Nothing serious here today

Today is the operative word: we check VoxelDraft – AI Voxel Modeling every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

voxel

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.

list_voxel_projects

List private VoxelDraft Cloud Projects. Requires project-read OAuth scope.

edit

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. This usually uses far fewer model tokens than raw voxel JSON.

export

export_voxel_model

Create direct download URLs for OBJ+MTL or compact VoxelDraft JSON from a modelRef.

inspect

inspect_voxel_model

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

load

load_voxel_project

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

render

render_voxel_model

Preview a VoxelDraft modelRef. ChatGPT can render an interactive Three.js/WebGL widget; everyone also receives an interactive WebGL URL. Signed-in VoxelDraft Plus users may additionally receive a cached PNG when includeImage is true.

save

save_voxel_model

Save the temporary model identified by modelRef to private VoxelDraft Cloud Projects. Requires project-write OAuth scope. Pass projectId to update an existing owned cloud project.

VoxelDraft – AI Voxel Modeling — questions

Answers built from our own checks of this server.

What can VoxelDraft – AI Voxel Modeling do?

It exposes 8 tools, read directly from the server on our last check. Among them: create_voxel_model, edit_voxel_model, export_voxel_model, inspect_voxel_model, list_voxel_projects, load_voxel_project and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is VoxelDraft – AI Voxel Modeling working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 113 ms. The bar chart above shows every period we have measured.

How do I connect VoxelDraft – AI Voxel Modeling?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does VoxelDraft – AI Voxel Modeling need an API key?

Yes. Every time we knock, VoxelDraft – AI Voxel Modeling answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is VoxelDraft – AI Voxel Modeling?

It answers our handshake in 113 ms on average, which is faster than 89% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
