Ubuntu System Control

A security-hardened MCP server for Ubuntu system control that provides safe file operations, command execution, and system information gathering through multiple layers of protection including path traversal prevention, command injection blocking, resource limits, and comprehensive audit logging. The implementation features configurable security policies (secure vs development modes), symlink resolution, whitelist/blacklist command filtering, and atomic file operations with automatic backups, making it suitable for AI assistants that need controlled access to Ubuntu systems without compromising security. Built with defense-in-depth architecture, it prevents common attack vectors like directory traversal, command injection, and resource exhaustion while maintaining full audit trails for compliance and monitoring.
