Domain Lookup MCP: Instant Domain Intelligence in Your AI Workflow

Stop switching between terminal windows, browser tabs, and WHOIS tools every time you need domain information. This MCP server puts comprehensive domain lookup capabilities directly into your AI assistant's toolkit.

The Context-Switching Problem

You're deep in a security review, competitive analysis, or infrastructure planning session with your AI assistant. The conversation flows until you hit a domain you need to investigate. Suddenly you're:

• Opening new terminal sessions for dig and whois commands
• Copy-pasting results back into your AI conversation
• Losing context and momentum while gathering basic domain intelligence
• Manually cross-referencing DNS records, registration data, and infrastructure details

This MCP server eliminates that friction entirely.

What You Get

Complete Domain Intelligence: Your AI assistant can instantly pull DNS records (A, AAAA, MX, CNAME, TXT, SOA, NS), WHOIS registration data, and RDAP information for any domain without breaking conversation flow.

Zero Configuration: Built in Go with no external dependencies. Clone, build, point your MCP client at the binary, and you're done.

Fast Queries: Direct system resolver integration means sub-second responses for most lookups.

Real-World Scenarios

Security Research: "Analyze the infrastructure behind suspicious-domain.com" - your AI instantly pulls DNS records, identifies hosting providers, checks registration dates, and spots potential IOCs without you running a single command.

Competitive Intelligence: "Compare the email infrastructure of our top 3 competitors" - get MX records, SPF policies, and hosting details for multiple domains in a single conversation.

Infrastructure Planning: "What DNS setup does enterprise-client.com use?" - instantly see their current configuration to inform your migration or integration strategy.

Due Diligence: "Investigate the technical footprint of this potential acquisition target" - comprehensive domain analysis flows naturally within your broader research conversation.

Integration

Add this to your MCP client configuration:

{
  "mcpServers": {
    "domain-lookup-mcp": {
      "command": "/path/to/domain-lookup-mcp/domain-lookup-mcp",
      "args": [],
      "env": {}
    }
  }
}

Your AI assistant immediately gains domain lookup capabilities. No API keys, no rate limits, no service dependencies.

Setup

git clone https://github.com/dotemacs/domain-lookup-mcp.git
cd domain-lookup-mcp
go build ./...

That's it. The binary handles everything else.

This isn't just another WHOIS wrapper - it's domain intelligence integrated directly into your AI workflow. When every context switch costs you minutes of momentum, having domain data instantly available transforms how you approach investigation and analysis tasks.
