概览

AI 生成的概览

托管的 Castos MCP 服务器，让助手读取播客与单集、创建或更新单集，并管理私有订阅者。

可以做什么
  • 列出并读取播客，含设置、元数据与可用的 iTunes 分类
  • 列出并读取某个播客的单集，含节目说明与音频信息
  • 创建和更新单集，从公开的 https 链接下载音频并上传
  • 更新播客元数据，如标题、描述与 feed 设置
  • 列出、查找并添加私有订阅者，撤销或恢复其订阅
  • 查看每月工具调用用量并管理付费方案
适用场景
适合在 Castos 上发布播客、希望助手查看节目目录、根据音频链接起草或排期单集，或在不打开 Castos 后台的情况下处理私有 feed 订阅名单的场景。
运行要求
通过 streamable HTTP 连接的远程 MCP 端点，无需本地安装。使用 OAuth 登录，登录页要求填写 Castos API 令牌（在 Castos 账户设置中获取），服务器会校验并按用户保存。客户端配置中不要填写 API 密钥或 Authorization 头。免费方案每月 50 次工具调用。
安装前请注意
多个工具会写入真实的 Castos 账户：创建单集可能立即发布到线上 feed，需检查发布日期；更新单集可能替换音频。撤销私有订阅者会使其失去该私有 feed 的访问权限。单集音频从你提供的公开 https 链接获取，最大 40 MB。Castos API 令牌由第三方托管方保存。付费方案通过 Stripe 结账链接付款，取消后当期不退款。

安装

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.
