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.

Quick Start

Claude Code

claude mcp add domainkits https://api.domainkits.com/v1/mcp

With API key (higher limits):

claude mcp add domainkits https://api.domainkits.com/v1/mcp --header "X-API-Key: YOUR_KEY"

Claude.ai

Connect DomainKits via Settings > Connectors. No manual configuration needed.

Claude Desktop

Edit your config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

macOS / Linux: ``json { "mcpServers": { "domainkits": { "command": "npx", "args": [ "mcp-remote", "https://api.domainkits.com/v1/mcp", "--transport", "http-first" ] } } } ``

Windows: ``json { "mcpServers": { "domainkits": { "command": "cmd", "args": [ "/c", "npx", "mcp-remote", "https://api.domainkits.com/v1/mcp", "--transport", "http-first" ] } } } ``

With API key (higher limits):

macOS / Linux: ``json { "mcpServers": { "domainkits": { "command": "npx", "args": [ "mcp-remote", "https://api.domainkits.com/v1/mcp", "--header", "X-API-Key: your-api-key-here", "--transport", "http-first" ] } } } ``

Windows: ``json { "mcpServers": { "domainkits": { "command": "cmd", "args": [ "/c", "npx", "mcp-remote", "https://api.domainkits.com/v1/mcp", "--header", "X-API-Key: your-api-key-here", "--transport", "http-first" ] } } } ``

Gemini CLI

Edit ~/.gemini/settings.json: ``json { "mcpServers": { "domainkits": { "url": "https://api.domainkits.com/v1/mcp" } } } ``

With API key: ``json { "mcpServers": { "domainkits": { "url": "https://api.domainkits.com/v1/mcp", "headers": { "X-API-Key": "your-api-key-here" } } } } ``

Cursor

Edit ~/.cursor/mcp.json: ``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.
