+# Generate C# MCP Server
+
+Create a complete Model Context Protocol (MCP) server in C# with the following specifications:
+
+## Requirements
+
+1. **Project Structure**: Create a new C# console application with proper directory structure
+2. **NuGet Packages**: Include ModelContextProtocol (prerelease) and Microsoft.Extensions.Hosting
+3. **Logging Configuration**: Configure all logs to stderr to avoid interfering with stdio transport
+4. **Server Setup**: Use the Host builder pattern with proper DI configuration
+5. **Tools**: Create at least one useful tool with proper attributes and descriptions
+6. **Error Handling**: Include proper error handling and validation
+
+## Implementation Details
+
+### Basic Project Setup
+- Use .NET 8.0 or later
+- Create a console application
+- Add necessary NuGet packages with --prerelease flag
+- Configure logging to stderr
+
+### Server Configuration
+- Use `Host.CreateApplicationBuilder` for DI and lifecycle management
+- Configure `AddMcpServer()` with stdio transport
+- Use `WithToolsFromAssembly()` for automatic tool discovery
+- Ensure the server runs with `RunAsync()`
+
+### Tool Implementation
+- Use `[McpServerToolType]` attribute on tool classes
+- Use `[McpServerTool]` attribute on tool methods
+- Add `[Description]` attributes to tools and parameters
+- Support async operations where appropriate
+- Include proper parameter validation
+
+### Code Quality
+- Follow C# naming conventions
+- Include XML documentation comments
+- Use nullable reference types
+- Implement proper error handling with McpProtocolException
+- Use structured logging for debugging
+
+## Example Tool Types to Consider
+- File operations (read, write, search)
+- Data processing (transform, validate, analyze)
+- External API integrations (HTTP requests)
+- System operations (execute commands, check status)
+- Database operations (query, update)
+
+## Testing Guidance
+- Explain how to run the server
+- Provide example commands to test with MCP clients
+- Include troubleshooting tips
+
+Generate a complete, production-ready MCP server with comprehensive documentation and error handling.
