DomainKits: Domain Intelligence for Claude

DomainKits turns domain data into answers. It does the search, retrieval, and correlation across registration pipelines (new / expired / deleted / aged), nameserver indexes, keyword registration trends, WHOIS/DNS, backlink and market datasets. Claude does the analysis.

Three jobs: finding domain opportunities, protecting your brand, and watching new registrations for threats.

Who it's for

Domain investors: trends, discovery, valuation

• "What keywords are spiking in new registrations this week, and which spikes are real demand vs. bulk speculation?"
• "Find expired .com domains about fitness with a clean backlink profile" → /domainkits:hunt
• "Is brightpay.com worth the $3k ask? Full due diligence" → /domainkits:analyze brightpay.com
• "Which naming prefixes are trending, and where is the .com still open?"

Brand protection: what is getting registered around your name

• "Any new registrations containing 'acme' in the last 10 days?" → /domainkits:watch acme
• "The same prefix just appeared across 30+ TLDs. Is a registration pattern forming around our name?"
• "Where is 'acme' registered across TLDs, and which are still open to defend?"
• "Watch acme-related domains for WHOIS/DNS changes" (account feature)

Security teams: NRDs as the signal, nameserver correlation as the pivot

• "New domains resembling 'ourbank' registered this week?" → /domainkits:watch ourbank
• "This lookalike is an active phishing site, what else is hosted on its nameservers?" (ns_reverse maps the campaign)
• "Any emerging keyword spikes with single-registrar, single-nameserver concentration?" (coordinated-operation signal)
• "Full WHOIS/DNS workup on this suspicious domain" → /domainkits:analyze

In Claude Code, results compose with everything else Claude can do: write triage reports and shortlists to files, run bulk pipelines over your domain lists, schedule recurring sweeps, cross-check with web research.

Commands

Command	For	What it does
/domainkits:hunt [thesis]	Investors	Opportunity discovery: expired, deleted, aged, trending, or unregistered names matching your thesis
/domainkits:watch <brand/keyword>	Brand & security	Sweep new registrations and TLDs for a term; triage into benign / brand conflict / suspicious; pivot suspects through their nameservers
/domainkits:analyze <domain>	Everyone	Full workup on one domain: registration, DNS, backlinks, value, market signals

No command needed for ad-hoc questions. The bundled skills load automatically when a task involves domains.

Capabilities

• Discover: newly registered, expired, deleted, aged, and active domains; reverse-nameserver mapping; unregistered short domains
• Evaluate: backlink profiles, keyword volume/CPC, aftermarket prices
• Act: availability checks with registrar pricing, bulk checks, TLD-wide keyword availability
• Trends: keyword registration trends with quality metrics (.com share, sale-platform nameserver share, registrar/NS concentration), TLD ranking and historical trends
• Track: monitors (WHOIS/DNS/page changes) and saved strategies on your DomainKits account

Bundled workflow skills

The plugin ships eight open-source workflow skills that auto-activate on matching tasks:

Skill	What it does
brand-protection	Scan typosquats and lookalike registrations around a brand, evaluate each domain individually on registration facts, offer monitoring
domain-analyze	Evidence-based picture of one domain: registration, DNS, backlinks, cross-TLD footprint, market context
domain-cma-valuation	Comparative Market Analysis against verified for-sale substitutes in the same keyword market
domain-generator	Creative brandable names from a keyword, concept, or taken domain, verified available at check time
domain-name-advisor	Naming consultation across registration, drop-catch, backorder, and aftermarket paths
keyword-intel	Evidence map for one keyword: search, advertiser, registration, supply, and transaction layers kept separate
keyword-trend-hunter	Discover registration keyword spikes and validate them against new-registration cohort signals
domain-market-beat	Time-bounded market briefing: sales, registration trends, and domain movements with source tiers

Architecture

domainkits plugin
├── .mcp.json                    → remote MCP server (https://api.domainkits.com/v1/mcp)
├── skills/domainkits/SKILL.md   → core skill: tool usage guide (which tool for which task, combining and reporting results)
├── skills/<workflow>/SKILL.md   → 8 bundled workflow skills (brand-protection, domain-analyze, ...)
└── commands/                    → /domainkits:hunt · /domainkits:watch · /domainkits:analyze

No local code execution: the plugin is a remote endpoint, nine skill files, and three command prompts.

Install

Claude Code (CLI, desktop, or VS Code):

/plugin marketplace add ABTdomain/domainkits-plugins
/plugin install domainkits@domainkits

claude.ai / Cowork (as a connector instead of a plugin):

1. Settings → Connectors → Add custom connector
2. Name: DomainKits, URL: https://api.domainkits.com/v1/mcp
3. Start a new conversation

Tiers and limits

Works out of the box, no API key, no sign-up. Plans, limits, and account connection: domainkits.com/mcp. Ask Claude for your "DomainKits usage" anytime to see your tier and remaining quota.

Data and privacy

Queries (domain names, keywords, search filters) are sent to api.domainkits.com to fetch results. The plugin reads no local files and ships no executable code.

Some workflow skills can also use tools you have connected yourself, such as a URL threat check (after asking you), and your client's web search and fetch. Those requests go to those tools, not to DomainKits.

Search and lookup tools are stateless: nothing you ask is retained. Three tools store data across sessions, and only after you enable memory:

Tool	What it stores
monitor	The domains you watch and the results of each check
preferences	Your saved preferences and the memory switch
strategy	Strategy text you wrote, run timestamps and the most recent result

Memory is off by default. When you turn it on, your monitors, preferences, and strategies are encrypted with AES-256-GCM and stored separately for each user, tied to your DomainKits account rather than to a single app. That is what lets you pick them up from any client connected to the same account: Claude Code, claude.ai, or another MCP client. You can delete all of it at any time by asking Claude to delete your DomainKits data (GDPR Article 17).

Responses contain no registrant personal data: WHOIS results carry registrar, dates, status codes and nameservers only.
