About

What is microsandbox?

Microsandbox is an open-source tool designed to provide secure, local, and programmable sandboxes for AI agents. It allows users to spin up lightweight virtual machines (VMs) in milliseconds directly from SDKs, running locally on their machine without requiring a server setup or lingering daemon. Key features include hardware-level isolation using microVM technology, instant startup times averaging under 100 milliseconds, and embeddability within code. It supports OCI compatible container images and allows sandboxes to run in detached mode for long-lived sessions. Microsandbox also enables AI agents to create and manage their own sandboxes through Agent Skills and an MCP server, offering unexploitable secret keys that never enter the VM.

Best used for

Ideal for developers and data scientists who need to securely execute untrusted code, provide isolated environments for AI agents, and manage virtual machines directly within their applications. Especially valuable for building robust AI systems that require secure and programmable execution environments.

FAQs

What are the system requirements for Microsandbox?

Microsandbox requires Linux with KVM enabled or macOS with Apple Silicon. It is currently in beta, so users should expect potential breaking changes, missing features, and rough edges during development.

How does Microsandbox provide security for AI agents?

Microsandbox offers hardware-level isolation through microVM technology and ensures secrets cannot leak by never entering the VM. This provides a secure environment for executing potentially untrusted code and protecting sensitive information.

Can Microsandbox be integrated with existing AI agent frameworks?

Yes, Microsandbox provides Agent Skills to teach AI coding agents how to use it, compatible with tools like Claude Code, Cursor, and GitHub Copilot. It also offers an MCP server for connecting any MCP-compatible agent, providing structured tool calls for sandbox management.
