  final serverResult = McpServer.create((name: 'my-server', version: '1.0.0'));

  final server = switch (serverResult) {
    Success(:final value) => value,
    Error(:final error) => throw Exception(error),
  };

  server.registerTool(
    'echo',
    (description: 'Echo input back', inputSchema: null),
    (args, meta) async => (
      content: [(type: 'text', text: args['message'] as String)],
      isError: false,
    ),
  );

  final transport = switch (createStdioServerTransport()) {
    Success(:final value) => value,
    Error(:final error) => throw Exception(error),
  };

  await server.connect(transport);
}
