draw2agent ✏️

Draw on your website. Your AI agent sees it.

draw2agent is an MCP server that lets you draw annotations directly on top of your local dev page. When you submit, your IDE agent receives a screenshot, structured DOM data, and annotation context to make precise code edits.

👉 Try it out at: draw2agent.vercel.app

Demo

Quick Start

1. Add to your IDE (one-time)

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "draw2agent": {
      "command": "npx",
      "args": ["-y", "draw2agent@latest"]
    }
  }
}

2. Use it

Tell your agent:

"Use draw2agent to fix the navbar"

1. 🌐 Agent opens your browser with drawing tools on your page
2. ✏️ Draw circles, arrows, text directly on your website
3. 📸 Click Submit
4. 🤖 Agent reads the visual context and applies code changes

How It Works

Your Dev Page (proxied)
├── Your original page content
└── Excalidraw overlay (transparent, on top)
    ├── Draw mode: annotate directly on the page
    ├── Select mode: interact with the page normally (Esc)
    └── Submit: screenshot + DOM + annotations → agent

Tools

The MCP server exposes the following tools:

| Tool | Description | |---|---| | launch_canvas | Opens your dev page with the drawing overlay | | launch_ipad_canvas | Creates a tunnel and returns a QR code for remote drawing from iPad/mobile | | launch_scratch | Opens a standalone Excalidraw whiteboard for freehand sketching | | get_drawing_state | Returns screenshot, DOM nodes, and annotations for the current state |

launch_canvas

The core tool — proxies your localhost dev server and injects an Excalidraw overlay. Draw annotations directly on your running app, then submit to send visual context to your agent. The tool blocks until you submit.

launch_ipad_canvas

Same as launch_canvas, but exposes the proxy over the internet via a secure tunnel. Automatically opens a new browser tab on your computer with a QR code. Scan it from your iPad or phone to draw annotations with touch. Perfect for whiteboard-style feedback sessions.

launch_scratch

Opens a blank Excalidraw whiteboard — no target URL needed. Sketch UI mockups, wireframes, or diagrams from scratch. Your agent receives the drawing and implements the design.

get_drawing_state

Returns the last captured drawing state (screenshot, DOM nodes, annotations) without launching a new session. Useful for re-fetching context.
