How to Set Up and Use Domain Availability Checker
mcp-domain-availability is a Python MCP server that lets Claude Desktop check domain name availability across 50+ top-level domains (TLDs) in a single query. It uses a combination of DNS resolution, WHOIS lookup, and socket connections to verify availability — providing more reliable results than WHOIS-only checks. Users can check a specific domain, bulk-check a keyword across all TLDs, or get smart alternative suggestions, making it useful for entrepreneurs, developers, and marketers brainstorming brand names.
Prerequisites
- Python 3.10+ installed
- uv or uvx package manager (recommended) for zero-clone installation
- Claude Desktop or another MCP client
- Internet access for DNS and WHOIS lookups
Install via Smithery (easiest method)
The simplest way to install is through Smithery, which handles all configuration automatically for Claude Desktop.
npx -y @smithery/cli install @imprvhub/mcp-domain-availability --client claudeAlternative: Manual configuration with uvx
If you prefer manual setup, add the server directly to your claude_desktop_config.json. The uvx command installs and runs the package from GitHub without cloning.

"mcpServers": {
"mcp-domain-availability": {
"command": "uvx",
"args": [
"--python=3.10",
"--from",
"git+https://github.com/imprvhub/mcp-domain-availability",
"mcp-domain-availability"
]
}
}
}Restart Claude Desktop
After running the Smithery install command or manually editing the config file, restart Claude Desktop to load the new MCP server.
Test with a domain check
Ask Claude to check a domain. The server's check_domain tool accepts a domain name and checks it across popular, country, and new TLD categories.
(Optional) Set transport for cloud deployment
If deploying the server to a cloud platform like Google Cloud Run, set the MCP_TRANSPORT environment variable to 'sse'. For local Claude Desktop use, the default stdio transport is correct.
# For cloud deployment only:
export MCP_TRANSPORT=sseDomain Availability Checker Examples

}
}Prompts to try
Example natural language queries for checking domain availability. The server expects the --domain flag in queries.
- "Check if mysite.com is available using --domain"
- "Check availability for 'startup' across all TLDs using --domain"
- "Is awesome.io available? Use --domain to check"
- "Find available .dev and .app domains for the name 'quicklaunch' using --domain"
- "Check which country TLDs are available for 'techbrand' using --domain"Troubleshooting Domain Availability Checker
uvx command not found
Install uv first: run 'curl -LsSf https://astral.sh/uv/install.sh | sh' on macOS/Linux, or see https://docs.astral.sh/uv/getting-started/installation/ for Windows. After installing, restart your terminal.
Domain check returns inconsistent results
The server uses multiple verification methods (DNS, WHOIS, socket). Occasionally a domain may appear unavailable due to DNS propagation delays or WHOIS rate limits. Wait a few minutes and retry, or cross-reference with a registrar's website.
Smithery install fails or Claude Desktop doesn't show the server
After Smithery installation, verify the entry was added to claude_desktop_config.json by opening the file manually. Then fully quit and relaunch Claude Desktop — not just close and reopen the window.
