Overview

C# MCP Server Generator is a skill that creates a complete Model Context Protocol (MCP) server project in C# using .NET 8.0+. It generates a properly structured console application with the ModelContextProtocol NuGet package, Host builder pattern with dependency injection, stdio transport, automatic tool discovery, and proper logging configuration that avoids interfering with the MCP communication channel.

Key Features

• Production-Ready Project Setup - Creates a .NET 8.0+ console application with ModelContextProtocol (prerelease) and Microsoft.Extensions.Hosting NuGet packages properly configured
• Host Builder Pattern - Uses Host.CreateApplicationBuilder for dependency injection and lifecycle management with AddMcpServer() and stdio transport
• Automatic Tool Discovery - Implements WithToolsFromAssembly() for automatic MCP tool registration using [McpServerToolType] and [McpServerTool] attributes
• Proper Logging - Configures all logs to stderr to avoid interfering with the stdio transport communication channel
• Rich Tool Templates - Provides patterns for file operations, data processing, external API integrations, system operations, and database queries with proper validation and error handling

Who is this for?

This skill is for C# developers who want to build MCP servers to expose custom tools and capabilities to AI assistants like Claude or GitHub Copilot. It is particularly useful for .NET developers who want to leverage the Host builder pattern and dependency injection while following Microsoft's conventions for building MCP-compatible services.
