A reusable Python SDK for controlling a computer-using agent in a virtual desktop.

CUA Agent SDK

A reusable, pip-installable Python SDK for controlling a computer-using agent in a virtual desktop (e.g., Docker, VNC, or any custom environment) using OpenAI CUA models. The SDK is fully configurable, class-based, and easy to integrate into any Python project.

🛠️ Usage

from cua_sdk import ComputerAgent

agent = ComputerAgent(
    openai_api_key="sk-...",
    llm_model="computer-use-preview",
    docker_container_name="cua-image",
    docker_display=":99",
    sleep_time=0.2,
    screen_width=800,
    screen_height=600,
    screenshot_format="jpeg",
    screenshot_detail="low",
    prompt_path="prompt.txt",
    # ...any other config
)

agent.start()
agent.send_prompt("Apply to this job: https://company.com/apply/123")
agent.change_config(llm_model="gpt-4.1-mini", sleep_time=0.1)
screenshot = agent.get_screenshot()
agent.reset_history()
agent.stop()

• All parameters can be set via constructor, environment variables, or config defaults.
• The agent is fully modular and can be used in any Python project.

📝 Notes

• The SDK does not require Docker or any specific environment—just pass the right config for your use case.
• Example Dockerfiles and scripts are provided in /docker for convenience, but are not required for SDK use.
• You can use your own prompt templates, models, and agent configuration.
