Fast CLI to bulk-check domains via RDAP & MCP
tldx is a high-performance CLI tool designed for domain enthusiasts, developers, and cybersecurity professionals who need to quickly check domain availability in bulk. Built in Go, tldx leverages RDAP and MCP protocols to provide fast, reliable domain data without the typical rate limits or outdated whois parsing issues. Its concurrent processing ensures rapid results, making it ideal for large-scale domain research or bulk generation tasks. Users can mix keywords, prefixes, suffixes, or regex patterns to generate domain lists, then stream the availability data directly to stdout, JSON, or CSV formats. Additionally, tldx includes an MCP server that enables AI agents like Claude to brainstorm and verify domains automatically, streamlining complex workflows. Its open-source nature and easy installation via Homebrew make it accessible for developers who want a customizable, powerful tool for domain management and research.
