Get comprehensive financial statements including balance sheet, income statement, and cash flow data
AI agents call get_financial_data to retrieve information from Vnstock MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and retrieves financial statement data from the Vietnamese stock market database. It has no side effects, does not execute code, does not modify data, and does not trigger transactions. The comprehensive nature of the data returned does not change its fundamental classification as a read operation. Blast radius is minimal—misuse would only expose financial data, not cause any market operations.
