Quick start (hosted)

  "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.

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.
