Domain Radar tools (4)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • check_brand_domains

    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.

  • check_domains

    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.

  • list_supported_tlds

    List all TLDs that this server can check via WHOIS, grouped by category.

  • suggest_and_check_domains

    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.

Install Domain Radar in Claude Code, Cursor or VS Code

Runs npx -y mcp-domain-radar on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add domain-radar -- npx -y mcp-domain-radar
Add to Cursor

What the publisher says

From the Domain Radar repository's README, as published. We do not edit it. Read it on GitHub

mcp-domain-radar

Works with Claude Code · Claude Desktop · Cursor · Codex CLI · any MCP-compatible client

MCP server that checks domain availability in real-time during brand naming.

Name your brand. Check the domain. All in one conversation.

Why?

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.

Quick Start

1. Install

npm install -g mcp-domain-radar

2. Connect to your AI coding tool

Claude Code

claude mcp add domain-radar -- mcp-domain-radar

Codex CLI

codex mcp add domain-radar -- npx mcp-domain-radar

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "domain-radar": {
      "command": "npx",
      "args": ["mcp-domain-radar"]
    }
  }
}

Claude Desktop

Add to claudedesktopconfig.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.

What You Get
