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

}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.
