Convert an MMD (MikuMikuDance) PMX/PMD model into a clean Humanoid-rig model inside Blender via the Blender MCP. Use this skill whenever the user wants to convert, retarget, clean up, or "humanoid-ify" an MMD model in Blender — including removing MMD-specific bones (twist/IK/center/group bones), transferring vertex weights onto the real arm/leg bones, fixing the downward-pointing waist bone, renaming bones to the Humanoid convention (Hips/Spine/UpArm/ForeArm/Hand/UpLeg/Leg/Foot/Toe), splitting the mesh into parts, and renaming Japanese shape keys. Trigger this even if the user only says "I imported an MMD model and want to use it in Unity/MotionBuilder" or "make this MMD model usable for our rig," since that is exactly this workflow.
