Purpose
AgentDomainService MCP Server is an MCP (Model Context Protocol) server designed to enable AI assistants such as Claude to check domain availability in real time. Traditional domain registrars usually block automated access through CAPTCHAs and bot detection, whereas this tool wraps the AgentDomainService.com API so that AI can query domain information directly.
Main Capabilities
- Check a single domain: Verify whether any domain (such as yourproject.com, startup.io, brand.ai) is available for registration, returning availability status, purchase price (USD), renewal price, whether it is a premium domain, and alternative suggestions when the domain is taken.
- Explore a name across TLDs: View at once the availability and prices of a name across 9 popular top-level domains including .com, .io, .ai, .co, .dev, .app, .net, .xyz, .org.
- AI brainstorming: Generate creative domain suggestions based on a project description, and verify that these domains are actually available and provide real prices.
- Domain analysis: Perform AI scoring on any domain, covering memorability, brandability, pronunciation, SEO potential (0-10 points), and provide pros, cons, and an overall evaluation.
- Search by price and category: Support filtering by category (such as ai-agents, startup-names, ecommerce), maximum/minimum price, and TLD, and sort by price ascending, descending, or newest, returning a list of available domains.
- List categories: View all available domain categories and their domain counts.
How to Use
This MCP server requires no API key and can be used immediately after installation. For Claude Desktop, add the configuration to ~/Library/Application Support/Claude/claude_desktop_config.json(macOS), then restart Claude Desktop. Manual installation is also supported. After installation, users can ask Claude directly, for example:
- "Is example.com available?"
- "Find me domains under $15"
- "I need a domain for an AI-powered recipe app for busy parents"
- "Analyze coolstartup.com - is it a good domain?"
Claude will call the corresponding MCP tool, the server will query AgentDomainService.com, and the results will be returned and presented to the user by Claude.
Use Cases
- Entrepreneurs brainstorming domains for a new project
- Developers automating domain availability checks
- Brand managers monitoring domain availability
- Domain investors researching opportunities
- Anyone who wants to check domains without CAPTCHAs
Limitations
- The service is free and requires no authentication, but reasonable use is required. If rate limits are triggered, the result will show status: unknown.
- AgentDomainService caches results, so the first query may take 1-2 seconds, and subsequent queries for the same domain will be faster.
- Price information comes from Name.com, and actual purchase and renewal prices may change.
- This tool depends on the availability of the AgentDomainService.com API.
