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, 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.

Tools

Search

Tool Description
nrds Newly registered domains by keyword, or browse a gTLD
aged Established domains with registration history by keyword, or browse a gTLD
expired Domains entering the deletion cycle by keyword, or browse a gTLD
deleted Just-dropped domains available for standard registration
active Live registered domains (~240M gTLD database)
market Domains carrying marketplace listing data by keyword, or browse a gTLD
ns_reverse Reverse lookup by nameserver
unregistered_ai Unregistered short .ai domains (3-letter, pattern-based)
domain_changes Domain change detection across 4M+ monitored domains (transfers, expirations, NS changes)
typosquat Typosquat scanner (dnstwist-style permutations) with live registration verification

Lookup

Tool Description
dns DNS records (A, AAAA, MX, NS, TXT, SOA)
whois WHOIS/RDAP registration data (registrar, dates, status, nameservers)
safety Google Safe Browsing status
available Single-domain availability with pricing
tld_check Keyword availability across TLDs

Stateful (require memory)

Tool Action Description
preferences get Check memory status and saved preferences
preferences set Save preferences (TLDs, budget, style, industry)
preferences delete Delete all stored data (GDPR Article 17)
monitor get Retrieve and check all monitored domains
monitor set Create a monitoring task (WHOIS, DNS, page changes)
monitor update Save check results for a monitor
monitor delete Remove a monitoring task
strategy get Retrieve saved strategies with run status
strategy set Store user-authored strategy text
strategy update Save strategy execution results
strategy delete Remove a strategy
usage Current tier, per-group usage, and remaining quota

Stateful data is server-side and cross-platform: preferences, monitors, and strategies persist across Claude, Gemini, Cursor, and any other MCP client under the same account. All data encrypted at rest (AES-256-GCM) in isolated per-user directories.

Gemini CLI

Edit ~/.gemini/settings.json:

{
  "mcpServers": {
    "domainkits": {
      "url": "https://api.domainkits.com/v1/mcp"
    }

Other MCP Clients

Endpoint: https://api.domainkits.com/v1/mcp

Optional header: X-API-Key: your-api-key-here

Local install (npm)

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

npx @domainkits/mcp

Set DOMAINKITS_API_KEY for higher limits; without it the server runs on the guest quota. Package: @domainkits/mcp.

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