bash
claude mcp add --transport http domain-search-king https://domainsearchking.com/api/mcp

Claude Desktop / Cursor / other MCP clients — add to your MCP config:

json
{  "mcpServers": {    "domain-search-king": { "url": "https://domainsearchking.com/api/mcp" }  }}

Claude Skill (ClawHub): clawhub install dsk-available-domains — https://clawhub.ai/johnsmalls22-rgb/skills/dsk-available-domains

Per-client setup tabs (VS Code, Windsurf, and more) + an in-page inspector: https://domainsearchking.com/mcp

How it works

Every candidate name is checked live against the authoritative Verisign RDAP registry at query time. No cached lists, no WHOIS scraping, no guessing. If the tool returns a name, it was available at the moment you asked.

FAQ

Is it free? Yes — the MCP server and the site tools are free to use.

Why only names that are available? Because a name idea you can't register is worthless. Other generators give ideas; Domain Search King gives you names you can actually buy right now.

What's RDAP? The registry's official successor to WHOIS — structured, authoritative registration data straight from Verisign. It's how we verify availability live instead of guessing.

Tools

find_available_domains

Find available .com names

Generate brandable .com domain names for a business idea and return ONLY the ones that are currently AVAILABLE to register (checked against the Verisign RDAP registry through a caching proxy; an available answer can be up to 10 minutes old). Give a keyword and, ideally, a short description of the business for better names.

Parameterscountkeywordrequireddescription

find_available_domains_by_pattern

List available domains by keyword pattern

Exhaustively enumerate EVERY available domain matching a keyword PATTERN, across TLDs — the thing most domain tools/MCPs can't do. Give a keyword (or several) and a position: 'starts' (keyword+word, e.g. Bearoak), 'ends' (word+keyword, e.g. Oakbear), 'contains' (keyword inside a longer invented word, e.g. Oakbearen), or 'all'. Every candidate is checked against the registry (cached answers up to 10 minutes old); only AVAILABLE domains are returned, grouped by TLD. Checks .com and .net by default.

Parameterstldslimitkeywordrequiredposition

Domain due-diligence report

Full due-diligence report for one domain: registration age/expiry/status (live RDAP), backlinks & authority from our own Common Crawl link graph, toxic-linker audit, website history (Wayback), trademark search links, and optional blacklist when configured. Use before buying a domain. No composite appraisal score — flags + per-section detail only.

100% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
