Get completions usage data for the organization, broken down by time buckets and optional grouping dimensions
AI agents call codex_get_completions_usage to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves usage metrics/analytics data for an organization. The verb 'get' combined with 'usage data' and the lack of any mutative or destructive language indicates a read-only data retrieval operation. There are no side effects, no code execution, no deletions, and no financial transactions involved. The low severity reflects that exposing usage statistics poses minimal risk of direct harm.
From the tool's definition Tool name contains 'get_' and description states it retrieves ('Get completions usage data') without modification or side effects. Action is 'broken down by time buckets and optional grouping dimensions' indicating data querying/reporting only.
