Secure code execution sandbox for Claude — run Python, JavaScript, and shell commands
Secure code execution sandbox for Claude — run Python, JavaScript, and shell commands
This MCP server implements arbitrary Python code execution without any authentication, authorization, or sandboxing mechanisms. The code directly executes user-supplied Python in a persistent global namespace with full access to the Python standard library, filesystem, network, and system commands. Combined with the `repl_install` tool that runs `pip install` without restrictions, this creates a critical remote code execution vulnerability. The server is inherently unsafe for multi-user or untrusted environments. Package verification found 1 issue.
