This CLI is installed as part of the cli-anything-blender package:
pip install cli-anything-blender
Prerequisites:
- Python 3.10+
- blender (>= 4.2) must be installed on your system
Usage
Basic Commands
# Show help
cli-anything-blender --help
# Start interactive REPL mode
cli-anything-blender
# Create a new scene project
cli-anything-blender scene new -o scene.blend-cli.json
# Run with JSON output (for agent consumption)
cli-anything-blender --json --project scene.blend-cli.json scene info

Examples
Create a New Project
Create a new Blender scene project file.
cli-anything-blender scene new -o myscene.blend-cli.json
# Or with JSON output for programmatic use
cli-anything-blender --json scene new -o myscene.blend-cli.json
Interactive REPL Session
Start an interactive session with undo/redo support.
cli-anything-blender
# Enter commands interactively
# Use 'help' to see available commands
# Use 'undo' and 'redo' for history navigation
State Management
The CLI maintains session state with:
- Undo/Redo: Up to 50 levels of history
- Project persistence: Save/load project state as JSON
- Session tracking: Track modifications and changes
Output Formats
All commands support dual output modes:
- Human-readable (default): Tables, colors, formatted text
- Machine-readable (
--jsonflag): Structured JSON for agent consumption
# Human output
cli-anything-blender --project scene.blend-cli.json scene info
# JSON output for agents
cli-anything-blender --json --project scene.blend-cli.json scene info
Preview Workflow
Use Blender previews when the agent needs truthful visual checkpoints:
# List preview recipes
cli-anything-blender --project scene.blend-cli.json preview recipes
# Capture a real preview bundle
cli-anything-blender --json --project scene.blend-cli.json preview capture --recipe quick
# Start a live preview loop
cli-anything-blender --json --project scene.blend-cli.json preview live start --recipe quick --mode poll --source-poll-ms 500
# Query current live head without rendering
cli-anything-blender --json --project scene.blend-cli.json preview live status --recipe quick
For agents, preview capture --json returns bundle metadata plus artifact file
paths. preview live status --json returns session metadata plus a compact
trajectory_summary.
For AI Agents
When using this CLI programmatically:
- Always use
--jsonflag for parseable output - Check return codes - 0 for success, non-zero for errors
- Parse stderr for error messages on failure
- MANDATORY: Use absolute paths for all file operations (rendering, project files). Relative paths are prone to failure in background execution.
- Use
preview captureorpreview live ...for visual verification instead of inferring scene quality from JSON alone - Read returned artifact paths such as
hero.pngandworkbench.png; the JSON payload references files, it does not inline image bytes - Treat
_bundle_diras one snapshot only; for stable live history, use_session_dirplus_trajectory_path - Use
cli-hub previews ...only to inspect/open existing previews; preview generation itself always happens throughcli-anything-blender preview ...
