Flowcast

FlowCast is an MCP server that turns your AI coding agent into a producer of interactive, narrated walkthroughs — code that types itself out, diagrams that draw themselves, and 3D tours — each a single self-contained HTML file that opens in any browser.

This is the community hub. FlowCast is free to use but closed-source, so there's no code in this repo — just a place to talk with us and with other users.

Get started

npx -y @flowcast/mcp setup

The one-time wizard saves your voice key and connects FlowCast to the AI clients it finds — Claude Code, Claude Desktop, Cursor, Codex, Kiro, Windsurf, Gemini CLI, VS Code. Then just ask your agent:

"Make a whiteboard walkthrough of how the water cycle works."

Where to post

Reporting a good bug

The more of this you include, the faster it gets fixed:

• The prompt you gave your agent

• Which client (Claude Code, Cursor, Codex…) and your OS

• What happened vs what you expected

• A link to (or copy of) the generated .html cast, if relevant
