AI 產生的概覽

託管式 SendGrid 伺服器，讓助理寄送電子郵件，並讀取範本、行銷聯絡人、清單、投遞統計、退信與退訂資料。

可以做什麼
  • 立即寄送真實電子郵件，可使用主旨與內容或動態範本
  • 列出並讀取交易型電子郵件範本及其版本
  • 列出行銷清單、統計聯絡人數量、依完整電子郵件地址查詢聯絡人
  • 新增或更新行銷聯絡人，並可選擇加入清單
  • 依日期範圍讀取全域郵件統計，以及退信與退訂抑制清單
  • 檢查 API 金鑰狀態與權限範圍，並管理用量、方案與功能請求
適用情境
適合讓助理回答 SendGrid 投遞、退信與受眾規模相關問題，或在對話中直接寄送交易型郵件、更新行銷聯絡人。
執行需求
以 URL 方式加入的遠端 MCP 端點，不需安裝套件或本機執行環境。透過 OAuth 登入，登入頁要求填寫 SendGrid API 金鑰，金鑰經驗證後依使用者儲存。免費方案每月 50 次工具呼叫，付費方案另行計費。
安裝前請注意
OAuth 登入時需提供 SendGrid API 金鑰，建議只授予必要權限。sendgrid_send_mail 會立即寄出真實郵件，sendgrid_add_or_update_contacts 會以非同步工作修改行銷聯絡人，執行前應先確認。付費方案涉及付款連結與訂閱，取消後當期不退款。

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.usefulapi%2Fsendgrid/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

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.
