Azure DevOps MCP Server with PAT Authentication

A Model Context Protocol (MCP) server for Azure DevOps that uses Personal Access Token (PAT) authentication instead of Azure CLI. This server provides both CLI and HTTP API interfaces for interacting with Azure DevOps services.

✨ Features

• 🔑 PAT Authentication: Uses Personal Access Tokens instead of Azure CLI
• 🌐 HTTP API: REST API endpoints for web applications
• 📡 MCP Protocol: Full Model Context Protocol support
• 🚀 Deploy Ready: Configured for Render.com deployment
• 🛠️ 75 Tools: Comprehensive Azure DevOps functionality

🏗️ Architecture

This server provides two interfaces:

1. CLI Interface (src/index.ts) - Traditional MCP server via stdin/stdout
2. Web Interface (src/server-web.ts) - HTTP REST API for web deployment
