- IChatClient Integration: Leverage AI capabilities for text processing
- Dependency Injection: Utilize .NET DI container for service management
- Configuration System: Support multiple configuration sources
🧪 Development
Adding New Tools
- Create a new static method in the appropriate tool class
- Add the
[McpServerTool]attribute with name and description - Include parameter descriptions using
[Description]attributes - Implement the tool logic using IChatClient when appropriate
Example:
[McpServerTool(Name = "MyNewTool"), Description("Description of what the tool does")]
public static async Task<string> MyNewTool(
IMcpServer thisServer,
[Description("Input parameter description")] string input,
CancellationToken cancellationToken = default)
{
// Tool implementation
ChatMessage[] messages = [
new(ChatRole.System, "System prompt for the AI"),
new(ChatRole.User, $"User prompt with {input}")
];
ChatOptions options = new()
{
MaxOutputTokens = 200,
Temperature = 0.5f,
};
var response = await thisServer.AsSamplingChatClient().GetResponseAsync(messages, options, cancellationToken);
return $"Result: {response}";
}

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
