I've tried chat, email, and here and inevitably I stop getting replies--Im just trying to figure out this Big Query connection and everyime I ask for support I stop getting replies.

Hey, sorry about that. If I understand correctly you've connected to Big Query in the developer platform (service acc) and trying to use it in Composio MCP in claude?

Yes, and you mentioned that I should click the link Claude sends that expires to connect my composio account to Claude. Except this link just asks me to log into the Google account, only to say the app has been blocked by Google

@sabraham Sorry - my bad here. The Composio MCP connect auth flow looks very similar across BigQuery auth modes, so I initially assumed this was the other path. In Composio For You, when a toolkit supports multiple auth schemes, we currently route through the Composio-managed OAuth flow where it’s available. For BigQuery, that means the Claude connect link is going through the managed auth path, and we don’t yet support switching the auth scheme from Composio For You. I’ve escalated this internally and are looking into it on priority. I’ve also shared this feedback with our product team, and I’ll follow up here as soon as we have the confirmed next step.

@Abhishek thank you for looking into it. any word on next steps?

@sabraham We're still working on solving the 'App blocked' issue, but service account support is not currently available in Composio for You. Would it unblock you if you use the OAuth2 method, or do you only want to use the service account one?
