Blockbench Animation

Wraps the Blockbench MCP tools for creating 3D model animations directly through Claude. You get programmatic control over keyframes, bone rigging, animation curves, and timeline playback without opening the GUI. Useful when you need to generate walk cycles, idle animations, or any bone-based animation through code rather than clicking around. The batch operations for mirroring and scaling keyframes across multiple bones are genuinely handy for symmetrical rigs. Supports standard interpolation types like catmullrom for smooth organic movement and step for robotic stuff. If you're already scripting Blockbench workflows or need to generate animation data programmatically, this handles the tedious keyframe math for you.

Blockbench Animation

Create animations for 3D models using Blockbench MCP tools.

Rig and Motion Decisions

Confirm the format's animation support and intended exporter before animating. Group-based bone_rigging and manage_keyframes operate on Blockbench groups; native armature bones and vertex weights are a separate rig type with their own tools. Do not assume these group tools animate an ArmatureBone merely because it has a similar name. See MCP overview for discovery and format/delivery guidance for target requirements.

Choose the animation type before modeling, because it changes the geometry.

Minecraft supports only rigid bone (node) animation. Split each bend into separate parts at the joint, and overlap them so rotation opens no gaps.
Skinned deformation needs a Generic Model armature with vertex weights, edge loops at joints, and an exporter that carries the rig.
No MCP tools author morph targets. Substitute bones, visibility keyframes, or texture flipbooks.
