from .prompt import agent_instruction

URL = "https://**************.run.app"

auth_token_provider = auth_methods.get_google_id_token(URL)

toolbox = ToolboxSyncClient(
    URL,
    client_headers={"Authorization": auth_token_provider},

Hi @jeff-got

This seems to be a commonly occuring issue. I have created a PR for the fix: #333

It might take some time to review, merge and release. Meanwhile, do you find recompiling using the new code and seeing if it works for you?

You can use this command to recompile the library using the code present in the PR:

pip install git+https://github.com/googleapis/mcp-toolbox-sdk-python.git@fix-auth

Hi @twishabansal,

Great thank you.

When I try an run that command I get the following error

Apologies for the oversight here. You need to install using this command instead:

pip install git+https://github.com/googleapis/mcp-toolbox-sdk-python.git@fix-auth#subdirectory=packages/toolbox-core
