Dev Launches Hosted MCP Server for Domain Intel: WHOIS, DNS, Live SSL, Subdomains
ayitmeadudeman · reddit · 2026-10-05
A developer put a remote MCP server in front of a domain intelligence API so agents can query WHOIS/RDAP, DNS records, live SSL certs, live subdomains, and SPF/DKIM/DMARC directly.
Key points:
- Connect via Streamable HTTP with no auth: claude mcp add --transport http domain-intelligence https://oti-labs.com/mcp; configs for Cursor, VS Code, Windsurf, Claude Desktop
- Six read-only tools, including domainlookup (all-in-one) and subdomains (stripe.com: 273 live of 458 found), kept separate from CT-log-only names
- Agent-friendly design: limit args to avoid blowing context windows, read-only flags for auto-approval, actionable plain-sentence errors
- Free tier: 1,000 lookups/month without a key, +1,000 with a free RapidAPI key, $9.99/month for 50,000
- MIT-licensed code on GitHub
