RegScale-CLI Server and API Wrapper


This document provides a guide to running the RegScale-CLI in Server mode which provides both a GUI for uploading certain files and REST API wrapper to interact with the CLI by using HTTP requests instead of command-line interfaces.

What is it?

The RegScale-CLI Server provides:

  • a REST API service for the RegScale-CLI through which any command that can be executed via the regscale CLI application can be accessed either via a GET command (if no arguments are expected) or a POST command (if arguments are expected)
  • a GUI for uploading STIG files and other files to the platform for users who prefer a GUI over the commandline.

Why would you use it?

Operations using the RegScale-CLI can be reduced to GET and POST requests to your local machine or to a machine running the API Wrapper. This allows users to remotely call RegScale-CLI commands with an HTTP request rather than manually running the commands. The primary use case is for scheduling or automating RegScale-CLI commands and provides users with familiarity with REST APIs the ability to control RegScale-CLI via REST API requests through curl, python, Postman, etc.

To access the certain uploads via a browser interface.


RegScale-CLI must be installed with the server extra to add the additional required libraries. Install the RegScale-CLI "server" package using pip:

pip install "regscale-cli[server]"


Use the following command to start up the CLI-Server.


The following will appear in the terminal indicating the CLI is operating in Server mode using Flask.

Use the following command to start up the CLI-Server running in the background on Unix.

regscale-rest &

To run CLI-Server persistently on a remote Unix host, open up the desired port on the Unix host and start the RegScale-Server in the background (or through your preferred mechanism).

# Logged into remote unix host
# Open port 8000 on unix host
regscale-rest &


When running in a directory initialized for use with RegScale-CLI, i.e. the presence of a configured or configurable init.yaml,

  • REST API interface: The wrapper provides a REST API interface to the Click-based Python CLI, allowing for interaction via standard HTTP methods like POST and GET.
  • Parameter passing: Parameters for the commands can be passed in the body of a POST request. This allows for dynamic and flexible command execution.
  • No parameter GET requests: For commands that do not require parameters, GET requests can be used.


By default, the Flask REST API is started via regscale-rest and all commands are endpoints. For example, below is the output of regscale aboutrun via the API interface using a curl command.

> curl --silent localhost:5555/about | jq -r .output

POST requests

POST requests can be used to pass parameters to a command. Here's an example:

import requests

data = {"param1": "value1", "param2": "value2"}
response = requests.post("http://<url>/command", data=data)
