概览

AI 生成的概览

托管式 SendGrid 服务器，让助手发送邮件，并读取模板、营销联系人、列表、投递统计、退信和退订数据。

可以做什么
  • 立即发送真实邮件，可使用主题与正文或动态模板
  • 列出并读取事务性邮件模板及其版本
  • 列出营销列表、统计联系人数量、按精确邮箱查找联系人
  • 新增或更新营销联系人，并可选加入列表
  • 按日期范围读取全局邮件统计，以及退信和退订抑制列表
  • 检查 API 密钥状态与权限范围，并管理用量、套餐和功能请求
适用场景
适合让助手回答 SendGrid 投递、退信和受众规模相关问题，或在对话中直接发送事务性邮件、更新营销联系人。
运行要求
以 URL 方式添加的远程 MCP 端点，无需安装包或本地运行时。通过 OAuth 登录，登录页要求填写 SendGrid API 密钥，密钥经校验后按用户存储。免费套餐每月 50 次工具调用，付费套餐另行计费。
安装前请注意
OAuth 登录时需提供 SendGrid API 密钥，建议只授予必要权限。sendgrid_send_mail 会立即发出真实邮件，sendgrid_add_or_update_contacts 会以异步任务修改营销联系人，执行前应确认。付费套餐涉及支付链接和订阅，取消后当期不退款。

安装

  1. 打开 控制台中的 SendGrid MCP by usefulapi，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

README

SendGrid MCP by usefulapi

Live endpoint: https://sendgrid.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://sendgrid.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http sendgrid https://sendgrid.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": {    "sendgrid": {      "url": "https://sendgrid.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 SendGrid credentials.

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

On first connect you'll paste your SendGrid API key (SendGrid → Settings → API Keys). It's validated, stored per-user, and scoped to you — no keys in config files.
