Update an existing incident in ServiceNow by sys_id.
AI agents use update_servicenow_incident to create or update resources in Apple Shortcuts — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Apple Shortcuts environment.
This tool modifies existing data (incident records) in ServiceNow reversibly. It is not destructive (does not delete), not financial, and not arbitrary code execution. The severity is high because unauthorized updates to incident records could impact organizational incident management, affect SLAs, cause incorrect escalations, or disrupt operational workflows.
From the tool's definition Tool name contains 'update' and description states 'Update an existing incident in ServiceNow by sys_id', indicating modification of data in an external system.
Documented attack patterns abuse exactly the kind of access update_servicenow_incident gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apple Shortcuts, and nothing reaches the server without passing your rules. This is the rule we recommend for update_servicenow_incident:
{
"version": "1",
"default": "deny",
"tools": {
"update_servicenow_incident": {
"limits": [
{
"counter": "update_servicenow_incident_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_servicenow_incident stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
