What list_deployment_history does on NowAIKit — ServiceNow AI Toolkit
AI agents call list_deployment_history to retrieve information from NowAIKit — ServiceNow AI Toolkit without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_deployment_history is rated Low
This tool retrieves historical records of deployments and installations. It performs a read-only query against deployment logs and does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—an attacker could enumerate deployment history to understand the system's change timeline, but cannot cause data loss, execute code, or affect system operations.
From the tool's definition Tool name 'list_deployment_history' and description 'List deployment history — committed update sets and app installs over time' indicate a query/retrieval operation with no modification or destructive capability.
Attacks that exploit this kind of access
The rule that runs list_deployment_history safely
PolicyLayer is an MCP gateway: it sits between your AI agents and NowAIKit — ServiceNow AI Toolkit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_deployment_history, this is the rule to start with:
list_deployment_history is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every list_deployment_history call is checked against it from then on.
