DevOps Enhanced MCP

# DEVOPS-MCP PROJECT - ACHIEVEMENT ARCHIVE **Project Status**: ✅ **COMPLETED & ARCHIVED (2025-07-22)** **GitHub Repository**: <https://github.com/wangkanai/devops-mcp> **Achievement Level**: 🏆 **PRODUCTION SUCCESS** - All objectives exceeded --- ## 🎯 PROJECT OVERVIEW ### Mission Statement Develop a custom MCP (Model Context Protocol) server enabling Claude Code to dynamically switch Azure DevOps authentication contexts based on directory location, providing seamless multi-project workflow integration. ### Core Problem Solved **Challenge**: Claude Code MCP servers inherit static environment variables at startup, preventing dynamic project-specific Azure DevOps authentication when switching between RiverSync and Mula project directories. **Solution**: Custom dynamic MCP server with intelligent directory detection and local configuration file management, providing transparent Azure DevOps context switching without Claude Code restarts. --- ## ✅ IMPLEMENTATION ACHIEVEMENTS ### **🚀 Core Functionality -
