概览

AI 生成的概览

远程 MCP 端点,用于审计域名的邮件送达能力(SPF、DKIM、DMARC、MX),返回 0-100 评分和修复建议。

可以做什么
审计域名的邮件认证配置,检查 SPF、DKIM、DMARC 和 MX 记录,返回包含 0-100 送达评分和修复建议的结构化 JSON。同一审计提供 GET 和 POST 两种调用方式,均需传入域名参数。
适用场景
适合在启动邮件营销、为新域名开展外联,或排查收件箱投递与域名信誉问题时使用。不适用于单个邮箱地址验证、查找邮箱地址或通用 WHOIS/DNS 查询。
运行要求
通过 SSE 连接的远程 MCP 端点,无需 API 密钥或注册。每次调用按次付费,通过 Base L2 上的 USDC 以 x402 结算,因此需要支持 x402 且钱包有余额的客户端来完成支付挑战。
安装前请注意
每次审计调用都会产生费用(每次 0.012 美元,以 Base 上的 USDC 支付),自动化或重复调用会从所连接的钱包扣款。支付经由第三方 facilitator(Coinbase CDP、PayAI)处理,被审计的域名会发送到远程服务。

安装

  1. 打开 控制台中的 Email Deliverability Audit API,将其添加到工作区。

README

Email Deliverability Audit API

[MCP Server] [x402] [License: MIT]

Email deliverability audit for any domain. SPF, DKIM, DMARC, MX validation with score 0-100 and fix recommendations. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "email-deliverability": {      "url": "https://email-deliverability.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl "https://email-deliverability.api.klymax402.com/api/audit?domain=..."# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.
