AgentDomainService MCP Server
An MCP (Model Context Protocol) server that enables AI assistants like Claude to check domain availability in real-time. Powered by AgentDomainService.com.
Why This Exists
The Problem: AI assistants can't help you check if a domain is available. Traditional registrars like GoDaddy and Namecheap block automated access with CAPTCHAs and bot detection.
The Solution: AgentDomainService provides a simple API that AI can use. This MCP server wraps that API so Claude and other MCP-compatible assistants can check domains directly.
Features
Price Filtering - Find domains within your budget (e.g., under $15)
Category Search - Browse domains by category (AI agents, startups, e-commerce, etc.)
AI Brainstorming - Describe your project and get creative domain suggestions that are actually available
Domain Analysis - AI-powered scoring for memorability, brandability, and SEO potential
Check any domain - Verify if
yourproject.com,startup.io, orbrand.aiis availableExplore names across TLDs - See availability for
.com,.io,.ai,.co,.dev,.app,.net,.xyz,.orgat onceReal pricing - See actual purchase and renewal prices from Name.com (not just WHOIS/DNS checks)
No API keys required - Just install and use
No CAPTCHAs - AgentDomainService handles all the complexity

Claude will use the explore_name tool to check neuralflow.com, neuralflow.io, neuralflow.ai, etc. and show you which are available with pricing.
