Programmatic canvas toolkit for creating, editing, and refining Excalidraw diagrams via MCP tools with real-time canvas sync. Use when an agent needs to (1) draw or lay out diagrams on a live canvas, (2) iteratively refine diagrams using describe_scene and get_canvas_screenshot to see its own work, (3) export/import .excalidraw files or PNG/SVG images, (4) save/restore canvas snapshots, (5) convert Mermaid to Excalidraw, or (6) perform element-level CRUD, alignment, distribution, grouping, duplication, and locking. Requires a running canvas server (EXPRESS_SERVER_URL, default http://localhost:3000).
Draw a simple diagram on the live Excalidraw canvas.
High-intent search queries and answers about installing and using this skill.
You can automate Excalidraw diagram creation and editing programmatically through MCP and REST APIs that sync changes to a live canvas server in real time for iterative refinement.
Yes, you can export Excalidraw diagrams to PNG, SVG, and native .excalidraw file formats via API commands, enabling automated diagram workflows for sharing and downstream processing.
You can convert Mermaid diagrams to Excalidraw format by sending Mermaid syntax through the MCP tools, which renders the equivalent elements onto the live Excalidraw canvas for further editing.
Yes, you need a running canvas server accessible at the EXPRESS_SERVER_URL endpoint, defaulting to http://localhost:3000, to execute MCP commands and synchronize diagram changes in real time.
An agent visually refines diagrams using the describe_scene and get_canvas_screenshot tools to inspect its own work on the live Excalidraw canvas, enabling iterative layout and element adjustments.
Automation is limited by the requirement of a continuously running canvas server at the specified EXPRESS_SERVER_URL endpoint, meaning the APIs cannot execute commands or sync changes in offline or serverless environments.
