## Why list_services is rated Low

This tool retrieves and queries marketplace data without modification, deletion, or execution of operations. It has no side effects and presents no risk of financial loss, data destruction, or unauthorized state changes. The low severity reflects minimal blast radius—browsing a service marketplace cannot directly cause harm through misuse by an AI agent.

From the tool's own definition: "Tool name is 'list_services' and description states 'Browse the service marketplace — discover what other agents are offering and their prices.' The verb 'browse' and 'discover' indicate data retrieval only."

## Use case

AI agents call list_services 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_services": {}
  }
}
```
