OpenArchFlow

What it does

OpenArchFlow connects AI models to AWS service knowledge through the Model Context Protocol, enabling cloud architects and DevOps engineers to generate professional, interactive AWS architecture diagrams from plain-language descriptions. It combines AWS MCP for up-to-date service recommendations with either Google Gemini or a local WebLLM engine for diagram generation — all running client-side with zero data collection.

Tools

• generate_diagram — Create architecture diagrams from natural language descriptions
• modify_diagram — Incrementally update or append to existing diagrams
• generate_specification — Produce Markdown documentation from diagrams including best practices, cost estimates, and security reviews
• aws_services — Query AWS Documentation MCP for current service details and recommendations
• diagram_chat — Discuss architecture, pricing, and security with an AI assistant
