Domain & Company Intel MCP — by Datakoot

Domain and company intelligence for AI agents. Give an agent a domain or email address and it can vet the company, qualify the lead, or map the target — all from free public data, no API keys.

Tools

Tool	What it does	Source
domain_intel	Registrar, creation/expiry dates, domain age, EPP status, nameservers, DNSSEC, abuse contact	RDAP
dns_lookup	A, AAAA, MX, NS, TXT, CNAME, SOA records	Cloudflare DoH
email_deliverability	MX presence, SPF/DMARC posture, free vs. disposable provider, verdict	Cloudflare DoH
tech_stack	Web server, CMS/framework, CDN, analytics, security headers, page title	Live fetch
subdomains	Subdomain discovery from Certificate Transparency logs	crt.sh
domain_report	One call returns a full dossier: registration + DNS + email deliverability + tech stack, combined	all-in-one

No API keys required for any tool.

Using your Pro key

After subscribing you receive a license key beginning with DATAKOOT-. Pass it as a Bearer token and the free-tier caps are removed:

claude mcp add --transport http --header "Authorization: Bearer DATAKOOT-XXXX-XXXX" domain-intel https://domain.datakoot.com/mcp

The key is validated against Polar on each request (cached briefly). Cancel anytime — access reverts to the free tier automatically.

Self-host (Cloudflare Workers, free tier)

Create a Worker, paste worker.js, deploy. Optional SERVER_API_KEY env var gates access behind Authorization: Bearer <key>. No other configuration needed.
