uvx blender-mcp
uvx blender-mcp install-addon

Usage

• •Install uv first using its official installer (not pip install uv), then configure your MCP client with 'uvx blender-mcp'.
• •Install the addon (uvx blender-mcp install-addon), enable 'Interface: Blender MCP' in Blender Preferences, then press N and click Start MCP Server in the BlenderMCP tab.
• •Only run one instance of the server (either Cursor or Claude Desktop), not both.
• •For AI-generated or downloaded assets, store Sketchfab/Hyper3D/Hunyuan3D credentials in the Blender addon preferences or env vars.

Key features

• ✓Two-way communication via a socket-based JSON protocol between the Blender addon and the MCP server.
• ✓Create, modify and delete 3D objects; apply materials; inspect scenes; execute arbitrary Python code in Blender.
• ✓Poly Haven assets/HDRIs, Sketchfab model search, and AI-generated 3D models via Hyper3D Rodin and Hunyuan3D.
• ✓Persistent API credentials via Blender Add-on Preferences or environment variables.
• ✓Anonymous usage telemetry on by default; disable with DISABLE_TELEMETRY=true.

Best for

Prompt-driven 3D modeling and scene building inside Blender with Claude or other MCP clients.

Caveats

• ⚠execute_blender_code runs arbitrary Python in Blender and is dangerous in production; always save work before using it.
• ⚠Telemetry is on by default and may be used for research and AI model training (opt out via env var or the addon checkbox).
• ⚠Requires Blender 3.0+, Python 3.10+, and uv; GUI-launched clients may fail with 'spawn uvx ENOENT' unless uvx's full path is set.
• ⚠Third-party integration, not made by Blender.
