## Why getDEMA is rated Low

This tool performs a technical analysis calculation on historical stock price data. It retrieves and processes data to generate a moving average metric, which is a standard read-only financial analysis operation. No data is modified, created, or deleted; no trades or financial transactions are executed; no external systems are affected. The output is purely informational and advisory.

From the tool's own definition: "Tool 'getDEMA' calculates and returns the Double Exponential Moving Average for historical price data. The description states it 'helps users analyze trends' and 'identify potential buy or sell signals' — these are analytical computations on existing market…"

## Use case

AI agents call getDEMA to retrieve information from Financial Modeling Prep (FMP) Server  without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
