collect_scale_timeline · Vibe Stack MCP: Risk & Policy

WHAT IT DOES

What collect_scale_timeline does on Vibe Stack MCP

AI agents invoke collect_scale_timeline to trigger actions in Vibe Stack MCP. 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.
