## Why getRSI is rated Low

RSI is a read-only technical indicator calculation that queries and analyzes existing market data without creating, modifying, deleting, or executing any irreversible actions. The tool generates insights from historical data but does not alter state, execute commands, or involve financial transactions. This is purely a data retrieval and analytical operation.

From the tool's own definition: "Tool name 'getRSI' and description 'Calculate the Relative Strength Index (RSI) for a stock' indicates retrieval and calculation of a technical analysis metric from historical price data. No modification, deletion, or financial transaction occurs."

## Use case

AI agents call getRSI 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.

## Recommended policy (PolicyLayer)
