WHAT IT DOES

What create_ai_agent does on NowAIKit — ServiceNow AI Toolkit

AI agents use create_ai_agent to create or update resources in NowAIKit — ServiceNow AI Toolkit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NowAIKit — ServiceNow AI Toolkit environment.

RISK

Why create_ai_agent is rated Medium

Creating AI agent definitions is a reversible data modification operation that establishes new autonomous entities with security policies. While not immediately destructive, it could enable subsequent harmful actions if a malicious agent definition is created. This is more severe than a simple Read but less severe than Execute (which triggers external operations) or Destructive (irreversible deletion).

From the tool's definition Tool explicitly creates an AI agent definition. Description states it 'Create[s]' a new entity with 'auto-generated ACLs', which are access control lists—security-sensitive configuration.

RECOMMENDED RULE

The rule that runs create_ai_agent 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 create_ai_agent, this is the rule to start with:

create_ai_agent Rate-limited

create_ai_agent 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.
