## Why cfpb_complaint_aggregations is rated Low

This tool performs data retrieval and aggregation only. It queries complaint data to generate statistics (counts grouped by facets like product, issue, company, state, etc.) with no capability to modify, delete, or execute operations. The read-only nature and lack of side effects clearly place it in the Read category with low severity, as misuse by an AI agent would only expose or analyze existing public data.

From the tool's own definition: "Tool description states it 'aggregates complaint counts' and is 'useful for ranking companies by complaint volume or finding the most common issue categories.' These are read-only analytics operations that retrieve and summarize existing public complaint data…"

## Use case

AI agents call cfpb_complaint_aggregations to retrieve information from Livedatalink 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 Livedatalink:

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