Open Models MCP for Blender Using Ollama
Exposes Blender's Python API through FastMCP servers with stdio and HTTP transports, enabling natural language scene manipulation via local Ollama LLMs (llama3.2, Gemma3). Supports 14+ tools for object creation, material assignment, PolyHaven asset integration, rendering, and arbitrary bpy code execution via Claude, Cursor, or CLI clients. Three independent processes—FastMCP server (port 8000), Blender add-on TCP listener (9876), and Ollama (11434)—communicate via HTTP and socket connections, allowing AI-assisted 3D workflows without external APIs.
About Blender-MCP-Server
poly-mcp/Blender-MCP-Server
MCP server addon for Blender - Control Blender via AI agents through 51 powerful tools. Made to be used with PolyMCP for intelligent tool orchestration. Features thread-safe execution, auto-dependency installation, and complete 3D workflow automation.
Implements an HTTP-based MCP server with FastAPI/Uvicorn that exposes Blender's Python API as discrete, discoverable tools—enabling AI agents to autonomously plan and execute multi-step 3D workflows through natural language. Integrates specifically with PolyMCP's agent framework for automatic tool orchestration, error recovery, and state management across operations. The addon uses a thread-safe operation queue to handle concurrent requests safely while auto-installing dependencies and providing real-time execution monitoring through Blender's UI panel.
