## Why list_open_swaps is rated Low

This tool retrieves and displays existing swap offers from a pool or marketplace without creating, modifying, deleting, or executing any transactions. It is purely informational browsing of available data. Although the server handles financial operations (USDC transfers, lending), this specific tool does not move money or commit financial obligations—it only reads available swap opportunities.

From the tool's own definition: "Tool name 'list_open_swaps' and description 'Browse available P2P token swap offers' indicate a retrieval/query operation with no side effects. The description explicitly states 'No api_key required', reinforcing its read-only nature."

## Use case

AI agents call list_open_swaps to retrieve information from Ai Agent Bank 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 Ai Agent Bank:

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