timeline_scrubber · GSAP MCP Server MCP: Risk & Policy

WHAT IT DOES

What timeline_scrubber does on GSAP MCP Server

AI agents invoke timeline_scrubber to trigger actions in GSAP MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why timeline_scrubber needs a policy

This tool controls the scrubbing/dragging of an animation timeline, which constitutes executing an interactive operation that manipulates animation playback state. It's not purely reading data nor creating/modifying stored data, but rather triggering an external operation (timeline control). The description is minimal (Chinese only), which lowers confidence slightly.

From the tool's definition '时间轴拖拽控制' translates to 'timeline scrubbing/drag control' - triggers interactive control of animation timeline playback
