Description

Archy is an MCP server that creates a wide variety of Mermaid diagrams (flowcharts, class diagrams, sequence diagrams, C4, git graphs, etc.) from plain text descriptions or by analyzing GitHub repositories. It includes AI-enhanced options via OpenRouter/LangChain (optional API key), repository evolution tracking, and image export to PNG/SVG/PDF. Archy is designed to be integrated into MCP clients (VS Code, Claude) and supports in-memory git analysis and configurable export options to streamline diagram generation and documentation workflows.
