Excalidraw Architect MCP

An MCP server that generates beautiful, auto-laid-out Excalidraw diagrams from natural language descriptions. It supports 25 diagram types including architecture, flowcharts, and Gantt charts, using a pure-Python port of roughjs for hand-drawn styling. It runs offline without API keys in Cursor, Claude Code, and Windsurf, separating structure from layout to prevent hallucinated coordinates.
