Introducing Sandbox Computer Use for Mastra Agents (Mastra)
Mastra agents can now drive a sandboxed Linux desktop through E2B Desktop or Daytona, with 11 computer tools for browsing, forms, downloads, screenshots, and terminal programs. A SandboxComputer interface exposes screen size, cursor position, and a stream URL so you can watch the agent work.
In plain words
- Mastra released a feature that lets artificial intelligence control a separate desktop running the Linux operating system.
- It can browse websites, complete forms, download files, take screenshots, and run programs through a text-based command window.
- Builders can see the screen, track the pointer, and watch a live view of the work.
- This gives software builders broader automation while keeping the artificial intelligence away from their main computers.
