## What it is
An MCP server, CLI, and agent skill that gives AI coding agents a live, stateful Excalidraw canvas they can draw on, inspect via screenshots, and export as .excalidraw files. It exposes 26 tools over stdio (MCP), a CLI, and a REST/WebSocket-backed canvas server for real-time diagram creation and editing.

## Use cases
- generate architecture diagrams with an AI agent
- create flowcharts programmatically from a prompt
- convert mermaid diagrams to excalidraw
- let a coding agent draw and refine diagrams on a live canvas
- export editable excalidraw files into a repository
- connect claude desktop or cursor to a diagramming tool via mcp

## When to choose
- you use Claude Code, Cursor, Codex CLI, or another MCP client and want AI-generated editable diagrams
- you need a persistent, stateful canvas the agent can revisit and refine rather than one-shot images
- you want to commit .excalidraw diagram files alongside your code
- you want a local, MIT-licensed diagramming toolkit with no API keys

## When to avoid
- you only need static diagram images without editing or agent interaction
- you cannot run Node.js 20+ locally
- you need diagramming fully offline without a browser canvas for mermaid conversion
- you want a simple diagram-as-code tool without an AI agent
