Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.
Add this to your MCP configuration file:
{
"mcpServers": {
"io-github-sonwr-domain-radar": {
"args": [
"-y",
"mcp-domain-radar"
],
"command": "npx"
}
}
}From the project's GitHub README.
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-radar
2. Connect to your AI coding tool
claude mcp add domain-radar -- mcp-domain-radar
codex mcp add domain-radar -- npx mcp-domain-radar
Add 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.
| Tool | What it does |
|---|---|
check_domains | Check exact domain names — "Is mybrand.com taken?" |
check_brand_domains | Check one name across 17+ TLDs at once — "Check nexflow across all popular TLDs" |
suggest_and_check_domains | Generate name variations from keywords & check all — "Brainstorm names from keywords: pulse, data, flow" |
list_supported_tlds | Show all TLDs this server supports |
| Category | TLDs |
|---|---|
| Classic | .com .net .org |
| Tech / Startup | .io .dev .app .co .tech .sh |
| Trending | .ai .gg .so .me .xyz .cc .to .run .cloud .tv |
| Creative | .lol .wtf .cool .world .studio .design |
| Commerce | .online .site .store |

You: Check if "nexflow" is available — try .com, .io, .ai, and .dev
AVAILABLE:
+ nexflow.dev
+ nexflow.ai
TAKEN:
- nexflow.com
- nexflow.io
--- 2 available / 2 taken / 0 unknown ---
You: I need a name for an AI code review tool.
Keywords: code, review, pulse, scan.
Find me names with available domains.
Generated 20 name variations from: code, review, pulse, scan
Checking .com .io .ai .dev .app .co for each
+ codepulse (compound) — available: .dev, .ai | taken: .com, .io
+ scanflow (suffix) — available: .ai, .dev, .app | taken: .com
+ getpulse (prefix) — available: .dev, .co | taken: .com, .io, .ai
+ revscan (blend) — available: .com, .io, .ai, .dev, .app, .co
- codelab (suffix) — all checked TLDs taken
TOP PICKS (have available domains):
revscan → revscan.com, revscan.io, revscan.ai, revscan.dev, revscan.app, revscan.co
codepulse → codepulse.dev, codepulse.ai
scanflow → scanflow.ai, scanflow.dev, scanflow.app
