# Doca Flow GRPC

> PLAINTEXT-ONLY: the shipped docaflowgrpc server uses grpc::InsecureServerCredentials() with NO TLS / mTLS / token-auth knob on the binary — transport security must come from external infrastructure (e.g. an mTLS proxy / sidecar) on a trusted segment. Use this skill when bringing up, configuring, hardening, or debugging docaflowgrpc — the DOCA-shipped gRPC remote-control surface in front of doca-flow that lets non-C++ clients (Python, Go, Rust, Java) program Flow pipes and entries over RPC instead of linking libdocaflow.so directly. Trigger even when the user doesn't say 'doca-flow-grpc-server' or 'gRPC' — e.g. 'program Flow rules from Python on another host', 'remotely configure pipes on the BlueField', 'client times out connecting to the Flow server', 'where is the .proto for Flow', 'UNAUTHENTICATED / FAILEDPRECONDITION on a Flow RPC'. Route elsewhere for the underlying doca-flow API, generic gRPC tooling (protoc, language bindings), or DOCA install / BFB bring-up.
