Microsoft launches open-source AI agent sandbox, MXC

By PulseAugur Editorial · [1 sources] ·

Microsoft has released Microsoft Execution Containers (MXC) as a generally available open-source project. MXC provides a policy-driven containment framework for running untrusted AI workloads, such as code generation or script execution, within secure boundaries. It unifies various container backends across Windows, Linux, and macOS, allowing developers to specify granular policies for filesystem access, network connectivity, and UI interaction. The tool also includes diagnostic and auditing modes to help fine-tune policies for optimal security and functionality. AI

IMPACT Enhances security for AI agents by providing granular control over their execution environment and resource access.
