## Why get_all_markets is rated Low

This tool retrieves and queries market data from JustLend DAO without making any changes to state, executing code, or committing financial transactions. It is a pure read operation that gathers informational metrics about lending markets. The minimal blast radius reflects that an AI agent's misuse would only result in reading unnecessary or repetitive data, not harm to assets or systems.

From the tool's own definition: "Tool name 'get_all_markets' and description 'Get overview data for ALL JustLend markets including supply APY, borrow APY, mining rewards APY' indicate a data retrieval operation with no modification or execution capability."

## Use case

AI agents call get_all_markets to retrieve information from Justlend 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 Justlend:

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