Suggestion
I assume the mcp-gateway project was updated such that the following the exact directions of the linked URL does not work out of the box.
I recommend adding either a new step between step 1 and 2, or adding to step 1 details for either disabling the bearer token requirement by adding
- --allow-unauthenticated
to the compose.yaml file, or getting that bearer token generated by the mcp-gateway container into the adk container
