# Sentinel gRPC Adapter Sentinel gRPC Adapter provides client and server interceptor for gRPC services. > Note that currently the interceptor only supports unary methods in gRPC. ## Client Interceptor Example: ```java public class ServiceClient { private final ManagedChannel channel; ServiceClient(String host, int port) { this.channel = ManagedChannelBuilder.forAddress(host, port) .intercept(new SentinelGrpcClientInterceptor()) // Add the client interceptor. .build(); // Init your stub here. } } ``` ## Server Interceptor Example: ```java import io.grpc.Server; Server server = ServerBuilder.forPort(port) .addService(new MyServiceImpl()) // Add your service. .intercept(new SentinelGrpcServerInterceptor()) // Add the server interceptor. .build(); ```
