pi-ssh-paste-image

Overview

Paste clipboard text, images, or selected local files from your local machine into Pi running on a remote Unix-like host over SSH. The package contains both a Pi extension and the pi-ssh-paste-image CLI.

Requirements

The local machine needs Node.js 20+ and an OpenSSH ssh client. On Linux, clipboard access uses wl-paste on Wayland or xclip/xsel on X11. On macOS, text uses pbpaste and images use pngpaste. On Windows, clipboard text uses PowerShell Get-Clipboard; image clipboard support is not currently implemented on Windows.

The remote machine needs Pi, a POSIX-compatible shell, rm, Unix-domain sockets, and an SSH server that permits stream-local forwarding. The normal ssh command creates a reverse Unix socket on the remote host. The remote socket is requested with mode 0600 through StreamLocalBindMask=0177.

On Linux and macOS, the local clipboard daemon listens on a Unix socket inside a private temporary directory. On Windows, it listens only on an ephemeral 127.0.0.1 TCP port because Node.js does not expose filesystem Unix sockets there. In both cases, requests also require a random per-session token. The daemon reads the clipboard only after you invoke /paste, /ssh-paste, or the configured shortcut.

Binary clipboard data is written on the remote machine. The default output directory is /tmp/pi-ssh-paste-image, created with mode 0700; saved files are created with mode 0600. Clipboard text is inserted directly into the Pi editor instead of being written to disk.

Installation

Install the CLI on the local machine:

npm install --global @yukikisaku/pi-ssh-paste-image

Install the Pi extension on the remote machine where Pi runs:

pi install npm:@yukikisaku/pi-ssh-paste-image

Usage

Check the local requirements first:

pi-ssh-paste-image doctor

Start Pi through the SSH wrapper:

pi-ssh-paste-image ssh user@host -- pi

The CLI starts the local clipboard daemon, creates a reverse socket on the remote host, exports the required PI_PASTE_* values for the remote Pi process, and removes the remote socket when the SSH session exits. While Pi is running, use /paste, /ssh-paste, or Alt+Shift+V to request the current local clipboard content.

Useful SSH options are --output-dir DIR, --max-bytes SIZE, --remote-socket PATH, and repeatable --ssh-option VALUE. The default transfer limit is 20 MiB. Additional SSH options are passed directly to the local ssh executable.

Configuration

Configure sshPasteImage in global Pi settings or in a trusted project's .pi/settings.json. Supported keys are shortcut, outputDir, socketPath, token, maxBytes, and timeoutMs.

Environment overrides use PI_PASTE_SOCK, PI_PASTE_TOKEN, PI_PASTE_OUTPUT_DIR, PI_PASTE_MAX_BYTES, and PI_PASTE_TIMEOUT_MS. The normal pi-ssh-paste-image ssh ... flow generates the socket path and random token automatically, so you normally do not need to set them yourself.

Uninstallation

Remove the local CLI:

npm uninstall --global @yukikisaku/pi-ssh-paste-image

Remove the remote Pi package:

pi uninstall npm:@yukikisaku/pi-ssh-paste-image

Remove package-specific Pi configuration if you no longer need it. Files previously saved in the configured output directory are not deleted automatically.
