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%2Floops/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

Loops MCP by usefulapi

Manage Loops contacts, mailing lists, and transactional & event emails from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Loops API key.

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

Connect

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

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

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