⚙️ Usage

Use an extension method to register a specific MCP function/tool

Register single function or tool

// 💡Stdio
await kernel.Plugins.AddMcpFunctionsFromStdioServerAsync("GitHub", "npx", ["-y", "@modelcontextprotocol/server-github"]);

// 💡SSE
await kernel.Plugins.AddMcpFunctionsFromSseServerAsync("GitHub", new Uri("http://localhost:12345"));

Register MCP Server(s) from Claude Desktop configuration

It’s also possible to register all Stdio MCP Servers which are registered in Claude Desktop:

// 💡Stdio MCP Tools defined in claude_desktop_config.json
await kernel.Plugins.AddToolsFromClaudeDesktopConfigAsync(cancellationToken: cts.Token);

💻 Full Stdio Example

Code

var builder = Kernel.CreateBuilder();
builder.Services.AddLogging(c => c.AddDebug().SetMinimumLevel(LogLevel.Trace));

builder.Services.AddOpenAIChatCompletion(
    serviceId: "openai",
    modelId: "gpt-4o-mini",
    apiKey: Environment.GetEnvironmentVariable("OPENAI_API_KEY")!);

var kernel = builder.Build();

// 💡 Add this line to enable MCP functions from a Stdio server named "Everything"
await kernel.Plugins.AddMcpFunctionsFromStdioServerAsync("Everything", "npx", ["-y", "@modelcontextprotocol/server-github"]);

var executionSettings = new OpenAIPromptExecutionSettings
{
    Temperature = 0,
    FunctionChoiceBehavior = FunctionChoiceBehavior.Auto()
};

var prompt = "Please call the echo tool with the string 'Hello Stef!' and give me the response as-is.";
var result = await kernel.InvokePromptAsync(prompt, new(executionSettings)).ConfigureAwait(false);
Console.WriteLine($"\n\n{prompt}\n{result}");
