Documentation

DomainKits MCP

Domain data server for AI assistants. DomainKits MCP connects Claude, GPT, Gemini, and other AI assistants to live domain registration, DNS, availability, trend, and market data through the Model Context Protocol.

This is the official MCP server for the DomainKits API, published and maintained by the DomainKits team. DomainKits is built and operated by ABTdomain, a domain intelligence platform, which also owns the GitHub organisation hosting this repository. The relationship is stated on domainkits.com/about.

MCP is the data layer. For domain industry workflows (naming consultation, competitive analysis, keyword intelligence, expired domain due diligence, and more), see DomainKits Skills, an open-source collection of workflow prompts that any AI assistant can use on top of this data.

Local install (npm)

Prefer a local stdio server? The same tools ship as an npm package:

Skills

DomainKits MCP serves raw data. DomainKits Skills are open-source workflow prompts that teach AI assistants how to use that data for domain industry tasks:

Domain Name Advisor -- naming consultation with availability checking
Domain Analyze -- comprehensive WHOIS, DNS, backlink, and market analysis
CMA Valuation -- comparative market analysis against current for-sale listings
Expired Domain Analysis -- due diligence for auction, backorder, and dropping domains
Keyword Intel -- keyword-level supply, demand, and concentration analysis
Keyword Trend Hunter -- spot trending keywords and find registration opportunities
Domain Generator -- creative domain name generation with validation
Plan B -- systematic alternatives when a target domain is taken

Skills work with any MCP client. Add them alongside this server and the AI assistant gains both raw data access and structured workflows.
