How to Set Up and Use Domain Availability Checker

The Domain Availability Checker MCP server enables Claude Desktop to check domain name availability across 50+ top-level domains in a single request. It uses multi-method verification combining DNS resolution, WHOIS lookups, and socket connections to give accurate availability results, supports bulk parallel checking of up to 20 domains simultaneously, and groups results by TLD category. Domain investors, startup founders, and developers picking project names will find this a fast way to research domain options directly in Claude.

Prerequisites

  • Python 3.10 or higher
  • uv package manager installed (pip install uv or see https://docs.astral.sh/uv/)
  • Internet access for DNS and WHOIS queries
  • Claude Desktop or another MCP-compatible client
1

Install via Smithery (recommended)

The quickest installation method is via Smithery CLI, which handles configuration automatically.

npx -y @smithery/cli install @imprvhub/mcp-domain-availability --client claude
2

Or configure manually in Claude Desktop

Alternatively, add the server directly to your Claude Desktop configuration file. The server is installed on demand via uvx โ€” no separate pip install needed.

3

Edit claude_desktop_config.json

Open your Claude Desktop config file and add the domain availability server entry. The uvx command fetches and runs the package directly from GitHub.

{
  "mcpServers": {
    "mcp-domain-availability": {
      "command": "uvx",
      "args": [
        "--python=3.10",
        "--from",
        "git+https://github.com/imprvhub/mcp-domain-availability",
        "mcp-domain-availability"
      ]
    }
  }
}
4

Restart Claude Desktop

Quit and relaunch Claude Desktop to apply the configuration. The domain checker tool will be available on next startup.

5

Test with a domain check

Ask Claude to check domain availability to confirm the server is working. Use the --domain flag syntax as shown in the tool documentation.

Domain Availability Checker Examples

Client configuration

Manual configuration for Claude Desktop using uvx to run the domain availability checker 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"
      ]
    }
  }
}

Prompts to try

Ask Claude to check domain availability for names and TLDs you care about.

- "Check if mystartup.com is available"
- "Check availability for 'coolapp' across all TLDs"
- "Is myproject.io available?"
- "Check mysite.com, mysite.net, and mysite.org and tell me which are free"
- "Find available domains for the name 'launchpad' across popular TLDs"

Troubleshooting Domain Availability Checker

uvx command not found when Claude Desktop tries to start the server

Install uv: run pip install uv or follow the instructions at https://docs.astral.sh/uv/getting-started/installation/. Ensure uv/uvx is in the PATH accessible to Claude Desktop.

Domain check returns inconsistent results (shows available when it is taken)

The server uses DNS, WHOIS, and socket checks together. Some WHOIS servers rate-limit requests. Wait a moment and retry. For critical decisions, always verify through a registrar.

Python version error during uvx installation

The --python=3.10 flag requires Python 3.10+ to be available. Install it from python.org and ensure uv can find it. You can also try --python=3.11 or --python=3.12.
