Proxies to a gRPC backend using a descriptors file or server reflection.
Grpc serves as a Management Configuration Protocol (MCP) server, designed to proxy requests to a gRPC backend. It supports configuration either through protobuf descriptor files or by leveraging gRPC server reflection, providing flexibility in how gRPC endpoints are discovered and managed. It supports both Server-Sent Events (SSE) and standard input (STDIN) transports.
