Open the live FX Studio creative workbench, optionally on a saved scene. The same view updates as you edit its actual HTML/CSS/JavaScript source with scene_read, scene_write or scene_edit and inspect images with scene_preview. Supports DOM, SVG, Canvas and WebGL through one programmable scene contract. Opening is read-only and does not create an effect or change production defaults. Returns a first-party studio link for hosts without app rendering. Keep this view open through successive edits; only this tool opens the app.

The JSON blocks below are the exact MCP descriptor projections served by Rails for the named profiles at capture time. Security schemes and resource URIs may vary by connected host.
