WHAT IT DOES

What timeline_grab_still does on DaVinci Resolve MCP

AI agents use timeline_grab_still to create or update resources in DaVinci Resolve MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DaVinci Resolve MCP environment.

RISK

Why timeline_grab_still is rated Medium

This tool captures and saves a still image from the current timeline frame, creating a new asset/file. This is a Write operation as it creates new data (a still image) that can be stored in the media pool or gallery. It is reversible (the still can be deleted), so it doesn't qualify as Destructive. Misuse could clutter the project with unwanted stills but has limited blast radius.
