This MCP server integrates with World Labs Marble and Spark 2.0 to generate, manage, and interact with navigable 3D worlds. Key capabilities include:

World Generation

• Generate 3D worlds from text descriptions, public image URLs (including panoramas), multiple images at specific angles, or public video URLs

• Upload local image/video files and generate worlds end-to-end, or use a two-step signed upload flow

World Management

• List (paginated), get details, and delete worlds

• Display worlds as rich visual cards with thumbnails, badges, and direct viewer links

Operation Monitoring

• Poll generation operation status manually or block-wait until completion (configurable timeout)

Spatial Scene Augmentation

• Place spatialized looping audio at 3D coordinates (via WebAudio)

• Embed virtual TV screens playing videos in the 3D scene

• Spawn animated agent avatars grounded on the collider mesh

• Broadcast spatial voice notifications (Gemini TTS) at specific 3D locations

AI & Utilities

• Refine short prompts into detailed, Marble-optimized descriptions using a local Ollama LLM

• Stream worlds via Spark 2.0 renderer with VR/XR headset support (Quest, Pico, Vive)

• Export worlds to Blender, Unity3D, and other DCC tools

• Access full API reference documentation at multiple detail levels

Allows exporting generated 3D worlds to Blender for further editing and asset creation.

Allows exporting generated 3D worlds to Unity3D for game development and interactive experiences.

1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@worldlabs-mcp Create a 3D world from 'snowy mountain village at dusk'"

That's it! The server will respond to your query, and you can continue using it as needed.
