## Why list_retainers is rated Low

This tool retrieves and displays information about retainer agreements, usage metrics, and client details. It has no side effects—it only queries and presents data. There is no indication it modifies, creates, deletes, or executes anything. The filtering capability ('Filter by status or client') is a read-only parameter that narrows the query results.

From the tool's own definition: "Tool name is 'list_retainers' and description states 'List active retainer trackers' and 'Shows deliverable/hour usage against limits, billing period, and client details.' This is purely a query/retrieval operation with no modification, deletion, or execution…"

## Use case

AI agents call list_retainers to retrieve information from Businys 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 Businys:

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