DevJoy.Mcp

A C# .NET library that MCP servers import to gain configuration management capabilities. When integrated into an MCP server, it provides secure, automated configuration management with intelligent handling of sensitive data and seamless distribution across multiple MCP client applications.

Features

• Automatic Sensitive Data Detection: Automatically identifies and securely stores sensitive configuration values
• Multi-Client Distribution: Distributes configurations to VS Code, Claude Desktop, Cursor, and other AI tools
• Client-Specific Distribution: Target specific clients instead of distributing to all
• Dual Storage System: Non-sensitive data in JSON, sensitive data in .env files
• Configuration Hierarchy: Environment variables → Local config → Global config precedence
• Cross-Platform: Works on Windows, macOS, and Linux
• Secure Secret Input: Capture passwords and API keys directly from console, bypassing LLM interfaces entirely

Prerequisites

• .NET 9 SDK

Integration

To integrate this library into your MCP server:

1. Add the NuGet package reference:

   <PackageReference Include="DevJoy.Mcp" Version="1.0.0" />

2. Use the configuration manager in your MCP server:

   using DevJoy.Mcp; using DevJoy.Mcp.Security; var configManager = McpConfig.CreateManager(); // Register your MCP server await configManager.RegisterServerAsync(serverConfig); // Set non-sensitive configuration await configManager.SetServerPropertyAsync("my-server", "host", "localhost"); // Securely capture passwords without LLM exposure await configManager.SetServerPropertySecurelyAsync( "my-server", "password", "Enter password (hidden):" );
