🚀@Microsoft Execution Containers (MXC) provide policy-driven, sandboxed execution across Windows, Linux, and macOS. Box Mount runs inside that sandbox and maps a Box folder to a standard POSIX path, with two-way sync and Box permissions and governance applying automatically. In this demo, the agent reconciles fictional invoices, purchase orders, and payments using deterministic tools. It identifies six exceptions including duplicate records, a missing PO, an over-limit invoice, and unpaid invoices. The finished Markdown review and Excel exception workbook sync back to Box through Box Mount. MXC is the isolated execution layer, and Box Mount is the governed content layer. The result lands in Box, ready for human review. Demo ↓

Microsoft MXC gives AI agents a controlled environment to run code, with policies that define which files they can read, where they can write, and what they can access. This demo shows MXC running natively on @Windows, connected to governed business content in Box through Box Drive. Only approved files are staged into MXC before the agent runs. Box Drive makes the content accessible through the desktop filesystem. When the work is finished, results return to Box for team review. MXC enforces what the agent can do. Box provides secure, governed content management and brings the output back into the team's workflow. Together, they connect useful agent work with enterprise controls. Demo below ↓
