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

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

## Why getBiggestLosers is rated Low

getBiggestLosers retrieves and queries market data about stock price performance. There are no side effects: it does not create, modify, delete, or execute anything. The tool simply returns market information, making it a standard Read operation with low risk if misused by an AI agent (worst case: an agent queries losers repeatedly or uses the data in subsequent decisions, neither of which causes harm).

From the tool's own definition: "Tool provides 'Access data on the stocks with the largest price drops' and 'Identify companies' and 'track the stocks' — purely descriptive operations with no modification, deletion, or execution capability."

## Use case

AI agents call getBiggestLosers 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)

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

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