# 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.
## Quick start (hosted)
**Claude Code**
```bash
claude mcp add --transport http domain-intel https://domain.datakoot.com/mcp
```
**Claude Desktop / other clients**
```json
{
"mcpServers": {
"domain-intel": {
"command": "npx",
"args": ["mcp-remote", "https://domain.datakoot.com/mcp"]
}
}
}
```
## 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 | Pro | Team |
|---|---|---|---|
| Price | $0 | $15/mo | $49/mo |
| Calls included | 100 per day | 10,000 per month | 50,000 per month |
| Past the allowance | refused until 00:00 UTC | $5 per 1,000 | $5 per 1,000 |

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](https://datakoot.com/pricing).
**[Subscribe →](https://buy.polar.sh/polar_cl_Q9y3qLrNbtsssN3w5m8SK56oNcruwrmxLEPnd34oAZf)** — 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:
```bash
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.
