## Why retrieve_balance is rated Low

This tool queries account balance information without creating, modifying, or deleting data. It has no side effects and does not move money or commit financial obligations. While it accesses financial information (which could inform decisions), the act of retrieval itself poses minimal risk—it is purely observational.

From the tool's own definition: "Tool name 'retrieve_balance' and description 'Retrieve account balance' indicate a read-only query operation that retrieves financial data without modifying it."

## Use case

AI agents call retrieve_balance to retrieve information from Stripe 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 Stripe:

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