Connect Codex to Google BigQuery and GitLab
What happens next
Set up in minutes
Choose where it runs
On your computer through your own Codex, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Google BigQuery
A preset of real Google BigQuery operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Pick what it can do in GitLab
A preset of real GitLab operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Google BigQuery
One sign-in. The agent acts through your account, scoped to the operations you picked.
Connect GitLab
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your Codex first calls in.
Run this in your terminal
<your-link> is your personal server URL — setup mints it for you.
