// How it works
Excalidraw WebMCP
— how it works
The idea
Every web page has a small set of actions — create, read, update, delete. We expose these as tool calls so an AI can control the page in real time.
You
Type what you want in plain English. The AI figures out which tools to call and in what order.
Tools
This demo exposes:
That's it
Just four operations and the ability to manipulate the page — that's all the AI needs. No screenshots, no pixel-clicking. Real functions called directly.
Credits
Each session uses a real LLM. You get $1 free credit to start. Roughly $0.04–$0.15 per session.
