Get current AUM and flows for a specific region.
AI agents call get_aum_snapshot to retrieve information from Northern Trust MCP Layer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial metrics (AUM and flows) for reporting/analysis purposes. It has no side effects, does not execute operations, does not modify data, and does not move money. It is purely informational. While the Northern Trust context is financial, this specific tool merely queries and returns data—a Read operation with low severity even if misused, as it cannot cause financial harm or data loss.
From the tool's definition Tool name 'get_aum_snapshot' and description 'Get current AUM and flows for a specific region' indicate data retrieval only.
