CRIT STUDIO
Launch Workspace
WebMCP Canvas Engine v1.0

Give your AI agent hands, not just words.

Crit Studio exposes design canvases as WebMCP tools so AI agents can inspect coordinates, flag visual flaws, resize touch targets, and rebalance layouts live on screen.

Open Interactive WorkspaceSee How It Works
Three Simple Steps to Review Any Canvas
1

Build a Mockup

Place headings, text, buttons, and blocks on the canvas or seed an existing layout.

2

Talk to the AI

AI calls getCanvasState to inspect exact element coordinates and font properties.

3

Watch Live Execution

Agent stamps redline flags, resizes touch targets, and aligns spacing in real time.

Why WebMCP? Spatial Tools vs Passive Chat
TRADITIONAL CHAT / VISION

Passive Text Descriptions

AI generates verbose text advice. You manually interpret and tweak coordinates yourself.

Ambiguous feedback ("make button bigger")
Vision models approximate clicks unreliably
Zero direct execution on the DOM or canvas
WEBMCP SPATIAL TOOLS

Direct Canvas Execution

AI calls structured browser tools, mutating element coordinates and spacing live.

Structured tools: flagIssue, resizeElement
Exact coordinate inspection via getCanvasState
Changes reflow with sub-pixel precision
