Generates narration with word-level timing, sound effects and an original score through the ElevenLabs API (voice, SFX and music), caching each line by hash so unchanged lines cost nothing; configured with an ELEVENLABS_API_KEY (or a key file) and an output format setting, and without a key renders fall back to silent drafts. Includes a list_voices tool to browse the user's ElevenLabs voices and a voice_lines tool to voice every line of an episode's spec.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@3dBlock Studio Make a PS1 horror short about a cursed videotape and show me the script first."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP server that lets any AI make PS1-style low-poly 3D short videos. Give your AI a story; it writes the script, voices it with ElevenLabs, builds the scene in three.js, and renders a vertical 1080x1920 video that loops perfectly. It ships with the engines, a prop library, an 11-role AI film crew and the render pipeline behind the Guess The Horror and Strange History channels.
PS1 low-poly 3D: box people, tiny painted textures, vertex wobble, fog, per-vertex lighting, then real lenses (mm focal lengths, depth of field), bloom, flares, letterbox and colour grades on top.
Living woodcut broadsheets for history stories.
Narration with word-level timing, sound effects and an original score from ElevenLabs, mixed with the voice always on top and normalized to -14 LUFS.
A seamless loop: the last frame is the first frame, and the audio tail crossfades onto the start.

You need Node 18+ and Google Chrome (or Chromium/Edge). ffmpeg comes bundled. The renders run on your computer.

The AI only sends tool calls and code. On your machine the server voices the lines (ElevenLabs, cached), serves the scene to headless Chrome, steps time frame by frame (every scene is a pure function of t), pipes the frames to ffmpeg, mixes the audio with ducking and a loop crossfade, and writes the take next to its thumbnail and contact sheet.
