AI agents call pivot_adjustments_by_fs_group to retrieve information from TreeBeam MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and summarizes adjustment data grouped by financial statement type across periods. The verb 'Returns' and the complete absence of mutation language (no create, update, delete, or execute operations) clearly indicates this is a data retrieval operation.
From the tool's definition Returns data aggregated by financial statement group with 'summed adjustment amounts and distinct adjustment counts' — a read-only query operation that retrieves and analyzes existing adjustments without modifying state.
