Recent Changes

The following major features and improvements are available in the current release (2.0.4):

  • Renamed to mcp-for-blender: The PyPI package blender-mcp is now mcp-for-blender. Existing setups keep working (uvx blender-mcp still runs the server) and no config change is required, but new installs should use mcp-for-blender. See the announcement.
  • Safe mode: Set BLENDER_MCP_SAFE_MODE=1 to check every script before it runs in Blender and block risky code.
  • Scene export: export_scene exports the scene, the selection, or named objects to GLB/FBX.
  • API lookups: describe_node_type and bpy_api_lookup let the AI read node schemas and the bpy API reference instead of guessing socket order or enum names.
  • Connection flags: --host and --port CLI flags for running several Blender instances side by side.
  • Docker image: Run the MCP server in a container while Blender runs on your machine.
  • Poly Pizza integration: Import low-poly models directly from the Poly Pizza library of over 10,600 free assets.
  • Hunyuan3D integration: Generate 3D models from text or images using Tencent's Hunyuan3D, including International (Pro) Tencent Cloud accounts.
  • Addon version handshake: The MCP server checks the installed addon's version on connect and logs how to update it if it is behind.
  • Persistent credentials: API keys for Sketchfab, Poly Pizza, Hyper3D Rodin, and Hunyuan3D are saved in Blender's Add-on Preferences and survive restarts.
