Returns historical split events.
AI agents call get_splits to retrieve information from AlphaVantage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical stock split data from the AlphaVantage API—a pure read operation with no side effects. It does not modify data, execute trades, move money, or trigger external operations. The low severity reflects that accessing public historical financial data poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'get_splits' and description 'Returns historical split events' indicate a retrieval operation that queries financial data without modification or execution of trades.
