WARNING - base_authenticated_tool.py:72 - auth_config or auth_config.auth_scheme is missing.

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?

It's ignorable - MCPTool extends BaseAuthenticatedTool, so there's nothing you can do to get rid of the warning

[jnhyperion]

try this in the beginning of your scripts:

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

you can ignore it and if you don't want to see it add --log_level ERROR to adk web or adk api_server

[surajksharma07]

@Allena101 As dylan-apex noted this warning is expected whenever an auth-based tool like MCPTool runs without an auth_config so it's safe to ignore. If you'd rather not see it jnhyperion's logger tweak or seanzhou1023's --log_level ERROR flag on adk web/api_server will quiet it. Closing this out since it looks addressed, feel free to reopen or comment if you're still running into it.
