ruinivist 0d0d4b8a85 fix: reload drawing when edited externally by MCP
Adds an active polling and reload mechanism. It tracks the `updatedAt` timestamp of the current drawing and polls `refreshList` every 5 seconds. If the server's drawing is newer, it clears pending autosaves and reloads the drawing to reflect the external changes.

Also tracks when a title save is in progress to avoid reloading when the current user renamed the drawing.

excali-box

Private self-hosted Excalidraw with Bun, Caddy, and SQLite.

This is bare wrapper around the excalidraw packages that adds autosave and disk-persistence. No auth to keep things simple - you either run in a private network or put it behind Caddy auth or similar solutions.

Pull from GHCR and run

Images are published to:

ghcr.io/ruinivist/excalidraw-box:<version>

docker pull ghcr.io/ruinivist/excalidraw-box:latest
docker run --rm -p 127.0.0.1:3000:80 -e PUBLIC_BASE_URL=http://localhost:3000 -v "$PWD/excali-box-data:/data" ghcr.io/ruinivist/excalidraw-box:latest

Run locally

bun install
bun run dev

Open http://localhost:3000.

Test

bun run test
bun run typecheck

Build the image

docker build -t excali .
docker run --rm -p 127.0.0.1:3000:80 -e PUBLIC_BASE_URL=http://localhost:3000 -v "$PWD/excali-box-data:/data" excali

This will make the data persistent in the excali-box-data folder in the current directory, with Caddy serving the browser build on localhost:3000. PUBLIC_BASE_URL is required so MCP tools can return drawing URLs with the public browser origin. You would want it to be the same url you use to access the app in the browser - in case you reverse proxy or use a tailscale alias etc.
