What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

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
