# Next AI Draw.io

This MCP server lets an agent build draw.io diagrams from project files and show them on a browser canvas you can edit. Useful when you and the agent share diagram work.

## What it does

The agent uses its own tools to read project code and documents, then creates a diagram on a draw.io canvas in your browser. You can edit the canvas yourself, and the server reads those changes before the agent makes another edit. Existing `.drawio` and `.drawio.svg` files can be loaded; diagrams can be saved as `.drawio`, `.png`, `.svg`, or `.drawio.svg`.

Agent changes are briefly marked on the canvas, and Ctrl+Z reverts them. The server can inspect a diagram screenshot for overlaps and restore earlier versions. Add your own drawing guidance in `~/.next-ai-drawio/instructions.md`. It runs through `npx`, with the draw.io editor bundled in the package, and needs an MCP-capable client. Codex asks for approval before tools that modify a diagram run.

## Requirements
- Needs: Node.js (commands run via npx)

## When to use it
- Draw a project architecture from its code and documents
- Load and revise an existing `.drawio` diagram
- Ask the agent to change shapes selected on the canvas
- Inspect a diagram screenshot and fix overlaps
- Export a diagram as `.png` or `.svg`

## Example prompts
- Read this project and draw its architecture on the draw.io canvas.
- Open `architecture.drawio` and rearrange the selected shapes.
- Check a screenshot of the diagram and fix overlapping elements.
