Was dieses MCP kann

Creates, edits, inspects, renders, saves, and exports editable voxel models with interactive 3D previews.

create_voxel_model

Create voxel model

Create an editable VoxelDraft model from compact commands. Returns a short modelRef for later plugin calls and does not save to Cloud Projects. Use VoxelDraft's compact instruction stream instead of emitting one JSON object per voxel. Coordinates are integers 0..63. Colors are either #RRGGBB or a zero-based palette index. Commands: ["box",x1,y1,z1,x2,y2,z2,color,hollow?] ["ellipsoid",cx,cy,cz,rx,ry,rz,color,hollow?] ["cylinder","x"|"y"|"z",x,y,z,radius,height,color,hollow?] ["line",x1,y1,z1,x2,y2,z2,color] ["roof","x"|"z",x1,y1,z1,x2,y2,z2,color] (gable roof, axis is ridge direction) ["runs","x"|"y"|"z",color,[[x,y,z,length],...]] (preferred exact/freeform representation) ["points",color,[[x,y,z],...]] (sparse details only) ["erase",x1,y1,z1,x2,y2,z2] ["recolor",fromColor,toColor] ["copy",x1,y1,z1,x2,y2,z2,dx,dy,dz] ["repeat",x1,y1,z1,x2,y2,z2,dx,dy,dz,count] ["mirror","x"|"y"|"z",plane,x1,y1,z1,x2,y2,z2] (plane is a grid boundary 0..64) Prefer box/roof/ellipsoid/cylinder for bulk geometry, runs for irregular silhouettes, repeat/mirror for repeated or symmetric parts, and points only for small details. This usually uses far fewer model tokens than raw voxel JSON.

edit_voxel_model

Edit voxel model

Edit the temporary model identified by modelRef and return a new modelRef. This does not modify a saved cloud project. Use VoxelDraft's compact instruction stream instead of emitting one JSON object per voxel. Coordinates are integers 0..63. Colors are either #RRGGBB or a zero-based palette index. Commands: ["box",x1,y1,z1,x2,y2,z2,color,hollow?] ["ellipsoid",cx,cy,cz,rx,ry,rz,color,hollow?] ["cylinder","x"|"y"|"z",x,y,z,radius,height,color,hollow?] ["line",x1,y1,z1,x2,y2,z2,color] ["roof","x"|"z",x1,y1,z1,x2,y2,z2,color] (gable roof, axis is ridge direction) ["runs","x"|"y"|"z",color,[[x,y,z,length],...]] (preferred exact/freeform representation) ["points",color,[[x,y,z],...]] (sparse details only) ["erase",x1,y1,z1,x2,y2,z2] ["recolor",fromColor,toColor] ["copy",x1,y1,z1,x2,y2,z2,dx,dy,dz] ["repeat",x1,y1,z1,x2,y2,z2,dx,dy,dz,count] ["mirror","x"|"y"|"z",plane,x1,y1,z1,x2,y2,z2] (plane is a grid boundary 0..64) Prefer box/roof/ellipsoid/cylinder for bulk geometry, runs for irregular silhouettes, repeat/mirror for repeated or symmetric parts, and points only for small details.

inspect_voxel_model

Inspect voxel model

Inspect a temporary VoxelDraft modelRef. Returns voxel count, command count, bounds, and colors.

load_voxel_project

Load a VoxelDraft project

Load one private Cloud Project and return a short modelRef for later plugin calls. Requires project-read OAuth scope.
