概覽

AI 產生的概覽

託管式 MailerCheck 連接器,讓助理查詢驗證額度與清單,並在確認後執行非同步電子郵件驗證。

可以做什麼
  • 讀取帳戶資訊與剩餘 MailerCheck 驗證額度
  • 瀏覽驗證清單,並查看單一清單的狀態與彙總結果統計
  • 提交單一電子郵件進行非同步驗證,稍後讀取驗證結果
  • 查看本月工具呼叫用量、提出功能請求,以及管理 Pro 訂閱
適用情境
適合讓助理查詢 MailerCheck 中的電子郵件送達率資料、檢視清單驗證狀態,或在留意額度消耗的前提下驗證個別電子郵件地址。
執行需求
遠端 MCP 端點,僅需加入 URL;用戶端設定中不要加入 API 金鑰或 Authorization 標頭。透過託管登入頁以 OAuth 登入,需填寫 MailerCheck 憑證。需要 MailerCheck 帳戶;免費方案每月 50 次工具呼叫。
安裝前請注意
驗證會消耗 MailerCheck 額度,且需 confirm:true;此呼叫不會重試,若回應遺失應先到 MailerCheck 查看再重新提交。中繼工具可發起付費 Stripe Checkout 訂閱(Pro 或 Pro+)或取消訂閱,目前週期不退款。MailerCheck 憑證需在託管登入頁輸入。

README

MailerCheck MCP by usefulapi

https://mailercheck.usefulapi.io/mcp

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://mailercheck.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http mailercheck https://mailercheck.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "mailercheck": {      "url": "https://mailercheck.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your MailerCheck credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/mailercheck/

Connect your own MailerCheck credentials through the hosted sign-in page.
