Create and edit editable Excalidraw diagrams in Canvas Notebook through the Scene-Service tools. Use for diagrams, flows, sketches, architecture maps, visual explanations, or requested .excalidraw documents.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Excalidraw Diagram

Create and edit a managed `.excalidraw` document through Canvas's Scene-Service. PostgreSQL holds the authoritative scene; the portable file is a checkpoint. These tools work without an open editor in personal, organization, team, and project workspaces.

## Required tools and boundaries

Use `create_excalidraw_scene`, `get_excalidraw_scene`, and `edit_excalidraw_scene`. If a required tool is missing or disabled, report an activation or compatibility error and ask the user to enable it or use a compatible Canvas backend. A missing PostgreSQL provider is an error. Do not substitute another write path.

Never create or change `.excalidraw` bytes through generic write/edit/patch tools, direct workspace filesystem access, shell, Python, Node, copy-overwrite, or snapshot saves. Never submit a complete scene replacement. The bundled Python validator only reads JSON; it does not create files or publish a scene.

How to install

The exact contents, by fingerprint

mdr add canvascoding/canvas-notebook/excalidraw-diagram@sha256:4a75e723a0291868

The line at the top of this page pins the label v1.4.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
