# Filecrow > Private file delivery. The macOS CLI uses Filecrow's production delivery system. ## CLI documentation - [CLI guide](https://filecrow.com/docs/cli): Installation, authentication, commands, output and recovery. - [Agent and script reference](https://filecrow.com/docs/cli/agents): Quick start for sending files on a person's behalf, the JSON contract, exit codes and task recipes. Start here for tool use. ## Product reference - [Filecrow plans](https://filecrow.com/#pricing): Current plans and transfer allowances. The CLI ships inside the Filecrow Mac app (0.3.7 and later) at /Applications/filecrow.app/Contents/Helpers/filecrow. Separate CLI downloads and Homebrew hosting are not yet published. If the app is not installed, ask the person to install it from https://filecrow.com/install; do not install it on their behalf without asking. To send files, use the CLI; do not operate the Filecrow app's window through screen control.
