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.

Examples

Search and discovery

"Find domains with 'solar' registered in the last 7 days"
"What has been registered in the last few hours with 'agent' in the name?"
"What .com domains are expiring this week?"
"Show me trending keywords in .com registrations"
"What short domains changed nameservers this week?"

Lookup

"Check DNS and WHOIS for example.com"
"Is mybrand.ai available? What does it cost?"
"What domains are on ns1.example.com?"

Trends

"What are the hottest keywords in domain registrations right now?"
"Compare .com vs .net registration trends over 90 days"

Monitoring (requires memory)

"Monitor example.com for WHOIS and DNS changes"
"Save a strategy: find dropping 4-letter .com domains daily"
