## Description

The pkgx-mcp server provides Claude with secure access to thousands of open-source command-line tools through pkgx, a package manager that requires no installation. It implements two primary tools for running commands - one accepting command lines and another taking structured arguments - both executing in a sandboxed environment that prevents filesystem writes outside designated areas. The server includes safety features like root user prevention and sandbox profiles on macOS, while also providing resource endpoints to list available programs and mash scripts. This implementation is particularly useful for scenarios requiring access to development tools, data processing utilities, or any CLI program without compromising system security.
