excalidraw-diagram

Create real Excalidraw elements with one editable source of truth. Read REFERENCE.md for Mermaid conversion, direct elements, and visual language.

Canvas

All commands use the pinned CLI:

export EXPRESS_SERVER_URL="http://127.0.0.1:${CONDUCTOR_PORT:-3000}"
bunx mcp-excalidraw-server@1.1.0 <command>

Use bunx cache; never add it to the consumer repo. Run start, open the URL in an isolated browser, keep it open, and require status to show a client. If isolation is unavailable, ask the user to open the URL once.
