概覽

AI 產生的概覽

遠端 MCP 伺服器，提供網頁與網域查詢：頁面讀取、連結預覽、URL 安全、SEO 稽核、網域/DNS/IP 資料及格式驗證。

可以做什麼
將公開網頁讀取為乾淨的 Markdown，並擷取連結預覽、訂閱來源與網站地圖。檢查 URL 的重新導向、TLS、網域年齡與仿冒特徵，並稽核頁面的 SEO 問題、robots 規則與連結。查詢網域可用性、註冊資訊、DNS 記錄、郵件驗證與濫用聯絡人。解析 IP 地理位置、ASN 與網路歸屬，支援單筆或批次。驗證 IMEI、VIN、IBAN、英國電話與郵遞區號，以及電子郵件地址。
適用情境
適合需要在一處取得即時網頁與網域情報的情境：調查網站、判斷連結是否安全、稽核 SEO、調查網域或 IP，或驗證識別碼與聯絡方式。
執行需求
遠端 streamable HTTP 端點，無需本機安裝。選用的免費 X-API-Key 標頭可將每日免費額度從 100 次提高到 500 次。超出免費額度後，每次呼叫透過 x402 以 USDC 按次付費。
安裝前請注意
超出免費額度的呼叫按次收取 USDC，可能產生實際花費。X-API-Key 標頭屬於憑證，應妥善保密。查詢會將所查 URL、網域、IP 與識別碼傳送給第三方服務。工具為唯讀查詢，但可能揭露你所查詢目標的資訊。
