DomainKits - domain name data and intelligence

通过 MCP 服务查询域名可用性、WHOIS、DNS 及注册趋势,覆盖域名全生命周期。

它能做什么

DomainKits 是一个 MCP 服务器,让 AI 直接查询域名数据。搜索类工具覆盖新注册、长期持有、即将删除、刚刚删除、当前活跃以及二手市场上的域名,并支持拼写变体枚举和名称服务器反查。查询类工具返回可用性与价格、WHOIS/RDAP、DNS 记录、Safe Browsing 安全状态、跨 TLD 可用性、关键词数据以及外链概况。趋势类工具反映热门关键词与 TLD 注册走势。批量工具一次最多校验 50 个域名。状态类工具可保存偏好、监控域名变更、记录分析策略。支持 Claude Code、Claude.ai、Cursor 等 MCP 客户端。

什么时候用它

  • 为新项目挑选可注册的域名
  • 调查某个域名的 WHOIS 历史和当前 DNS 配置
  • 批量监控一组域名的 WHOIS、DNS 或页面变更
  • 发现新注册域名里的趋势关键词与 TLD 走向

常见问题

必须使用 API 密钥吗?
不需要。无密钥即可作为访客使用,大多数工具限速为每分钟 5 次、每天 10 次;注册免费会员可放宽限制,更高级别(Premium、Platinum)提供更高额度。
数据来源是什么?
文档明确提到 Google Safe Browsing 用于安全检查、Google Ads 用于关键词数据,活跃域名来自约 2.4 亿条 gTLD 库;WHOIS 与 DNS 通过标准协议获取,其他上游供应商未在文档中说明。
会保存我的数据吗?
记忆功能默认关闭,需用户明确同意;已存储的数据使用 AES-256-GCM 加密,文档声明符合 GDPR,可通过 preferences 工具随时删除。
能直接给出可注册的域名建议吗?
可以按关键词脑暴候选,再用 bulk_available 一次校验最多 50 个,并返回可用域名的价格。更上层的命名、尽调等流程文档在配套的 GitHub 仓库 DomainKits Skills 中。
