OnlyVPN CLI

Platform invocation

Prerequisite: The main client process must be running before vpn-cli / vpn-cli.exe will work. Start onlynet.exe (Windows) or launch OnlyNet inside Onlynet.app (macOS) first; then use the CLI.

All documented subcommands and flags are passed after the CLI name (e.g. Windows: vpn-cli.exe status; macOS: vpn-cli status).

When to use this skill

Apply when automating or documenting the OnlyVPN VPN client through vpn-cli.exe (Windows) or vpn-cli (macOS)—only after the main app (onlynet.exe / OnlyNet) is running. Output is JSON for scripting; parse code, message, and data / error fields.

Install and startup order (before using the CLI)

Windows

1. Download: https://onlyvpn.net/download/client/onlynet_win.exe
2. Run the installer. By default the application installs under C:\Program Files\onlynet.
3. Start the main client first: run onlynet.exe from that directory, for example:

"C:\Program Files\onlynet\onlynet.exe"

Keep this process running; the CLI talks to it.

1. Then run the CLI with vpn-cli.exe plus arguments, for example:

"C:\Program Files\onlynet\vpn-cli.exe" --version

If the installer adds that directory to PATH, you can run onlynet.exe and vpn-cli.exe without full paths.

macOS

1. Download: https://onlyvpn.net/download/client/onlynet_mac.zip
2. Unzip the archive. Locate Onlynet.app in the extracted folder (exact path depends on zip layout). Optionally install the included .dmg and copy Onlynet.app to Applications—either way you need the bundle on disk.
3. Start the main client first (required before vpn-cli works). Standard macOS bundle layout uses Contents/MacOS/ (not a single ContentsMacOS folder):

   open path/to/Onlynet.app

or run the binary directly:

   path/to/Onlynet.app/Contents/MacOS/OnlyNet

If the app lives under Applications, use e.g. /Applications/Onlynet.app/Contents/MacOS/OnlyNet or open -a Onlynet. Leave this process running.

1. Use the vpn-cli binary from the zip (no .exe) with arguments. If it is not on PATH, copy it into a directory on PATH, for example:

   sudo cp path/to/vpn-cli /usr/local/bin/
   sudo chmod +x /usr/local/bin/vpn-cli

1. Confirm (with OnlyNet already running): vpn-cli --version

Response shape (success)

Successful commands return JSON with code, message, and usually data. Example shapes are in reference.md.

Note: Product docs may state success as code: 0; examples below often use code: 200. Treat success per your installed build (either 0 or 200 as documented) and treat other values as failure; always read message and optional error.

Response shape (failure)

On failure, responses include code (not success), message, and an error object with type, details, optional hint, plus optional request_id and ts (UTC ISO8601). See reference.md for common error codes.

Commands (quick reference)

Replace vpn-cli below with vpn-cli.exe on Windows (and quote the full path if needed, e.g. "C:\Program Files\onlynet\vpn-cli.exe").

Connect behavior (defaults)

• With connect sub ... node ...: optional --best may apply where supported.
• Without sub: uses last used or first subscription.
• Without node or if the name is missing: uses first node in scope.
• Without both: connects to the first node.

Agent guidance

• Start the main client before any CLI: on Windows run onlynet.exe from the install directory (default C:\Program Files\onlynet\); on macOS launch Onlynet.app or run Onlynet.app/Contents/MacOS/OnlyNet from the unzip (or installed) location.
• Then run the real CLI: Windows — vpn-cli.exe; macOS — vpn-cli. Do not invent a separate HTTP API.
• If CLI commands fail or hang, verify onlynet.exe / OnlyNet is still running.
• Parse JSON stdout; handle both example success codes (200 vs 0) if users report differences between builds.
• For full response examples and error catalog, read reference.md.
