Description and use

**Summary**
s saidutt46/domain-check is a fast, universal domain‑availability checker that supports more than 1,200 top‑level domains, generates search patterns, and falls back from RDAP to WHOIS when needed. It ships as a command‑line tool, a Rust library, and a Model Context Protocol (MCP) server, enabling AI agents to query domain data through a standard protocol. With 276 ★ on GitHub, recent commits, and a clean Rust codebase, it is ready for serious pilot deployments.

**Value**
The project bridges the gap between AI assistants and real‑world internet resources by exposing domain‑availability data via a well‑defined MCP endpoint. This lets developers embed live domain checks into chat‑based tools, automated naming pipelines, or any AI‑driven workflow without writing custom scrapers or handling WHOIS quirks themselves. The same functionality is also available as a native Rust crate or a CLI, giving teams flexibility in how they integrate the service.

**Practical adoption path**

1. **Prototype** – Pull the Docker image or run the MCP server locally and test the API with a simple curl request or the provided CLI.
2. **Integrate** – Add the Rust crate to existing Rust services, or call the MCP endpoint from any language that can speak HTTP/JSON (e.g., Python, Node.js) to let AI agents query domain availability.
3. **Deploy** – Deploy the MCP server behind a load balancer or as a sidecar in a Kubernetes pod; the stateless design scales horizontally.
4. **Extend** – If custom TLDs or additional validation logic are needed, fork the Rust library and contribute back; the codebase is modular and well‑documented.

**Production readiness**

• **Activity & community** – Recent commits (last update 2026‑05‑14), 276 stars, and ongoing issue handling indicate an active maintainer.
• **Reliability** – Uses RDAP first, with WHOIS fallback, covering edge cases for domain registries.
• **Security** – No known licensing or vulnerability flags; the Rust ecosystem’s safety guarantees further reduce risk.
• **Scalability** – The MCP server is a lightweight HTTP service that can be horizontally scaled; the CLI and library have minimal runtime overhead.

Overall, the project shows strong signals for production use, especially for teams building AI‑driven naming or domain‑registration workflows.

Problem

saidutt46/domain-check helps connect AI assistants to real tools and data through a standard protocol.

Outcome

High for an OSS candidate: recent activity, adoption, and ecosystem signals are strong enough for a serious pilot.

Workflow

• connect AI agents to tools
• ship Model Context Protocol servers
• standardize integrations

Evidence

Fast, universal domain availability checker - 1,200+ TLDs, pattern generation, RDAP with WHOIS fallback. CLI + Rust library + MCP server for AI agents.
