Pattern Store MCP 🧩

The Pattern Store MCP (Model Context Protocol) server stores and retrieves code patterns, conventions, and project-specific learnings for the Cracked Jacked Claude framework.

Features

• Pattern Storage: Store code patterns with metadata (category, language, quality score)
• Semantic Search: Search patterns by query, category, language, or quality
• Quality Tracking: Track and update pattern quality scores
• Usage Analytics: Track pattern usage frequency
• Category Management: Organize patterns by categories
