Quickstart (CLI)

Get up and running with the cua Agent CLI in 4 simple steps.

Introduction

cua combines Computer (interface) + Agent (AI) for automating desktop apps. The Agent CLI provides a clean terminal interface to control your remote computer using natural language commands.

Create Your First cua Container

Go to trycua.com/signin
Navigate to Dashboard > Containers > Create Instance
Create a Medium, Ubuntu 22 container
Note your container name and API key

Install cua

Install uv

# Use curl to download the script and execute it with sh:
curl -LsSf https://astral.sh/uv/install.sh | sh

# If your system doesn't have curl, you can use wget:
# wget -qO- https://astral.sh/uv/install.sh | sh

# Use irm to download the script and execute it with iex:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Install Python 3.12

uv python install 3.12
# uv will install cua dependencies automatically when you use --with "cua-agent[cli]"

Interactive Setup

If you haven't set up environment variables, the CLI will guide you through the setup:

Container Name: Enter your cua container name (or get one at trycua.com)
CUA API Key: Enter your cua API key
Provider API Key: Enter your AI provider API key (OpenAI, Anthropic, etc.)

Start Chatting

Once connected, you'll see:

💻 Connected to your-container-name (model, agent_loop)
Type 'exit' to quit.

>

You can ask your agent to perform actions like:

"Take a screenshot and tell me what's on the screen"
"Open Firefox and go to github.com"
"Type 'Hello world' into the terminal"
"Close the current window"
"Click on the search button"

For advanced Python usage and GUI interface, see the Quickstart (GUI) and Quickstart for Developers.
