generate_hyper3d_model_via_text
Create 3D models in Blender using text descriptions. Generates assets with built-in materials and imports them directly into your scene.
Instructions
Generate 3D asset using Hyper3D by giving description of the desired asset, and import the asset into Blender. The 3D asset has built-in materials. The generated model has a normalized size, so re-scaling after generation can be useful.
Parameters:
text_prompt: A short description of the desired model in English.
bbox_condition: Optional. If given, it has to be a list of floats of length 3. Controls the ratio between [Length, Width, Height] of the model.
Returns a message indicating success or failure.

Implementation Reference
- src/blender_mcp/server.py:706-741 (handler)Handler function decorated with @mcp.tool() that registers and implements the tool.
