Architecture diagrams, flowcharts, sketches — generated from a single chat message. Whiteboard MCP gives AI a real canvas to think on.
Requires Node.js 18+ (for npx). Most developers already have this.

Rectangles, ellipses, diamonds, arrows, freehand paths, text, images. Everything you'd expect from a real whiteboard.
Define nodes and connections. Whiteboard MCP handles layout, spacing, and arrow routing automatically.
A single create_flowchart call generates a complete diagram from a graph definition. No pixel pushing needed.
Export as PNG, SVG, or JSON. The AI can take screenshots to verify its work before moving on.
This isn't a Mermaid diagram generator. It's a live canvas you work back and forth with. Draw alongside the AI, drag things around, ask it to modify what it drew. Full toolbar with manual drawing tools too.
Everything runs on your machine. No cloud, no accounts, no data leaving your system. Just a local MCP server.
Buy once, own forever. No subscriptions.
