GRPC Server & API

GRPC Service Interface

Flowkit exposes a GRPC service with three core methods:

• ListFunctions — Returns metadata about all registered functions

• RunFunction — Executes a standard function and returns the result

• StreamFunction — Executes a stream-capable function and returns a streaming response

These methods are used internally by the Agent, but can also be accessed by other tools.

Proto Contract

The GRPC service is defined in shared .proto files in the aali-sharedtypes repo.

Example:

service Flowkit {
  rpc RunFunction(FunctionRequest) returns (FunctionResponse);
  rpc StreamFunction(FunctionRequest) returns (stream FunctionResponse);
  rpc ListFunctions(Empty) returns (FunctionList);
}

These proto definitions are shared across Flowkit and Agent.
