Quality MCP Server 🏍️

An MCP server that analyzes to your codebase, with plugin support for DCD and Simian. 🏍️ "The only Zen you find on the tops of mountains is the Zen you bring up there."

📚 Recommended Reading: Zen and the Art of Motorcycle Maintenance by Robert M. Pirsig - This project embodies the philosophy of quality as a way of being, not just a technical achievement. The book's exploration of "Quality" as an undefinable but recognizable concept aligns perfectly with our approach to code analysis and improvement.
