APIs, databases, file systems, etc.
    Please scope the permissions of each tools to the minimum required for the
    application.
    For example, if an application only needs to read from a database,
    the database tool should not be given write permissions. Moreover
    consider scoping the permissions to only allow accessing specific
    tables and impose user-level quota for limiting resource usage.
    Please read the APIs of the individual tools to determine which configuration
    they support.
    See [Security](https://python.langchain.com/docs/security) for more information.
    Args:
        tool_names: name of tools to load.
        llm: An optional language model, may be needed to initialize certain tools.
        callbacks: Optional callback manager or list of callback handlers.
            If not provided, default global callback manager will be used.
