Blockbench MCP Plugin
Blockbench MCP plugin enabling AI agents to interact with Blockbench — the popular free 3D modeling editor for Minecraft and voxel game assets — creating and modifying 3D models, managing textures and UV maps, exporting models in various game formats (Bedrock, Java, OBJ), and integrating AI-driven 3D asset creation into Minecraft modding and game development workflows.

Best When
A Minecraft developer or content creator needs AI assistance with Blockbench 3D modeling — for entity models, block models, or resource pack creation.
Avoid When
You need professional 3D modeling for non-Minecraft/voxel content — use Blender or other professional tools.
Use Cases
- • Generating Minecraft Bedrock/Java Edition entity models from design descriptions from game dev agents
- • Modifying block and item model textures from Minecraft content agents
- • Creating custom mob models with animations from Minecraft modding agents
- • Automating repetitive 3D modeling tasks from game asset pipeline agents
- • Building AI-assisted voxel art from creative coding agents
- • Exporting optimized game assets for Minecraft resource packs from packaging agents
Not For
- • High-fidelity 3D modeling (Blockbench is for game-optimized low-poly/voxel models)
- • Non-Minecraft games (though Blockbench supports other formats)
- • Teams using Blender, Maya, or professional 3D tools for non-game content
Interface
Authentication
No authentication — Blockbench plugin communicates locally. Blockbench must be running with the MCP plugin installed.
Pricing
Blockbench and plugin are both free and open source.

Known Gotchas
- ⚠ Blockbench must be running with plugin installed — not a standalone server
- ⚠ Minecraft model format specifics (Bedrock vs Java) affect valid model structures
- ⚠ Very niche community MCP — primarily useful for Minecraft content creators
- ⚠ Plugin API changes with Blockbench updates — verify plugin compatibility
- ⚠ 3D model generation via text is challenging — expect iterative refinement
- ⚠ Texture UV mapping automation requires understanding of Blockbench's UV editor
