概览

AI 生成的概览

远程 MCP 服务器，提供网页与域名查询：页面读取、链接预览、URL 安全、SEO 审计、域名/DNS/IP 数据及格式校验。

可以做什么
将公开网页读取为干净的 Markdown，并提取链接预览、订阅源和站点地图。检查 URL 的重定向、TLS、域名年龄和仿冒特征，并审计页面的 SEO 问题、robots 规则和链接。查询域名可用性、注册信息、DNS 记录、邮件认证和滥用联系人。解析 IP 地理位置、ASN 和网络归属，支持单个或批量。校验 IMEI、VIN、IBAN、英国电话和邮编以及电子邮件地址。
适用场景
适合需要在一处获得实时网页与域名情报的场景：调研网站、判断链接是否安全、审计 SEO、调查域名或 IP，或校验标识符与联系方式。
运行要求
远程 streamable HTTP 端点，无需本地安装。可选的免费 X-API-Key 请求头可将每日免费额度从 100 次提升到 500 次。超出免费额度后，每次调用通过 x402 以 USDC 按次付费。
安装前请注意
超出免费额度的调用按次收取 USDC，可能产生实际花费。X-API-Key 请求头属于凭据，应妥善保密。查询会将所查 URL、域名、IP 和标识符发送给第三方服务。工具为只读查询，但可能暴露你所查询目标的信息。
