Whodis MCP Server

Overview

The Whodis MCP Server is a lightweight, standards‑compliant service that turns WHOIS lookups into an easily consumable tool for AI assistants and other external systems. By exposing a single MCP tool, it allows conversational agents to ask whether a domain name is likely unregistered and receive structured JSON results without having to write custom networking code or manage authentication tokens. This capability is particularly valuable for developers building product discovery, brand‑name generators, or domain‑sourcing workflows that need instant feedback on name viability.

At its core, the server leverages the library to query WHOIS servers for each supplied domain. It then interprets the responses, classifying them into and buckets. The service is intentionally simple: it accepts an array of domain strings, performs parallel lookups, and returns a clear JSON payload. This design keeps latency low while still handling the quirks of different top‑level domains, such as varying response formats or temporary rate limits. Developers can therefore integrate domain checks into larger AI pipelines—e.g., a Claude prompt that generates brand names and immediately verifies each candidate for purchase readiness.

Key features include:

• MCP‑ready tool definition that can be discovered by any MCP client, ensuring secure, authenticated communication.
• Structured logging and error handling that aid debugging when WHOIS servers are unreachable or return unexpected data.
• Environment‑driven configuration, allowing custom WHOIS server selection, timeout tuning, and logging verbosity without code changes.
• CLI support for quick manual testing or scripting outside of an AI workflow, which mirrors the MCP interface and produces identical JSON output.

Real‑world scenarios that benefit from this server are abundant. A startup founder could use an AI assistant to brainstorm domain names and immediately filter out those already taken, saving time on manual searches. An e‑commerce platform might integrate the tool to validate customer‑chosen store names before finalizing registration. Even marketing teams can employ it within automated content generation pipelines to ensure brand consistency across domains and subdomains.

The Whodis MCP Server stands out by providing a dedicated, protocol‑compliant domain availability service that is both developer‑friendly and AI‑centric. Its minimal footprint, clear API contract, and seamless integration with existing MCP tooling make it an ideal component for any project that needs reliable domain lookup capabilities embedded in conversational or automated workflows.
