概览

AI 生成的概览

托管的 Clearstream MCP 服务器，让助手读取短信名单、订阅者、标签和短信记录，并可发送短信或变更订阅者。

可以做什么
  • 查看账户、发送号码、名单、标签和短信统计
  • 搜索并读取订阅者，包括订阅状态、所属名单和标签
  • 分页浏览收发短信的收件箱历史
  • 向一个或多个号码发送短信
  • 新增订阅者、把号码加入或移出名单，并为最多 100 位订阅者打标签
  • 查看用量、提交功能请求，以及升级或取消付费方案
适用场景
当你使用 Clearstream 做短信触达，希望助手直接回答名单、订阅者和短信量的问题，或在无需打开 Clearstream 后台的情况下完成已获同意的订阅者变更与发送时适用。
运行要求
通过 streamable HTTP 连接的远程端点，无需本地安装。登录使用 OAuth，登录页要求填写在 Clearstream 账户中创建的 API 密钥，子账户密钥还需 Account ID。密钥由服务器按用户保存，不写入客户端配置。免费额度为每月 50 次工具调用。
安装前请注意
发送短信和变更订阅者对真实手机是真实且不可撤销的操作；服务器会要求确认，并要求对每位收件人持有书面同意。登录页会收集 Clearstream API 密钥，由托管服务按用户保存。付费方案为 Pro 每月 9 美元或每年 90 美元、Pro+ 每月 39 美元或每年 390 美元，通过 Stripe 结账链接付款；取消后当期不退款。

README

Clearstream MCP by usefulapi

Use your Clearstream account from Claude, Cursor, or any MCP client. It reads lists, subscribers, texts and statistics, and sends texts or changes subscribers only with written consent. Hosted, no local install: connect with your own credentials.

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

Connect

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

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

On first connect you provide your Clearstream API key, created inside your Clearstream account, and, for a subaccount key only, the Account ID. The server validates it and stores it per user. No keys go in config files.
