Learn how to use Amazon Q with Model Context Protocol (MCP) to automatically generate AWS architecture diagrams using natural language prompts. The guide walks through installation and configuration of Amazon Q, GraphViz, and MCP servers, then demonstrates creating three types of diagrams: web application architecture with ALB and RDS, three-tier architecture with ECS and Aurora, and data processing pipelines with Kinesis and Lambda. While the generated diagrams serve as solid starting points requiring human refinement, this approach shows how AI assistants can streamline cloud architecture documentation workflows.
