## Description

Shell Command MCP Server provides a secure environment for executing shell commands within a Docker container, offering isolation from the host system. Developed by Nakamura Kazutaka, this TypeScript implementation uses the MCP SDK to expose a single tool that allows running any bash command with configurable working directory, environment variables, and timeout settings. The server runs as a non-root user in the container and includes Kubernetes tools (kubectl, helm, kustomize, k9s), making it particularly useful for DevOps workflows, infrastructure management, and secure command execution in AI-assisted development environments.
