Excalidraw / Mermaid.js Clipboard Monitor and Replacer - This library is a collection of scripts that monitor the clipboard and replace any copied Excalidraw node containing a Mermaid.js diagram with the diagram rendered with Mermaid.js and converted to a format that can be pasted back into Excalidraw using Excalidraw's native drawing format.

Converts Mermaid diagrams into Excalidraw diagrams, serves them locally, and opens the result in your browser. Includes an MCP server for AI assistants.
