🎯 Purpose

Terminal Guardian helps you use AI tools in your computer terminal. It checks your commands for risks before they run. This tool stops harmful actions and protects your files. It creates a safe workspace for your AI assistant.

💻 What this tool does

Many AI tools connect to your computer terminal. This allows the AI to change your files or delete data. Terminal Guardian acts as a filter. It watches what the AI tries to do and blocks dangerous commands. It logs every action so you can review what happened later. It also uses a sandbox to trap risky processes.

docker_logsreadRetrieve logs from a Docker container.
docker_psreadList Docker containers with their status, image, and port information.
docker_statsreadGet real-time resource usage statistics for a Docker container.
get_envreadRead environment variables with automatic secret masking. Secrets (tokens, passwords, keys) are shown as masked values like
