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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_update_set",
    "arguments": {}

## Why get_update_set is rated Low

This tool retrieves metadata about an update set (a ServiceNow configuration container) by its system ID. It performs a read-only query with no side effects, ability to modify data, or destructive capability. The blast radius of misuse is minimal—an attacker could enumerate update sets but cannot alter configurations, delete data, or trigger financial transactions.

From the tool's own definition: "Tool name is 'get_update_set' and description states 'Get details of a specific update set by sys_id' — retrieval only, no modification or deletion."

## Use case

AI agents call get_update_set 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": {
    "get_update_set": {}
  }
}
```
