  "markdown": "# Domain & Company Intel MCP — by Datakoot\n\nDomain 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.\n\n## Tools\n\n| Tool | What it does | Source |\n|---|---|---|\n| `domain_intel` | Registrar, creation/expiry dates, domain age, EPP status, nameservers, DNSSEC, abuse contact | RDAP |\n| `dns_lookup` | A, AAAA, MX, NS, TXT, CNAME, SOA records | Cloudflare DoH |\n| `email_deliverability` | MX presence, SPF/DMARC posture, free vs. disposable provider, verdict | Cloudflare DoH |\n| `tech_stack` | Web server, CMS/framework, CDN, analytics, security headers, page title | Live fetch |\n| `subdomains` | Subdomain discovery from Certificate Transparency logs | crt.sh |\n| `domain_report` | One call returns a full dossier: registration + DNS + email deliverability + tech stack, combined | all-in-one |\n\nNo API keys required for any tool.\n\n## Quick start (hosted)\n\n**Claude Code**\n\n```bash\nclaude mcp add --transport http domain-intel https://domain.datakoot.com/mcp\n```\n\n**Claude Desktop / other clients**\n\n```json\n{\n  \"mcpServers\": {\n    \"domain-intel\": {\n      \"command\": \"npx\",\n      \"args\": [\"mcp-remote\", \"https://domain.datakoot.com/mcp\"]\n    }\n  }\n}\n```\n\n## Try it in 10 seconds — no key, no signup\n\nPaste this into a terminal:\n\n```bash\ncurl -s https://domain.datakoot.com/mcp \\\n  -H 'content-type: application/json' \\\n  -H 'accept: application/json, text/event-stream' \\\n  -d '{\"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"tools/call\", \"params\": {\"name\": \"tech_stack\", \"arguments\": {\"domain\": \"stripe.com\"}}}'\n```\n\nYou get the detected technology stack behind stripe.com — no API key, nothing to sign up for.\n\nOr point any MCP client at the URL and just ask your agent, in plain language:\n\n- \"What tech stack does stripe.com run on?\"\n- \"Is this domain's email configured to prevent spoofing?\"\n\n\n## Example agent workflows\n\n- *\"Is acme.com a real, established business? When was it registered?\"* → `domain_intel`\n- *\"This lead’s email is @acme.io — can it receive mail, is it a throwaway?\"* → `email_deliverability`\n- *\"What’s competitor.com built on?\"* → `tech_stack`\n- *\"Map the public subdomains of target.com\"* → `subdomains`\n\n## Pricing\n\n**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](https://datakoot.com/pricing).\n\nResult lists are capped at 10 items per call on Free and uncapped on Pro.\n\nAll six tools work on the free tier with no key. A paid allowance is shared\nacross all nine Datakoot servers rather than being nine separate buckets, and\nonly a `tools/call` counts — connecting and listing tools are free. Full terms at\n[datakoot.com/pricing](https://datakoot.com/pricing).\n\n**[Subscribe →](https://buy.polar.sh/polar_cl_Q9y3qLrNbtsssN3w5m8SK56oNcruwrmxLEPnd34oAZf)** — one subscription unlocks Pro on every Datakoot server.\n\n### Using your Pro key\n\nAfter subscribing you receive a licence key. Pass it as a Bearer token and the free-tier caps are removed:\n\n```bash\nclaude mcp add --transport http --header \"Authorization: Bearer YOUR-KEY\" domain-intel https://domain.datakoot.com/mcp\n```\n\nThe key is validated against Polar on each request (cached briefly). Cancel anytime — access reverts to the free tier automatically.\n\n## Self-host (Cloudflare Workers, free tier)\n\nThe `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.\n\n## License\n\nMIT. Data from RDAP, Cloudflare DNS, and crt.sh under their respective terms.\n",
