## Description

This MCP server, developed by Wes Higbee, enables AI assistants to interact with macOS system preferences through the 'defaults' command. It provides tools for listing domains, finding settings, reading preference values, and writing new settings. The server implements subprocess calls to execute system commands, offering a straightforward interface for AI systems to query and modify macOS configurations. By connecting AI capabilities with low-level system operations, this implementation empowers AI assistants to perform tasks like customizing user interfaces, adjusting system behaviors, or troubleshooting macOS issues. It is particularly useful for applications requiring automated macOS configuration, user preference management, or any scenario where an AI system needs to interact with and reason about macOS system settings.
