Overview

What is Sandbox Mcp?

Sandbox Mcp is a Model Context Protocol (MCP) server that enables LLMs to run code in secure, isolated Docker containers. It gives LLMs an easy-to-use execution environment that anyone can create and configure through a simple, AI-native MCP server running locally.

How to use Sandbox Mcp?

Download the appropriate binary for your OS from the Releases page, or install via Go (go install github.com/pottekkat/sandbox-mcp/cmd/sandbox-mcp@latest). Initialize with sandbox-mcp --pull and sandbox-mcp --build (Docker must be installed and running). Then configure your MCP host (e.g., Claude Desktop or Cursor IDE) to use the binary with the --stdio argument.
