Domain Finding Tools
Point-in-time collection of open-source domain-finding tools, with a focus on AI agent skills, Claude Code skills, and MCP servers (compiled April 2026, may not be maintained)
About This Project
Domain-Finding-Tools is a curated index of open-source projects for finding, checking, and brainstorming domain names. The collection is organized into categories including AI agent skills, Claude Code skills, and MCP servers; CLI and library checkers; web-based naming tools; and domain portfolio management utilities. Entries reflect the state of each linked repository at the time of compilation in April 2026, and the index itself may not be actively maintained.
The index's primary focus is on tools that integrate domain lookups into AI assistant workflows. Listed entries include MCP servers that let Claude Desktop check availability across dozens of TLDs using DNS and WHOIS verification, Claude Code skills that generate brand-name candidates and run bulk availability checks, and a Rust-based checker that exposes RDAP lookups with WHOIS fallback through a CLI, library, and MCP server. Other entries use Go, Shell, and TypeScript for command-line scanners, pattern-based availability checkers, and self-hostable naming applications.
The collection is most useful to developers building agentic naming or domain-research pipelines, founders evaluating startup names, and developers who want to compare available open-source approaches to domain availability checking. The repository is released under CC0, while each linked project retains its own license.
