Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-domain-radar Check if mybrand.com is available"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP server that checks domain availability in real-time during brand naming.
Name your brand. Check the domain. All in one conversation.
We've all been there:
You: "Suggest a name for my service"
AI: "How about NexFlow?"
You: Search nexflow.com... already taken
You: "Another one"
AI: "DataPulse?"
You: Search datapulse.com... also taken
You: "..."
(repeat 10 times)Install mcp-domain-radar once, and your AI checks domain availability the moment it thinks of a name. No more switching between browser and terminal.

1. Install
npm install -g mcp-domain-radar2. Connect to your AI coding tool
claude mcp add domain-radar -- mcp-domain-radarcodex mcp add domain-radar -- npx mcp-domain-radarAdd to .cursor/mcp.json:
{
"mcpServers": {
"domain-radar": {
"command": "npx",
"args": ["mcp-domain-radar"]
}
}
}Add to claude_desktop_config.json:
{
"mcpServers": {
"domain-radar": {
"command": "npx",
"args": ["mcp-domain-radar"]
}
}
}3. Install the brand-naming skill (optional, Claude Code only)
mkdir -p ~/.claude/skills/brand-naming
cp node_modules/mcp-domain-radar/.claude/skills/brand-naming/SKILL.md ~/.claude/skills/brand-naming/Or copy it manually from the GitHub repo.
4. Use it
With the skill installed, type /brand-naming in Claude Code to start a guided naming session.
Or just talk naturally:
"I'm building a task management app for developers.
Help me find a brand name with an available domain."Claude will automatically check domains as it brainstorms.

Check domain availability for a single brand name across many popular TLDs at once. Default TLDs: .com .io .dev .app .ai .co .so .me .xyz .tech .net .sh .run .cloud .to .gg .cc Supports 30+ TLDs including trending ones like .ai, .gg, .so, .lol, .wtf, .cool.
Inputs: name (required), tlds.
Check availability of specific domain names. Use this when you already have exact domain names to verify (e.g. "mybrand.com", "mybrand.ai"). Checks via DNS + WHOIS for accurate results.
Inputs: domains (required).
List all TLDs that this server can check via WHOIS, grouped by category.
Inputs: no named parameters.
Generate brand-name variations from keywords, then check domain availability for each. Creates variations using prefixes (get-, try-, my-…), suffixes (-hq, -lab, -flow…), compounds (keyword1+keyword2), and portmanteau blends. Great for brainstorming when obvious names are taken.
Inputs: keywords (required), tlds, max_variations.

Scored across 4 tools
Each tool has a distinct purpose: checking a brand across TLDs, checking specific domains, listing TLDs, and brainstorming variations. Minor potential confusion between check_brand_domains and check_domains, but descriptions clarify the difference.
Tool names follow a verb_noun pattern (check_, list_, suggest_and_check_). The compound verb in suggest_and_check_domains is a slight deviation, but overall consistent.
Four tools is appropriate for the domain checking and suggestion use case. Not too few or too many, each earns its place.
Covers core functionality: checking specific domains, checking a brand across TLDs, suggesting variations, and listing supported TLDs. Minor gaps like bulk brand checking or WHOIS details beyond availability, but sufficient for typical use.
