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 Lyalpha GmbH, with domain data and infrastructure provided by ABTdomain, our domain intelligence and data aggregation platform. This repository is hosted under the ABTdomain GitHub organisation. Learn more about the relationship at domainkits.com/about.

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

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:

• Brand Protection -- scan typosquats and lookalike registrations around a brand, evaluated per domain on registration facts
• Domain Analyze -- registration, DNS, website, safety, backlink, cross-TLD and market evidence for one domain
• Domain CMA Valuation -- comparative market analysis against current for-sale listings
• Domain Generator -- creative domain name generation with validation
• Domain Market Beat -- time-bounded domain market briefing with source tiers and explicit inference limits
• Domain Name Advisor -- naming consultation with availability checking
• Keyword Intel -- keyword-level supply, demand, and concentration analysis
• Keyword Trend Hunter -- spot trending keywords and validate them against new registration cohorts

Skills work with any agent that supports the Agent Skills open standard. Add them alongside this server and the AI assistant gains both raw data access and structured workflows.

Access

Works without an API key on a guest quota. A free account raises it; paid tiers raise it further and unlock the full filter set and deeper paging. Current per-tier limits are listed at domainkits.com/pricing; the usage tool reports the live quota for your own account.
