figma_run · Figma Unified MCP: Risk & Policy

WHAT IT DOES

What figma_run does on Figma Unified

AI agents invoke figma_run to trigger actions in Figma Unified. 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.
