Overview

Description from the maker (original English)

Domain intel for AI agents: RDAP registration, DNS, email deliverability, tech stack.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Before you install

  • Basic checks: 1 of 1 passed

Common questions

Is Domain & Company Intel MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

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.

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 →](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:

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.
