Build, render, and visually verify 3D models with Blender's Python API in headless mode, using the image tool to inspect renders and iterate.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Blender Headless Modeling Use this when the user wants a 3D model, scene, or render produced locally with Blender and no Blender MCP server is configured. ## Locate Blender 1. Try `which blender`, then platform defaults: `/Applications/Blender.app/Contents/MacOS/Blender`, `/usr/bin/blender`, `/snap/bin/blender`, `%ProgramFiles%\Blender Foundation\Blender*\blender.exe`. 2. Confirm with `<blender> --version` and note the major version; the Python API changes between releases. ## Build with a script 1. Write one `build_<name>.py` that resets the scene (`bpy.ops.wm.read_factory_settings(use_empty=True)`), builds geometry with `bpy.ops.mesh.primitive_*` or `bmesh`, assigns materials, adds a camera and lights, sets `scene.render.filepath` to an absolute path, and renders with `bpy.ops.render.render(write_still=True)`. 2. Keep every file write comfortably under the model output limit: build large scripts in parts (a base file, then `edit` calls that append helpers) instead of one huge `write`. A tool call cut off by the output limit loses its arguments. …

How to install
mdr add metaspartan/cybara/blender-headless@sha256:6c7eef40a95d1ce5The line at the top of this page pins the label git:20260907.0d9260e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
