概覽

AI 產生的概覽

遠端 MCP 端點，用來稽核網域的郵件送達能力（SPF、DKIM、DMARC、MX），回傳 0-100 評分與修正建議。

可以做什麼: 稽核網域的郵件驗證設定，檢查 SPF、DKIM、DMARC 與 MX 記錄，回傳包含 0-100 送達評分與修正建議的結構化 JSON。同一項稽核提供 GET 與 POST 兩種呼叫方式，都需要傳入網域參數。
適用情境: 適合在啟動郵件行銷、為新網域進行外聯，或排查收件匣投遞與網域信譽問題時使用。不適用於單一電子郵件地址驗證、尋找電子郵件地址或一般 WHOIS/DNS 查詢。
執行需求: 透過 SSE 連線的遠端 MCP 端點，不需要 API 金鑰或註冊。每次呼叫按次付費，透過 Base L2 上的 USDC 以 x402 結算，因此需要支援 x402 且錢包有餘額的用戶端來完成付款挑戰。

安裝前請注意

每次稽核呼叫都會產生費用（每次 0.012 美元，以 Base 上的 USDC 支付），自動化或重複呼叫會從所連線的錢包扣款。付款經由第三方 facilitator（Coinbase CDP、PayAI）處理，被稽核的網域會傳送到遠端服務。

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.Br0ski777%2Femail-deliverability/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。

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"    }  }}

{  "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

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.
