ReflexLibs MCP Server Collection

A collection of Model Context Protocol (MCP) servers built with .NET, designed to integrate seamlessly with Claude Desktop. This collection demonstrates various architectural approaches from simple console applications to rich WPF applications with embedded web UIs.

📁 Directory Structure

This project uses a standardized directory structure across Windows systems for both development and deployment.

ReflexLibs App Data Path

All MCP servers are deployed to:

C:\Users\{username}\AppData\Local\ReflexLibs\

Structure:

C:\Users\{username}\AppData\Local\ReflexLibs\
├── McpServer.DotNet.Demo\
│   ├── McpServer.DotNet.Demo.exe          # Main executable
│   ├── logs\                              # Server logs directory

Claude Desktop Configuration Path

Claude Desktop looks for MCP server configurations at:

C:\Users\{username}\AppData\Roaming\Claude\claude_desktop_config.json

Example Configuration:

{
  "mcpServers": {
    "dotnet-demo": {
      "command": "C:\\Users\\{username}\\AppData\\Local\\ReflexLibs\\McpServer.DotNet.Demo\\McpServer.DotNet.Demo.exe",
      "args": ["--verbose"]
    },
    "task-manager": {
      "command": "C:\\Users\\{username}\\AppData\\Local\\ReflexLibs\\McpServer.TaskManager\\McpServer.TaskManager.exe",
      "args": ["--verbose"]
    }
  }
}

🚀 Quick Start

1. Build and Deploy

# Navigate to your MCP server project
cd McpServer.DotNet.Demo

# Build and deploy to standardized location
dotnet publish -c Release -r win-x64 --self-contained -p:PublishSingleFile=true -o "%LOCALAPPDATA%\ReflexLibs\McpServer.DotNet.Demo"

2. Configure Claude Desktop

Create or edit: C:\Users\{username}\AppData\Roaming\Claude\claude_desktop_config.json

Add your server configuration using the absolute path to the deployed executable.

3. Restart Claude Desktop

• Close Claude Desktop completely (from system tray)
• Relaunch Claude Desktop
• Test your MCP server tools
