Based on SOC occupation classification
Blender reusable light rigs, HDRI/world setup and rotation animation, light grouping, and render-view controls
Blender object manipulation — create, delete, move, rotate, scale and duplicate objects
Blender rigid body, soft body, cloth, collision, force fields, particle systems, constraints, and simulation cache tools
Set up dcc-mcp-blender for an agent or operator: install Blender Python dependencies with Blender's bundled interpreter, generate MCP host configuration, guide the user through enabling the Blender add-on, and run a first live-tool smoke prompt.
Blender rendering — render scenes, run observable background animation jobs, capture viewport images, and configure output
Blender scene assembly — merge .blend files, append/link data blocks, manage view layers and external references

Blender driver and expression skill. Use it to:
add_driver) with types
SCRIPTED, AVERAGE, SUM, MIN, MAX.set_driver_expression).add_driver_variable) and remove
(remove_driver_variable) the named variables a scripted expression can
reference.list_drivers).evaluate_driver_expression).remove_driver).This skill maps roughly to Maya's Expression Editor and Set Driven Key
workflow. Use blender-animation for plain keyframes and blender-rigging for
bone/constraint setups.
