What does CLI mean?
CLI means Command Line Interface: a text-based way to interact with a computer by typing commands instead of clicking buttons.
It’s commonly used for system administration, software development, and automation because it can be fast and precise.
Most people use a mouse to click on icons. This is called a GUI (Graphical User Interface). While a GUI is pretty, a CLI is much more powerful for specific tasks:
- Save time: You can move, rename, or delete thousands of files with one line of text. Clicking them one by one would take hours.
- Automate tasks: You can write a list of commands once and tell the computer to run them every day.
- Talk to servers: Most computers that power the internet (servers) do not have screens or mice. You must use a CLI to manage them.
- Use less power: Because there are no heavy graphics, the CLI makes your computer run faster and uses less battery.
- Developer tools: Most modern coding tools only work inside a CLI.

What is a CLI vs API?
A CLI is a way to interact with software by typing commands into a terminal, while an API is a way for programs to communicate with each other through defined interfaces.
Simple difference:
- CLI: designed for humans to type commands and get immediate results, like running git status or docker ps.
- API: designed for software to call functions or send requests programmatically, often for automation or integration.
What is MCP (Model Context Protocol) and why does it matter for IT support automation?
MCP, or Model Context Protocol, is a standard from Anthropic that gives AI agents a single, consistent way to read and write data across your existing tools, making it practical to automate multi-step IT support processes without building custom integrations from scratch.
