概覽

AI 產生的概覽

託管的 Nylas MCP 伺服器，讓助理讀取已連結帳號的郵件、行事曆、活動與聯絡人，並可寄送郵件或建立行程。

可以做什麼
  • 列出並檢視已連結帳號（grant）與郵件資料夾
  • 列出並讀取郵件與草稿
  • 列出行事曆與活動，並讀取單一活動
  • 列出並讀取聯絡人，可依電子郵件或電話篩選
  • 寄送真實郵件、建立草稿或建立行事曆活動
  • 查看用量、提出功能需求、升級或取消訂閱
適用情境
適合讓助理整理收件匣、摘要某位寄件人的郵件、查看本週會議、查詢聯絡人，或透過 Nylas 連結的帳號起草與寄送郵件、建立行程邀請。
執行需求
遠端 streamable HTTP 端點，無需本機安裝。只需填入伺服器網址，接著在伺服器的 OAuth 登入頁以 Nylas 憑證登入；首次連線時需貼上 Nylas API 金鑰，金鑰會經驗證並依使用者儲存。免費方案每月 50 次工具呼叫。
安裝前請注意
寄送郵件與建立活動是真實操作，會送達收件者且可能寄出邀請，執行前應先確認。伺服器會索取 Nylas API 金鑰，該金鑰可存取你已連結的帳號。付費方案透過付款連結結帳，取消後服務持續到已付費期間結束，當期不退費。用量按月計算。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Nylas MCP by usefulapi，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

README

Nylas MCP by usefulapi

Read your email, calendars, events and contacts, and send email or create events, from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Nylas API key.

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

Connect

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

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

On first connect you'll paste your Nylas API key. It's validated, stored per-user, and scoped to you.
