Castos MCP by usefulapi

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:

{
  "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.
