How to Auto-Generate System Architecture Diagrams from Code (Miro MCP + Claude Code)
Ever tried to explain a complex server architecture and wished you could just... automatically generate the diagrams? In this demo, we show an incredibly powerful tool that does exactly that.
We use a single command (miro-mcp:code_explain_on_board) to point Miro's MCP Server and Claude Code at a local server codebase.
In just a few minutes, the AI analyzes the code and generates four comprehensive, detailed diagrams directly on our Miro board:
- A high-level System Architecture Diagram
- A detailed Request Sequence Diagram
- An "MCP Server Tools" Mind Map
- A Middleware & Authentication Flowchart
This is a game-changer for onboarding new engineers, documenting existing systems, and keeping visual documentation in sync with your code. Watch to see how it works!
