概览

AI 生成的概览

托管式 MailerCheck 连接器,让助手查询验证额度与列表,并在确认后执行异步邮箱验证。

可以做什么
  • 读取账户信息与剩余 MailerCheck 验证额度
  • 浏览验证列表,并查看单个列表的状态与汇总结果统计
  • 提交单个邮箱进行异步验证,稍后读取验证结果
  • 查看本月工具调用用量、提交功能请求,以及管理 Pro 订阅
适用场景
适合让助手查询 MailerCheck 中的邮箱可送达性数据、查看列表验证状态,或在关注额度消耗的前提下验证单个邮箱地址。
运行要求
远程 MCP 端点,仅需添加 URL;客户端配置中不要添加 API 密钥或 Authorization 头。通过托管登录页以 OAuth 登录,需填写 MailerCheck 凭据。需要 MailerCheck 账户;免费方案每月 50 次工具调用。
安装前请注意
验证会消耗 MailerCheck 额度,且需 confirm:true;该调用不会重试,若响应丢失应先到 MailerCheck 查看再重新提交。元工具可发起付费 Stripe Checkout 订阅(Pro 或 Pro+)或取消订阅,当前周期不退款。MailerCheck 凭据需在托管登录页输入。

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.
