AI agents call bigquery_auth_status to retrieve information from Mimi Seed without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only information retrieval operation. It checks the authentication configuration state without making any changes to data, executing commands, or triggering external operations. The severity is low because exposing authentication status alone does not create immediate operational risk, though the information could inform further attacks.
From the tool's definition The tool name 'bigquery_auth_status' and description indicate it 'queries/checks the current BigQuery authentication status' (조회 — 확인 means 'query/check').
