Automatic dependency detection and installation (pip, npm, go get).
Real-time output and log streaming from containers.
Background mode for long-running services.
Volume mounting for project execution.
Resource-limited, clean container cleanup after execution.

Use cases of Code Sandbox MCP

Run untrusted code snippets safely without host system exposure.

Frequently asked questions

What languages are supported?

Python, Go, Node.js (including TypeScript/JSX via built-in Node.js support) are supported.

How does dependency management work?

Dependencies are automatically detected from import/require statements and installed via pip, npm, or go get. For projects, files like requirements.txt, go.mod, or package.json are used.

What are the prerequisites for using Code Sandbox MCP?

Docker must be installed and running on the host system. The installer verifies Docker availability.

How do I configure Code Sandbox MCP for Claude Desktop?

The automated installer adds the configuration to Claude’s config file. Manual configuration paths are provided for Linux (~/.config/Claude/), macOS (~/Library/Application Support/Claude/), and Windows (%APPDATA%\Claude\claude_desktop_config.json).

What security measures are in place?

Code runs in isolated Docker containers with resource limits, separate stdout/stderr streams, read-only project file mounts, and automatic container cleanup after execution.
