Google BigQuery remote MCP conventions (preview) — GCP Workload Identity Federation auth never a static service-account key, a read-only bigquery.jobUser + dataViewer role, mandatory partition pruning, and in-place query streaming. Use when querying BigQuery, wiring the BigQuery MCP, or setting up read-only warehouse access on GCP.

- **Preview status (Jan 2026)** — re-verify GA status each quarter.
BIGQUERY_SERVICE_ACCOUNT_KEY_JSON is refused by the
block-static-warehouse-creds.sh shared hook.bigquery.jobUser + bigquery.dataViewer. No bigquery.dataEditor.block-unbounded-sql.sh
(no WHERE) and also waste cost; review every plan.This addon's BigQuery MCP carries a secret OAuth token, so it is not
auto-started by the plugin. Add it to your project's .mcp.json only when
you want governed BigQuery access, then set BIGQUERY_OAUTH_TOKEN in your
environment (mint it via Workload Identity Federation — never a static
service-account key):
