Show HN: Composer – AI architect / MCP for software architecture diagrams

Hi everyone!<p>I built Composer, which is a tool turns your ideas into architecture diagrams. You can also use MCP to turn your EXISTING codebase into a visual diagram!<p>It connects to all possible tools using MCP (Claude Code, Codex, OpenCode, etc.)<p>The goal was to make system design easier and to be able to draw out what I wanted to make before I started &#x2F; to explain to others.<p>Its currently live at usecomposer.com and free!<p>I’d love feedback on whether it feels useful for real pro
