Domain & Company Intel MCP tools (6, 1 write)

write = sends, deletes, buys or posts

dns_lookupFree
Look up DNS records for a domain via Cloudflare DNS-over-HTTPS. Returns A, AAAA, MX, NS, TXT, CNAME, and SOA records. Use to see where a domain is hosted, who runs its mail and DNS, and what verification/policy TXT records it publishes.
domain_intelFree
Registration intelligence for a domain via RDAP (the modern WHOIS). Returns registrar, creation/expiration/last-changed dates, domain age in years, EPP status codes, nameservers, DNSSEC state, and abuse contact. Use to vet a company, assess a lead, or judge how established a domain is.
domain_reportFree
One-call full dossier on a domain: registration (RDAP), DNS records, email deliverability, and website tech stack, combined into a single report. Use for fast lead qualification, company research, or recon without four separate calls.
email_deliverabilitywrite actionFree
Assess whether a domain (or the domain of an email address) can receive mail and how strong its sender authentication is. Returns MX presence, SPF and DMARC policy, whether it's a free consumer provider (gmail, etc.) or a known disposable/temp-mail provider, and an overall verdict. Use to qualify leads and flag throwaway signups.
subdomainsFree
Discover a domain's public subdomains (app., api., staging., and so on) from Certificate Transparency logs, querying crt.sh and Cert Spotter in parallel and returning whichever answers first. Useful for mapping a company's public attack surface or infrastructure. If both sources are down the call returns an error rather than an empty list.
tech_stackFree
Fingerprint the technology behind a website by fetching its homepage. Detects web server, CMS/framework (WordPress, Shopify, Next.js, etc.), CDN, analytics, and returns the page title, final URL after redirects, and key response headers. Use for competitive research and lead enrichment.

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

No API keys required for any tool.

Quick start (hosted)

Claude Code

claude mcp add --transport http domain-intel https://domain.datakoot.com/mcp

Claude Desktop / other clients

{
  "mcpServers": {
    "domain-intel": {
      "command": "npx",
      "args": ["mcp-remote", "https://domain.datakoot.com/mcp"]
    }
  }
}

Try it in 10 seconds — no key, no signup

Paste this into a terminal:

curl -s https://domain.datakoot.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "tech_stack", "arguments": {"domain": "stripe.com"}}}'

You get the detected technology stack behind stripe.com — no API key, nothing to sign up for.

Or point any MCP client at the URL and just ask your agent, in plain language:

"What tech stack does stripe.com run on?"
"Is this domain's email configured to prevent spoofing?"

Example agent workflows

"Is acme.com a real, established business? When was it registered?" → domain_intel
"This lead’s email is @acme.io — can it receive mail, is it a throwaway?" → email_deliverability
"What’s competitor.com built on?" → tech_stack
"Map the public subdomains of target.com" → subdomains

Pricing

Free — 100 calls a day, keyless, no signup. Pro — $15/mo including 50,000 calls a month with no daily limit; one key unlocks all nine Datakoot servers. Go over the monthly allowance and you drop to free-tier speed for the rest of the month, or top up — never cut off, no metered overage. Full terms: datakoot.com/pricing.

Result lists are capped at 10 items per call on Free and uncapped on Pro.

All six tools work on the free tier with no key. A paid allowance is shared across all nine Datakoot servers rather than being nine separate buckets, and only a tools/call counts — connecting and listing tools are free. Full terms at datakoot.com/pricing.

Subscribe → — one subscription unlocks Pro on every Datakoot server.

Using your Pro key

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

claude mcp add --transport http --header "Authorization: Bearer YOUR-KEY" 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)

The worker.js in this repository is a snapshot of the hosted server, not a live mirror of it — the hosted endpoint is deployed independently and may be ahead. Create a Worker, paste worker.js, deploy.
