# GRPC server
## Integrating GRPC services
### Install Evans
```shell
brew install evans
```
Start your bbgo with gRPC server option:
```shell
go run ./cmd/bbgo run --config grid_kucoin.yaml --debug --enable-grpc
```
The gRPC server port is located at 6688, you can use evans to connect to the gRPC server:
```shell
evans --host localhost --port 6688 -r repl
```
```shell
bbgo@localhost:6688> package bbgo
bbgo@localhost:6688> show service
bbgo@localhost:6688> show message
```
You can use evans to get the description of a message:
```shell
bbgo@localhost:6688> desc QueryKLinesRequest
