## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why getDEMA is rated Low

getDEMA retrieves and processes historical stock price data to compute a technical analysis indicator (DEMA). This is a pure calculation/retrieval operation with no side effects, no data modification, no execution of external commands, and no financial transactions. It falls squarely under Read category as it queries existing market data and returns analytical results.

From the tool's own definition: "Tool calculates and returns DEMA (Double Exponential Moving Average) based on historical price data. No modification of data occurs. Description states it 'helps users analyze trends' - a read-only analytical operation."

## Use case

AI agents call getDEMA to retrieve information from Financial Modeling Prep MCP 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)
