Nintendo Switch files.
Right on your Mac.

PlugOnce lets an AI agent work with your connected Switch by running commands on your Mac. The agent can check storage and free space, list and find files, read your favorite folders, and check transfer progress. PlugOnce handles the actual transfer, so keep the app open.

For example, ask: “Find main.elf in /switch,” “Prepare to send this Mac folder to my favorite folder on Switch,” or “Show the progress of the last transfer.” The agent needs to be able to run local commands and read the guide below.

Getting started

1. Connect Switch over USB, open DBI → Run MTP responder, and connect the detected device in PlugOnce.
2. Open Settings → Agent Access. Enable access and choose the allowed actions and Switch folders. To send files, also allow their source folder on your Mac.
3. Give the agent the Markdown guide below and describe what to find or which files to send and where.

Before a write, PlugOnce prepares a plan showing the files, destination, required space and existing names. Transfers require your confirmation in the app by default. Reading and sending files have separate permissions.

Version 0.6.7 (45) has separate permissions for autonomous transfers of new files and replacement of existing files. Both are off by default. The agent still stays within the folders and actions you allow in Agent Access.

Raycast is a launcher for quick commands on your Mac. The PlugOnce extension opens favorite device folders, sends files selected in Finder, browses storage and searches your Switch. You can create a Quicklink for a favorite folder and assign it a hotkey in Raycast.

Open Favorites shows the favorites you added in PlugOnce. Send Files to Switch accepts files and folders from Finder or a file picker. Browse and Search Device finds files, while Transfer Operations shows progress, speed and time remaining and lets you cancel your transfer. Device Status shows the connection, storage capacity and free space.

If your Raycast supports AI tools, you can request these actions in plain language, such as “Open my favorite folder” or “Prepare to send the selected files to Switch.” Regular commands work without Raycast AI.

Getting started

1. Install Raycast and import the separate PlugOnce extension using the guide below. You need a local copy of the extension; a public download is not available yet.
2. Keep PlugOnce open, connect Switch through DBI, and allow the required folders and actions in Settings → Agent Access. To transfer files, also allow their Mac source folders.
3. Run a Raycast command and choose the files and destination. Review the transfer plan and confirm the write in PlugOnce when confirmation is required.

The extension uses Agent Access permissions and the PlugOnce transfer queue. It does not grant itself new permissions. PlugOnce performs the transfers, so its commands are unavailable when the app is closed.

The app version is 0.6.8; the build number is 46. Beta means a version for testing. Include both numbers when reporting a problem on the forum.

Notarization is Apple's automated check for known malicious software. This build is not notarized, so macOS may block it when you first open it and say that it cannot verify the app. Apple's guide explains this alert.
