WHAT IT DOES

What set_timeline_item_composite does on DaVinci Resolve MCP

RISK

Why set_timeline_item_composite is rated Medium

This tool modifies video timeline compositing properties, which are reversible changes to a project file. It does not execute arbitrary code or delete data, making it Write rather than Execute or Destructive. The severity is medium because misuse could corrupt editing work or produce unintended visual output, but changes can be undone via standard video editing undo functionality.

From the tool's definition Tool name 'set_timeline_item_composite' and description 'Set composite properties for a timeline item' indicate modification of existing timeline item attributes.
