概覽

AI 產生的概覽

託管的 Clearstream MCP 伺服器，讓助理讀取名單、訂閱者、標籤與簡訊紀錄，並可發送簡訊或變更訂閱者。

可以做什麼
  • 檢視帳戶、發送號碼、名單、標籤與簡訊統計
  • 搜尋並讀取訂閱者，包含訂閱狀態、所屬名單與標籤
  • 分頁瀏覽收發簡訊的收件匣歷史
  • 向一個或多個號碼發送簡訊
  • 新增訂閱者、將號碼加入或移出名單，並為最多 100 位訂閱者加上標籤
  • 查看用量、提出功能需求，以及升級或取消付費方案
適用情境
當你使用 Clearstream 進行簡訊觸達，希望助理直接回答名單、訂閱者與簡訊量的問題，或在不必開啟 Clearstream 後台的情況下完成已取得同意的訂閱者變更與發送時適用。
執行需求
透過 streamable HTTP 連線的遠端端點，無需本機安裝。登入採用 OAuth，登入頁要求填寫在 Clearstream 帳戶中建立的 API 金鑰，子帳戶金鑰另需 Account ID。金鑰由伺服器依使用者保存，不寫入用戶端設定。免費額度為每月 50 次工具呼叫。
安裝前請注意
發送簡訊與變更訂閱者對真實手機是實際且無法復原的操作；伺服器會要求確認，並要求對每位收件人持有書面同意。登入頁會收集 Clearstream API 金鑰，由託管服務依使用者保存。付費方案為 Pro 每月 9 美元或每年 90 美元、Pro+ 每月 39 美元或每年 390 美元，透過 Stripe 結帳連結付款；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%2Fclearstream/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

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.
