semble vs blender-ai-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.; blender-ai-mcp: blender-ai-mcp is a production-shaped MCP server that allows AI clients like Claude, ChatGPT, and Codex to control Blender through a stable, curated tool API. It replaces ad-hoc Python script generation with goal-first routing, deterministic inspection, and safe execution boundaries, enabling more reliable AI-assisted 3D modeling workflows.
