// Create and manage animations in Blockbench using MCP tools. Use when animating 3D models, creating keyframes, managing bone rigs, editing animation curves, or working with animation timelines. Covers walk cycles, idle animations, combat animations, and complex multi-bone animations.
Overview of the Blockbench MCP server tools, resources, and prompts. Use to understand the full MCP capability set, learn how tools work together, or when starting a new Blockbench project. Covers all domains (modeling, animation, texturing, PBR, UI, camera) and their MCP interfaces.
Create and edit 3D models in Blockbench using MCP tools. Use when building geometry with cubes, creating meshes, placing spheres/cylinders, editing vertices, extruding faces, or organizing models with groups. Covers both cube-based Minecraft modeling and freeform mesh editing.
MANDATORY prerequisite — invoke BEFORE any mcp__blockbench__* tool call that creates, modifies, or exports Blockbench content. Orchestrates the other blockbench-* skills (modeling, texturing, animation, PBR, Hytale, MCP overview). Trigger on: 3D model/texture/animation creation or edits in Blockbench; calls to mcp__blockbench__* tools; phrases like 'build a Minecraft model', 'paint a texture', 'animate this rig', 'export the model'. Dispatches to the right sub-skill(s), enforces pre-flight checks (project open, format, outline), wraps risky work in checkpoints, and ensures exports close the loop.
Blockbench plugin/extension development for the 3D modeling tool. Use when creating, modifying, or debugging JavaScript plugins for Blockbench including actions, dialogs, panels, menus, toolbars, model manipulation, animation APIs, and custom formats/codecs. Triggers on Blockbench plugin, Blockbench extension, Blockbench API, BBPlugin, model editor plugin, or 3D modeling tool extension.
Create Hytale models and animations using Blockbench MCP tools. Use when working with Hytale character/prop formats, creating attachments, setting shading modes, using quads, or animating with visibility keyframes. Requires the Hytale Blockbench plugin to be installed.
Create and manage PBR (Physically Based Rendering) materials in Blockbench using MCP tools. Use when working with texture_set.json files, creating normal/height/MER maps, configuring material properties for Minecraft Bedrock RTX, or setting up multi-channel texture workflows.
