video-generation-mcp
An MCP server that makes narrated "tech explained" reels for Facebook, Instagram and YouTube Shorts: script → Gemini voice → line timings → 3D (three.js) or 2D visuals → background render → music mix → final mp4. It also makes white editorial image posts, step-by-step infographics, thumbnails, captions and other formats.
Built with FastMCP for Claude Desktop, Claude Code and any MCP client.
