TL;DR I spent a full day trying to automatically generate professional architecture diagrams for a 7-node k3s homelab. Figma’s MCP integration was perfect but requires a paid subscription. I tried Excalidraw (JSON generation + Kroki rendering), Mermaid, and finally landed on raw SVG generation in Python.
