Credentials it needs

BQ_MCP_ENVIRONMENTSJSON map of environment name to BigQuery settings (project, location, impersonate, dataset_allowlist, byte caps). Omit when using a config file at ~/.config/data-platform-mcp/config.toml.
BQ_MCP_DEFAULT_ENVIRONMENTEnvironment used when a tool call omits the environment argument.
BQ_MCP_CONFIGPath to a TOML config file, overriding ~/.config/data-platform-mcp/config.toml.
BQ_IMPERSONATE_SERVICE_ACCOUNTRead-only service account to impersonate, making read-only a property of the identity rather than of this code. Create it with `data-platform-mcp setup`.
BQ_PROJECTGCP project whose BigQuery datasets are queried. Falls back to the project associated with Application Default Credentials.
BQ_LOCATIONBigQuery location for jobs and datasets. Defaults to US.
BQ_CODE_ASSET_LOCATIONRegion holding BigQuery Studio notebooks and saved queries. Separate from BQ_LOCATION and usually different: code assets are regional and Dataform rejects multi-regions, so datasets in US typically pair with code assets in a region like us-central1. A wrong region returns an empty list rather than an error. Defaults to BQ_LOCATION.
BQ_DATASET_ALLOWLISTComma-separated dataset IDs the server may read. Empty means all datasets.
BQ_WARN_BYTESScan size above which a query is returned for user confirmation instead of run. Defaults to 1 GiB.
BQ_MAX_BYTES_BILLEDHard per-query scan cap; a query estimated above this never runs. Defaults to 5 GiB.
BQ_MCP_AUDIT_LOGPath for the JSONL tool-call audit log, or 'off' to disable it. SQL text is never recorded, only a hash and a length.
