Exercise care in who is allowed to use this toolkit. If exposing to end users, consider that users will be able to make arbitrary requests on behalf of the server hosting the code. For example, users could ask the server to make a request to a private API that is only accessible from the server. Control access to who can submit issue requests using this toolkit and what network access it has. See https://python.langchain.com/docs/security for more information.
