概览

AI 生成的概览

托管式 Loops MCP 服务器:查询、创建、更新和删除联系人,列出邮件列表与自定义属性,并发送事件或事务性邮件。

可以做什么
  • 验证 API 密钥并返回所属团队
  • 按邮箱或 userId 查找联系人,列出邮件列表和自定义联系人属性
  • 创建、更新(不存在则新建)或删除联系人,以及新建自定义联系人属性
  • 发送可触发 Loops 自动化的事件,并按模板发送真实的事务性邮件
  • 查看本月用量、提交功能请求、管理 Pro 订阅
适用场景
适合让助手直接操作 Loops 邮件营销账户:回答联系人和列表相关问题、维护联系人记录,或在对话中触发 Loops 自动化与事务性邮件。
运行要求
远程 streamable HTTP 端点,无需本地安装。配置时只填 URL,通过 OAuth 登录,首次连接需粘贴 Loops API 密钥,密钥会被校验并按用户存储。需要 Loops 账户;免费方案每月 50 次工具调用。
安装前请注意
写入类工具会改动真实数据:可创建、覆盖更新或删除联系人,也可新增属性。发送事件会触发订阅该事件的所有自动化,事务性邮件工具会真正向收件人发出邮件。服务器还提供带 Stripe 结账链接的付费方案和取消订阅工具,助手可能因此发起订阅;任何写入、发送或计费操作前应先确认。Loops API 密钥由第三方托管方保存。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Loops 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。

Web executable,通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体,或 SourceWeft 对话中。智能体会读取该服务器的安装指南,先向你展示发布者、端点和登录方式,经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.usefulapi%2Floops/install.md,并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前,先告诉我它的发布者、端点和登录方式,等我确认。不要把 API 密钥写进命令或我会提交的文件;问我密钥应从哪里获取。

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.
