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. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** domain-check - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - domain-check: normalized package name match | nixpkgs package indexes: pkgs/by-name/do/domain-check/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [whois](https://www.automicvault.com/pkg/brew/whois/) - Shares av.db curated category or tags: cli, dns, networking, whois. - [adns](https://www.automicvault.com/pkg/brew/adns/) - Shares av.db curated category or tags: cli, dns, networking. - [aliddns](https://www.automicvault.com/pkg/brew/aliddns/) - Shares av.db curated category or tags: cli, dns, networking. - [bind](https://www.automicvault.com/pkg/brew/bind/) - Shares av.db curated category or tags: cli, dns, networking. - [c-ares](https://www.automicvault.com/pkg/brew/c-ares/) - Shares av.db curated category or tags: cli, dns, networking. - [cdncheck](https://www.automicvault.com/pkg/brew/cdncheck/) - Shares av.db curated category or tags: cli, dns, networking. - [checkdmarc](https://www.automicvault.com/pkg/brew/checkdmarc/) - Shares av.db curated category or tags: cli, dns, networking. - [chinadns-c](https://www.automicvault.com/pkg/brew/chinadns-c/) - Shares av.db curated category or tags: cli, dns, networking. - [icann-rdap](https://www.automicvault.com/pkg/brew/icann-rdap/) - Local package facts share a topical domain.
