Show HN: Composer – Diagram Your Codebase with MCP

https://www.usecomposer.com/
3•olivergrabner•3h ago
I've been working on Composer 2.0 (usecomposer.com), a tool that connects to your AI coding agents (Claude Code, Cursor, Copilot, Windsurf) via MCP and generates full architecture diagrams from your codebase.

You can also describe what you want to build in plain English and an AI architect designs the system with you!

Would love feedback on where it's useful and where it breaks down.
