From a sentence to a model you can turn around.

Describe one object and get back a self-contained glTF binary with textures, pictures of the finished model from six sides, the picture it was made from, and a provenance file that records exactly how it was made. Choose economy for a compact model in minutes, high for full detail, or max, which takes longer to refine the shape for finer surface detail. Geometry is unitless: no physical size, rigging, watertightness or print readiness is inferred from a description.

One sentence at high and max, all real jobs. Pick an example, drag the divider to compare, and drag the model to turn it.

“a fierce dragon statue carved from dark green jade, coiled on a rough stone base with its wings folded and its jaws open, polished highlights on the scales” at high and max.

Input: A description of up to 4,000 characters; no file
Outputs: model.glb, model.web.glb, model_preview.png, six single views, model_views.json, reference.png and generation.json
Quality: economy: about 120,000 faces, 1024 × 1024 PBR textures · high: 2048 × 2048 textures, about one million faces · max: high plus an extra geometry refinement pass for finer surface detail; takes longer
Duration: Asynchronous; one-hour deadline including queueing and execution

Just words.

No photos, no modeling skills. Describe the object and its materials, and the model arrives as a file.

Ready for your tools.

One standard GLB file with realistic materials, for Blender, Unity, Unreal or a web page.

Light or detailed.

Economy keeps the file light. High adds finer shape and sharper textures. Max refines the shape further for finer surface detail, and takes longer.

Claude CodeOAuth or API key

The first form signs in through the browser when you run /mcp. In .mcp.json (project root), ${MCPBYTES_API_KEY} is read from the environment when Claude Code connects. Claude Code docs

Codex (CLI, IDE extension, ChatGPT desktop)OAuth or API key

Codex reads the key from the environment variable each time it connects. The same table can go in ~/.codex/config.toml by hand; codex mcp add has no --header flag. Codex docs

create_3d_model: Create a textured 3D model from a description. Returns model.glb, model.web.glb (Draco + WebP, for browsers and engines), model_preview.png (the finished model rendered from six sides on one labeled sheet; get_job also returns it as an image), model_{front,back,left,right,top,bottom}.png (each view alone), model_views.json (each view's camera and the SHA-256 of model.glb), reference.png (the generated source image the model was built from, not a render of it) and generation.json. This is an asynchronous job; use get_job to follow progress. A failed job is refunded. quality: economy, texture_resolution: 1024: 50 credits. quality: high, texture_resolution: 2048: 75 credits. quality: max, texture_resolution: 2048: 150 credits. Requires idempotency_key; retain it when retrying the same request.
create_upload: Returns a one-hour URL to PUT a local file to; then call the tool with the upload_id.
get_job: Status and results of a job; waits up to wait_seconds for it to finish.
cancel_job: Cancel a queued job or a workflow whose can_cancel is true; repeated calls never delete results.
list_jobs: Your most recent jobs, newest first.
read_job_file: Reads a text output (.txt .json .md .csv) of a succeeded job in chunks.
