logging.getLogger("google_adk.google.adk.tools.base_authenticated_tool").setLevel(logging.ERROR)

Looking at the adk guide they show how to setup authentication for google calendar.
In my case right now I am using Zapier MCP and (in this case with google sheets) and i keep getting lots of these warnings.
I have authenticated already on the zapier site when first creating the MCP toolsets.
Here is the MCP configuration in for my Agent:
zapier_gSheets = MCPToolset(
connection_params=StreamableHTTPConnectionParams(
url=os.environ["zapier_gSheets"],
),
)
Full warning message:
2025-07-27 18:35:46,940 - WARNING - base_authenticated_tool.py:72 - auth_config or auth_config.auth_scheme is missing. Will skip authentication.Using FunctionTool instead if authentication is not required.
Is this warning just something i should ignore? If so , can I silence it?
