## Why getBiggestGainers is rated Low

This tool retrieves and displays publicly available market data about stock price movements. It performs no writes, executions, destructive actions, or financial transactions. The worst-case misuse by an AI agent would be returning misleading analysis based on retrieved data, which is a read-layer concern with minimal blast radius. No irreversible actions or financial commitments are possible.

From the tool's own definition: "Tool name 'getBiggestGainers' and description 'Track the stocks with the largest price increases' and 'Identify the companies' indicate data retrieval only."

## Use case

AI agents call getBiggestGainers to retrieve information from Financial Modeling Prep 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)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Financial Modeling Prep:

```json
{
  "version": "1",
