Excalidraw Architect

Excalidraw Architect is a Model Context Protocol (MCP) server that enables AI-driven, auto-layout system architecture diagrams from natural language or codebase analysis, streamlining onboarding, documentation, and design for developers and engineering teams. It separates diagram structure from layout, automatically styles components based on widely-used technologies, and allows iterative, conversational editing. The tool supports a persistent, version-controlled architecture knowledge graph and offers full offline usage in supported IDEs like Cursor and Windsurf.
