概覽

AI 產生的概覽

託管的 Castos MCP 伺服器，讓助理讀取播客與單集、建立或更新單集，並管理私有訂閱者。

可以做什麼
  • 列出並讀取播客，含設定、中繼資料與可用的 iTunes 分類
  • 列出並讀取某個播客的單集，含節目說明與音訊資訊
  • 建立和更新單集，從公開的 https 連結下載音訊並上傳
  • 更新播客中繼資料，如標題、描述與 feed 設定
  • 列出、查找並新增私有訂閱者，撤銷或恢復其訂閱
  • 查看每月工具呼叫用量並管理付費方案
適用情境
適合在 Castos 上發布播客、希望助理檢視節目目錄、依音訊連結草擬或排程單集，或在不開啟 Castos 後台的情況下處理私有 feed 訂閱名單的情境。
執行需求
透過 streamable HTTP 連線的遠端 MCP 端點，無需本機安裝。以 OAuth 登入，登入頁要求填寫 Castos API 權杖（在 Castos 帳戶設定中取得），伺服器會驗證並依使用者儲存。用戶端設定中不要填 API 金鑰或 Authorization 標頭。免費方案每月 50 次工具呼叫。
安裝前請注意
多個工具會寫入實際的 Castos 帳戶：建立單集可能立即發布到線上 feed，需檢查發布日期；更新單集可能替換音訊。撤銷私有訂閱者會使其失去該私有 feed 的存取權。單集音訊從你提供的公開 https 連結取得，最大 40 MB。Castos API 權杖由第三方託管方保存。付費方案透過 Stripe 結帳連結付款，取消後當期不退款。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Castos 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。

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%2Fcastos/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

Castos MCP by usefulapi

Use your Castos account from Claude, Cursor, or any MCP client. Read podcasts and episodes, create and update episodes, and manage private subscribers. Hosted, no local install: connect with your own credentials.

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

Connect

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

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

On first connect you provide your Castos API token (account avatar → Account Settings → Publish Settings). The server validates it and stores it per user. No keys go in config files.
