Excalidraw MCP is a backend oriented Model Context Protocol (MCP) server that enables AI agents to create, inspect, edit, diagnose, and export native [Excalidraw](https://excalidraw.com) diagrams over standard `stdio`.

Unlike browser automation wrappers, Excalidraw MCP operates directly on scene graphs and element trees in memory. AI coding agents can construct complex architectures, generate flowcharts from Mermaid syntax, inspect element hierarchies, and apply deterministic layout repairs without requiring a running web browser or graphical interface.

Diagrams are serialized in native Excalidraw Schema v2 format, ensuring immediate compatibility with excalidraw.com, standard Excalidraw desktop extensions, and headless image export pipelines.
