MCP server + Blockbench plugin that lets AI agents build, texture, animate and render Minecraft-style and low-poly 3D models in Blockbench.
An MCP server and a companion Blockbench plugin that let Claude control Blockbench.
With it, Claude builds models, unwraps UVs, paints textures, adds bones and animations, checks the result with screenshots, and exports the model to any format Blockbench supports. Besides Minecraft-style cube models, it can make low-poly, hand-painted characters. It can also turn a model into pixel art sprites for 2D games.
Every change goes into Blockbench's undo history. Press Ctrl+Z to revert any step you don't like.
------ Version 1.7.1 · Changelog Blockbench 5.2 or later recommended. 5.1.4 also works, but 5.2-only tools return a "requires 5.2" error there. Client Claude Desktop and Claude Code. Developed on Windows. Node.js 18 or later Tools 69
If you use version 1.6.0 or older, update. In older versions, while Blockbench and the MCP server were running, any website open in your browser could connect to the bridge and run code on your computer. 1.6.1 closes this. Details: Security.
Area Coverage ------ Modeling Cubes, meshes, planes, locators, bounding boxes. Groups act as bones in animations. mirror and mirrorelements for symmetric parts. Mesh primitives: plane, pyramid, cylinder, cone, sphere, torus, icosphere, octahedron, dodecahedron. Low-poly Limbs and tubes from cross-sections (addloft). Extrude, inset, loop cut, bevel, solidify, subdivide (editmesh). Taper, bend, twist, smooth (transformmesh).
