Knapcode Samplemcpserver

joelverhagen/knapcode.samplemcpserver

This is a demonstration server built with the C# MCP SDK that exposes two simple tools: generating random numbers and returning random weather conditions. It's designed as a teaching example rather than a production tool, showing C# developers how to package and distribute MCP servers via NuGet. The weather tool accepts configurable choices through environment variables. Reach for this when you're learning the C# MCP SDK implementation patterns or need a minimal working example to fork for your own .NET based server. The source includes complete setup instructions for both local development and NuGet package distribution.

This README was created using the C# MCP server template project. It demonstrates how you can easily create an MCP server using C# and then package it in a NuGet package.

See aka.ms/nuget/mcp/guide for the full guide.

Checklist before publishing to NuGet.org

  • Test the MCP server locally using the steps below.
  • Update the package metadata in the .csproj file, in particular the <PackageId>.
  • Update .mcp/server.json to declare your MCP server's inputs.
  • Pack the project using dotnet pack.
