Create MCP servers using the C# SDK and .NET project templates. Covers scaffolding, tool/prompt/resource implementation, and transport configuration for stdio and HTTP. USE FOR: creating new MCP server projects, scaffolding with dotnet new mcpserver, adding MCP tools/prompts/resources, choosing stdio vs HTTP transport, configuring MCP hosting in Program.cs, setting up ASP.NET Core MCP endpoints with MapMcp. DO NOT USE FOR: debugging or running existing servers (use mcp-csharp-debug), writing tes

| .NET SDK version | Recommended | .NET 10.0+ required. Check with dotnet --version |
| Service/API to wrap | Recommended | External API or service the tools will interact with |
Commit strategy: Commit after completing each step so scaffolding and implementation are separately reviewable.
Confirm .NET 10+ SDK: dotnet --version (install from https://dotnet.microsoft.com if < 10.0)
Check if the MCP server template is already installed:
dotnet new list mcpserver
