## Why evaluate_strategy is rated Low

This tool performs strategy backtesting/evaluation logic to inform decision-making. It reads market data and strategy parameters to produce analytical output. While it supports both built-in and custom strategies, 'evaluate' means assessment only, not execution of trades or financial transactions.

From the tool's own definition: "Tool evaluates trading strategies against current market conditions and returns analysis. No keywords indicating execution (execute, run, trigger), modification (create, update, set), deletion, or financial transaction."

## Use case

AI agents call evaluate_strategy to retrieve information from Fathom Fyi 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 Fathom Fyi:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "evaluate_strategy": {}
  }
}
```
