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

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

  "params": {
    "name": "aggregate_records",
    "arguments": {}

```

## Why aggregate_records is rated Low

The tool name indicates aggregation functionality, which is a read operation that retrieves and summarizes data without side effects. The lack of description lowers confidence slightly, but ServiceNow aggregation functions are typically read-only query operations. Severity is low as aggregation operations on CMDB/table data have no destructive or systemic impact if misused.

From the tool's own definition: "Tool name 'aggregate_records' suggests data aggregation/summarization operations. No description provided, but 'aggregate' typically implies querying and computing statistics on existing data without modification."

## Use case

AI agents call aggregate_records to retrieve information from ServiceNow 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 ServiceNow MCP Server:

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