## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why list_queues is rated Low

This tool performs data retrieval only—it queries and returns information about queues in a Redis connection. There are no side effects, no data modification, and no external operations triggered. It is purely observational and falls squarely into the Read category with low severity.

From the tool's own definition: "Tool name 'list_queues' and description 'List all queues in the current connection' indicate a query operation that retrieves queue metadata without modifying any state. The verb 'list' is a classic Read operation."

## Use case

AI agents call list_queues to retrieve information from BullMQ MCP Server 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 BullMQ MCP Server:

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