# C# MCP Server Creation Create Model Context Protocol servers using the official C# SDK (`ModelContextProtocol` NuGet package) and the `dotnet new mcpserver` project template. Servers expose tools, prompts, and resources that LLMs can discover and invoke via the MCP protocol. ## When to Use - Starting a new MCP server project from scratch - Adding tools, prompts, or resources to an existing MCP server - Choosing between stdio (`--transport local`) and HTTP (`--transport remote`) transport - Setting up ASP.NET Core hosting for an HTTP MCP server - Wrapping an external API or service as MCP tools ## Stop Signals - **Server already exists and needs debugging?** → Use `mcp-csharp-debug` - **Need tests or evaluations?** → Use `mcp-csharp-test` - **Ready to publish?** → Use `mcp-csharp-publish` - **Building an MCP client, not a server** → This skill is server-side only ## Inputs | Input | Required | Description | |-------|----------|-------------| | Transport type | Yes | `stdio` (local/CLI) or `http` (remote/web). Ask user if not specified — default to stdio | | Project name | Yes | PascalCase name for the project (e.g., `WeatherMcpServer`) | | .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 | ## Workflow > **Commit strategy:** Commit after completing each step so scaffolding and implementation are separately reviewable. ### Step 1: Verify pre...
