Retrieve an asset allocation summary for a specific account.
AI agents call get_position_summary 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 and queries existing financial data (asset allocation) for display purposes. There is no modification, deletion, execution of code, or financial transaction occurring. While it accesses sensitive financial information (account positions), the read-only nature and lack of side effects place it in the Read category.
From the tool's definition Tool name 'get_position_summary' and description 'Retrieve an asset allocation summary for a specific account' indicate data retrieval with no modification.
