概覽

AI 產生的概覽

遠端 MCP 伺服器,讓助理依據免費公開資料查詢網域註冊、DNS、郵件可達性、技術堆疊與子網域。

可以做什麼
  • 查詢網域註冊資訊:註冊商、建立與到期日期、網域年齡、EPP 狀態、名稱伺服器、DNSSEC 與濫用聯絡人
  • 透過 DNS-over-HTTPS 查詢 A、AAAA、MX、NS、TXT、CNAME、SOA 記錄
  • 檢查郵件可達性:是否有 MX、SPF/DMARC 設定、免費或一次性信箱供應商,並給出結論
  • 辨識網站技術堆疊:Web 伺服器、CMS 或框架、CDN、分析工具、安全標頭與頁面標題
  • 從憑證透明度日誌探索子網域
  • 一次呼叫回傳註冊、DNS、郵件與技術堆疊的完整彙整報告
適用情境
適合需要依網域或電子郵件地址核實公司或潛在客戶、判斷網域是否長期存在、評估郵件防偽造設定,或了解競爭對手公開網站技術堆疊的情境。
執行需求
需要可連線的遠端 MCP 端點(streamable HTTP);免費層不需 API 金鑰、註冊或環境變數。付費授權金鑰以 Authorization Bearer 標頭傳入,用以解除免費層限制。需要能連上託管端點的網路。
安裝前請注意
免費層每天限 100 次呼叫,結果清單最多 10 筆;Pro 為每月 15 美元,額度在該供應商的多個伺服器間共用。查詢的網域或電子郵件會傳送到託管服務及其上游來源(RDAP、Cloudflare DoH、crt.sh、即時抓取)。授權金鑰每次請求都會向 Polar 驗證。自架的 worker.js 僅為快照,可能落後於託管端點。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Domain & Company Intel MCP,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable,透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式,或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南,先向你展示發布者、端點和登入方式,經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.selflabbs%2Fdomain-intel-mcp/install.md,並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前,先告訴我它的發布者、端點和登入方式,等我確認。不要把 API 金鑰寫進命令或我會提交的檔案;問我金鑰應從哪裡取得。

其他 MCP 客戶端

把它新增到你客戶端的 mcpServers 設定中。

README

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

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"]    }  }}

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"}}}'

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

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.
