# domain-check Universal domain exploration engine: fast domain availability checks across the internet — as a CLI, Rust library, and MCP server for AI agents.

No config needed. 32 hardcoded TLDs work offline as fallback. - **Dual-protocol engine** — RDAP-first with automatic WHOIS fallback. IANA server discovery covers ~189 ccTLDs that lack RDAP (`.es`, `.co`, `.eu`, `.jp`). - **Fast** — up to 100 concurrent checks, streaming results as they complete. 2.7 MB release binary. - **Domain generation** — pattern expansion (`\w`=letter, `\d`=digit, `?`=either), prefix/suffix permutations, and `--dry-run` to preview before checking. - **11 curated presets** — `startup`, `tech`, `creative`, `finance`, `ecommerce`, and more. Or define your own in config. - **Rich output** — grouped pretty display, JSON, CSV. Registrar info, creation/expiration dates, and status codes with `--info`. - **CI and automation friendly** — `--json`/`--csv` to stdout, `--yes` to skip prompts, `--force` for large runs, automatic non-TTY detection. - **Configurable** — TOML config files, `DC_*` environment variables, custom presets, and clear precedence rules. - **Agent-native** — MCP server exposes all tools to AI coding agents (Claude, Codex, Gemini, Cursor, VS Code Copilot, and any MCP client). - **CLI + library + MCP** — same engine powers the CLI, [`domain-check-lib`](https://crates.io/crates/domain-check-lib) (Rust library), and [`domain-check-mcp`](https://crates.io/crates/domain-check-mcp) (MCP server). ## Installation | Method | Command | Notes | |---|---|---| | Homebrew (macOS) | `brew install domain-check` | Easiest install for macOS users | | Cargo (CLI) | `cargo install domain-check` | Works on all Rust-supported platforms | | Cargo (MCP) | `cargo install domain-check-mcp` | MCP server for AI agents | | GitHub Releases | [Download binaries](https://github.com/saidutt46/domain-check/releases) | CLI + MCP binaries for macOS, Linux, Windows | ## Quick Start ```bash # Check a single domain domain-check example.com # Expand a base name across TLDs domain-check mystartup -t com,org,io,dev # Use a curated preset domain-check myapp --preset startup --pretty # Generate names with a pattern (preview only) domain-check...
