Show HN: Excalidraw Architect MCP for AI Based IDEs

Hey Folks, I've been building an MCP server that generates beautiful Excalidraw architecture diagrams fully auto-laid-out, no manual positioning. It's open source, works with any AI IDE (Cursor, Windsurf, etc.). I wanted to share it early because the core layout engine is solid and already producing clean diagrams. What Problem Am I Solving? AI IDEs generate architecture diagrams as Mermaid or ASCII art. When they attempt Excalidraw, they hallucinate coordinates and boxes overlap, arrows cross through nodes, and you spend time fixing the diagram than drawing it yourself.
