Transport: Streamable HTTP

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to datakoot.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP server that gives an assistant domain and company intelligence: RDAP registration, DNS records, email deliverability, tech stack and subdomains.

What you can do: Look up domain registration details such as registrar, dates, domain age, EPP status, nameservers, DNSSEC and abuse contact
Query DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA) to see hosting, mail and DNS providers
Assess email deliverability and sender authentication, including MX presence, SPF/DMARC posture and free or disposable providers
Fingerprint a website's tech stack: web server, CMS/framework, CDN, analytics, page title and response headers
Discover public subdomains from Certificate Transparency logs
Get a combined dossier of registration, DNS, email and tech stack in one call
When to use it: Useful when an assistant needs to vet a company or lead from a domain or email address, judge how established a domain is, research a competitor's technology, or map a target's public subdomains and attack surface.
Requirements: A remote MCP endpoint at domain.datakoot.com/mcp over streamable HTTP; no API keys or signup needed for the free tier. Clients that only support stdio can bridge it with npx mcp-remote. An optional Pro licence key is passed as an Authorization Bearer header.

Before you install

Free tier is limited to 100 calls a day and result lists are capped at 10 items; Pro is a paid subscription ($15/mo) whose key is validated against a third-party billing service. Queries about domains and email addresses are sent to the hosted endpoint and to external sources such as RDAP, Cloudflare DoH, crt.sh and Cert Spotter. Subdomain discovery is intended for public attack-surface mapping, so only use it on domains you are authorized to assess.

Installation

In SourceWeft

Open Domain & Company Intel MCP in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.datakoot%2Fdomain-dns-whois/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

`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.

json

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

{  "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:

bash

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"}}}'

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:

bash

claude mcp add --transport http --header "Authorization: Bearer YOUR-KEY" domain-intel https://domain.datakoot.com/mcp

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.

Tools

domain_report

Domain Report

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.

Parametersdomainrequired

domain_intel

Domain Intel

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.

Parametersdomainrequired

dns_lookup

DNS Lookup

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.

Parameterstypesdomainrequired

email_deliverability

Email Deliverability

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.

Parametersdomain_or_emailrequired

tech_stack

Tech Stack

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.

Parametersdomainrequired

subdomains

Subdomains

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.
