HelloMCP: Production-Ready Model Context Protocol Servers

Comprehensive MCP implementations in .NET, Docker, and Azure Functions

References:

• Model Context Protocol Specification
• How to MCP: Complete Guide
• GitHub Copilot Coding Agent Environment Setup

This project demonstrates multiple production-ready approaches to creating Model Context Protocol (MCP) servers, from learning implementations to enterprise-grade solutions:

🚀 Featured: Official .NET MCP SDK Server ⭐

NEW: mcp-sdk-dotnet/ — Production-ready MCP server using Microsoft's official SDK

• ✅ Official Microsoft MCP SDK with full protocol compliance
• ✅ 20+ Advanced Tools across 6 categories (system, web, diagnostics, monitoring)
• ✅ Docker & VS Code Integration ready
• ✅ Attribute-based tool registration with dependency injection
• ✅ Real-time performance monitoring and health checks
• ✅ Comprehensive validation & testing built-in

📁 All Implementations

Implementation	Status	Architecture	Best For
🏆 MCP SDK .NET	✅ Production	Official Microsoft SDK, stdio transport	Enterprise & Production
🐳 Docker MCP	✅ Complete	Containerized REST API	Cloud Deployment
⚡ .NET MCP	✅ Complete	Custom HTTP implementation	Learning & Experimentation
☁️ Azure Functions	🚧 In Progress	Serverless architecture	Serverless & Auto-scaling

🎯 Quick Start

Option 1: Official SDK Server (Recommended)

cd mcp-sdk-dotnet
dotnet run
# Ready for VS Code Insiders integration!

Option 2: Docker Production Deployment

cd docker-mcp
docker-compose up -d
# Accessible at http://localhost:5090

Option 3: Custom .NET Development Server

cd dotnet-mcp/McpServer
dotnet run
# Development server with hot reload

🎨 VS Code Integration

For VS Code Insiders Users:

1. Add to your mcp.json:

{
  "mcpServers": {
    "DotNet MCP SDK": {
      "command": "dotnet",
      "args": ["run", "--project", "path/to/mcp-sdk-dotnet"],
      "env": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

2. Start using tools immediately:

   • Ask Copilot: "Use the GetSystemInfo tool to show my system specs"
   • Ask Copilot: "Use the GetPerformanceMetrics tool to check server health"
   • Ask Copilot: "Use the HealthCheck tool to test https://github.com"

3. Verification script included:

cd mcp-sdk-dotnet
.\verify-mcp-integration.ps1
