Excalidraw MCP

Overview

Create and refine diagrams on a live Excalidraw canvas via MCP tools, with helper scripts for export/import workflows.

Quick Start

Ensure the canvas server is reachable at EXPRESS_SERVER_URL (default http://localhost:3000).
Use MCP tools for interactive diagram edits; use scripts/*.cjs for file-ish workflows (export/import/clear/health).
For detailed endpoint/tool reference, read references/cheatsheet.md.
