# Fast CLI to bulk-check domains via RDAP & MCP

**[Product Hunt](https://daily.dev/sources/ph)** · 1 min read · 0 upvotes · 0 comments

## Summary

tldx is a free, open-source CLI tool written in Go for bulk-checking domain availability using RDAP (replacing legacy WHOIS). It supports keyword mixing, prefixes/suffixes, and regex patterns, with output to stdout, JSON, or CSV. It also includes an MCP server so AI agents like Claude can brainstorm and verify domain names automatically. Install via Homebrew.
