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, or brand.ai is available
• Explore names across TLDs - See availability for .com, .io, .ai, .co, .dev, .app, .net, .xyz, .org at once
• Real 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

Once installed, you can ask Claude:

"Find me a domain under $15 for my AI startup"

Claude will use search_domains with max_price=15 to find affordable domains, sorted by price.

"I'm building an app that helps remote teams do async standups. Can you brainstorm some domain names?"

Claude will use the brainstorm_domains tool to generate creative suggestions like asynchuddle.com, standupflow.io, etc. - all verified as available with real pricing.

"I'm starting a new AI company called 'NeuralFlow'. Can you check which domain options are available?"

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

"What categories of domains do you have available?"

Claude will use list_categories to show all domain categories with counts.

"What do you think of 'quickpulse.ai' as a domain? Is it any good?"

Claude will use analyze_domain to score it on memorability, brandability, and SEO potential, then give you pros/cons and a verdict.

Slow responses

Rate limiting

The service is free and doesn't require authentication. We ask for reasonable use. If you hit rate limits, results will show status: unknown.
