semble vs worldlabs-mcp
semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.; worldlabs-mcp: worldlabs-mcp is a Model Context Protocol gateway to World Labs' Marble and Spark 2.0 engines. It enables generation of navigable 3D worlds from diverse inputs (text, image, video, panorama), real-time streaming via Gaussian splat rendering, and spatial voice agent integration. The project includes a web dashboard, multiple export targets (Resonite, Blender, Unity), and VR headset support.
