Introduction

Text in, podcast episode out. cast0 turns any text into a published podcast episode in a real RSS feed.

cast0 turns text into podcast episodes that publish to a real RSS feed. Create a podcast (pick a voice, get an API key), send text, cast0 runs OpenAI TTS and updates your feed. Subscribe in any podcast app and listen.

Three ways to create episodes

Pick whichever matches how you generate text.

Agent via MCP. Connect cast0 as an MCP server in Claude Desktop, Claude.ai, Claude Code, Cursor, ChatGPT, Codex, or VS Code. Ask in plain English for an episode. The cleanest agent path. See the MCP server page.
API. POST /api/episodes from any script, app, or terminal. Good for cron jobs, custom pipelines, anything that already speaks HTTP. Start with the Quickstart.
Dashboard. Paste text into the dashboard's manual form. Useful for one-offs and for testing voice settings before you wire up an integration.

For agents that don't speak MCP, you can drop a SKILL.md into Claude Code, Cursor, or OpenClaw instead.
