Overview

What is Superserve Sandbox?

Superserve Sandbox is an MCP server that lets any MCP client create and control isolated cloud sandboxes. Each sandbox is a Firecracker microVM that boots in seconds, and agents can run shell commands, read and write files, install dependencies, and expose running servers as public preview URLs. Secrets are brokered by the platform so credentials never pass through the model, and outbound network access is controllable per sandbox.

How to use Superserve Sandbox?

Run it locally with npx -y @superserve/mcp or connect to the hosted endpoint at mcp.superserve.ai – both require your Superserve API key for authentication. Works with Claude, Cursor, VS Code, Windsurf, and Codex.
