grpcurl is a tool for communicating with gRPC servers from the command line, the gRPC counterpart of curl, which sends requests to HTTP servers. If the server supports reflection or you specify .proto files, it can list services and methods; when you write a request message as JSON and send it, it encodes it as binary protobuf, makes the call, and prints the response as JSON. It is used to debug gRPC APIs or call them from scripts without writing dedicated client code.
