Entry point for every 3D or Blender task in this repository - modeling, materials, lighting, cameras, rendering, animation, product shots, environments, cinematic scenes, exports. Classifies the job (fast, standard or cinematic), picks a workflow, asks the registry which library skills to load, then drives Blender through the single `blender` MCP server with render, inspect and refine checkpoints. Use it whenever the user asks to create, change, light, render, animate or export anything in 3D…

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 harness (opened as a project)

The harness's entry skill lives at the root of this repository, where the plugin
install finds it. Read `SKILL.md` in the repository root now and follow it
exactly. For this checkout:

- the harness root `H` is the repository root;
- the Blender tools are `mcp__blender__<tool>`, served from the project `.mcp.json`;
- job folders go to `output/` in the repository root.

The user's request: $ARGUMENTS

If that line is empty, the request is in the conversation.

How to install

The exact contents, by fingerprint

mdr add max-786/claude-3d-harness/blender-harness@sha256:87e88fb56be0c28c

The line at the top of this page pins the label git:20260921.2ec21fb, 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.
