## Project history and usage

domain-check is a Rust command-line domain availability checker that combines RDAP-first lookups, WHOIS fallback, TLD expansion, pattern generation, JSON/CSV output, and an MCP server built on the same engine.

### Project history

The project appeared publicly in April 2025 and describes itself as a universal domain exploration engine. Its README emphasizes the combination of CLI, Rust library, and MCP server outputs, making it a newer tool shaped by both traditional domain search workflows and AI-agent integration.

### Adoption history

The README advertises installation through Homebrew, Cargo, and GitHub releases, while crates.io shows the CLI crate published shortly after the repository was created. By March 2026 the GitHub release stream had reached 1.0.2.

### How it is used

Typical usage checks a single domain, expands a base name across selected TLDs, applies startup or other presets, generates candidate names from patterns, or emits JSON and CSV for automation. The README also describes noninteractive flags for CI-style runs.

### Why package nerds care

domain-check is notable as a small modern Rust CLI that packages one engine three ways: terminal command, Rust library, and MCP server. That makes it a clean example of a package adapting an old internet task, domain availability checking, to current automation and AI-agent workflows.

### Timeline

- 2025: The public GitHub repository and crates.io package are created.
- 2026: The project reaches 1.0.0.
- 2026: GitHub releases show 1.0.2 published in March.

### Related projects

- Related projects and systems include RDAP, WHOIS, IANA TLD bootstrap data, crates.io, Homebrew, and MCP clients such as Claude, Codex, Gemini, Cursor, and VS Code Copilot as listed by the README.
