What is blender-open-mcp?
Control Blender 3D with natural language prompts via local AI models. It connects MCP clients (Claude, Cursor, or any MCP client) to Blender through a local Ollama LLM. Built on the Model Context Protocol.
How to use blender-open-mcp?
Install prerequisites (Blender 3.0+, Python 3.10+, Ollama, uv). Clone the repo, create a venv with uv, install the package, install the Blender add-on (addon.py), pull an Ollama model (e.g. llama3.2), start Ollama, then run blender-mcp (with optional host/port/model flags). For stdio transport (Claude Desktop, Cursor) use --transport stdio. Use the bundled CLI (blender-mcp-client) or the Python API to interact.
Key features of blender-open-mcp
- Natural language control of Blender via local AI (Ollama)
- Supports multiple MCP transports (HTTP and stdio)
- Full Blender scene inspection and object manipulation
- Material assignment, rendering, and PolyHaven asset integration
- Execute arbitrary Python/bpy code in Blender
- Switch active Ollama model and server URL at runtime
Use cases of blender-open-mcp
- Create and modify Blender scenes using plain English prompts
- Automate repetitive tasks (adding objects, applying materials, rendering)
- Integrate AI-assisted code generation into Blender pipelines
- Browse and import PolyHaven textures and materials
- Control Blender remotely from any MCP-compatible client
常见问题
How do I connect Claude Desktop or Cursor to blender-open-mcp?
Add the server configuration to your `mcp.json` (or `~/.cursor/mcp.json`) with the command `"blender-mcp"` and args `["--transport", "stdio"]`.
Why can't the server connect to the Blender add-on?
Open Blender, go to the 3D Viewport N‑sidebar, find the Blender MCP panel, and click "Start MCP Server". The add‑on listens on port 9876 by default.
What ports does blender-open-mcp use?
FastMCP server: port 8000 (configurable). Blender add‑on TCP socket: port 9876. Ollama: port 11434.
Can I use a different Ollama model?
Yes. Pull any model with `ollama pull <model>` and specify it at server start with `--ollama-model <model>`, or switch it later via the `blender_set_ollama_model` tool.
