domain-search-mcp and mcp-domain-availability
These two tools are competitors, as both implement a Model Context Protocol (MCP) server designed to provide domain availability checking within AI chat platforms like Claude and ChatGPT.
About domain-search-mcp
dorukardahan/domain-search-mcp
Zero-config domain availability MCP for Claude & ChatGPT. AI suggestions, premium/auction detection via GoDaddy, RDAP/WHOIS fallback. Stdio + HTTP.
Implements a tiered availability lookup chain (RDAP → GoDaddy → WHOIS) with circuit breaker protection to balance speed and resilience, while separating zero-config availability checks from optional backend-managed pricing APIs. Includes AI-powered domain suggestion via a fine-tuned Qwen 7B-DPO model, bulk validation for up to 100 names, social handle verification, and both stdio and HTTP/SSE transports with OpenAPI specs for ChatGPT Actions and REST clients. Built-in Redis support enables distributed caching across multiple MCP instances, with observability via Prometheus metrics and health endpoints.
About mcp-domain-availability
imprvhub/mcp-domain-availability
A Model Context Protocol (MCP) server that enables Claude Desktop to check domain availability across 50+ TLDs. Features DNS/WHOIS verification, bulk checking, and smart suggestions. Zero-clone installation via uvx.
Implements dual verification through DNS resolution and WHOIS lookups with automatic fallback to socket-based checking, ensuring accuracy across varied domain registry configurations. Supports both stdio transport (Claude Desktop) and SSE transport for cloud deployments like Google Cloud Run, with parallel processing for efficient bulk domain queries. Exposes tools via MCP's standard tool interface, enabling Claude to invoke domain checks as natural language requests without requiring users to format specific commands.
