SERVICE ACCOUNT
ANALYTICS
Connect to Google BigQuery using a GCP service account for server-to-server authentication without user login.

audit → user_abc ✓Does the agent access BigQuery (Service Account) as the user or as a shared key?
As the user. Each workspace member authorizes once and Scalekit resolves their credential at request time. Audit logs attribute every action to that user, not a shared service account.
Where is the BigQuery (Service Account) service account key stored?
In Scalekit's managed AES-256 token vault, namespaced per tenant. Refresh is automatic. Revocation is a single dashboard action. Tokens never appear in prompts, logs, or LLM context.
Can I limit what the agent is allowed to do in BigQuery (Service Account)?
Yes. Pass a tool name filter to listScopedTools so the analytics agent only sees the subset you authorize. Pre-API-call scope checks block out-of-policy actions before the request reaches BigQuery (Service Account).
What happens when a user revokes BigQuery (Service Account) access?
The connection is invalidated on the next tool call. Subsequent requests for that user fail closed with a clear error. Other users in the tenant remain unaffected. The event is logged for audit.
Does the service account respect BigQuery IAM?
Yes. Queries run under the connected service account's IAM roles, with dataset ACLs, row-level security, and masking intact. Scalekit vaults the key and adds per-call scope checks plus audit.
