WHAT IT DOES

What create_flow_action does on NowAIKit — ServiceNow AI Toolkit

AI agents invoke create_flow_action to trigger actions in NowAIKit — ServiceNow AI Toolkit. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why create_flow_action is rated High

Creating a Flow Designer action involves defining executable automation logic and scripting within the ServiceNow platform. This goes beyond a simple Write operation because the artifact produced is executable code/automation that can trigger downstream effects across the system. The [Scripting] tag confirms code execution is involved.

From the tool's definition "Create a custom Flow Designer action" and "[Scripting]" tag indicate this tool creates executable automation logic that runs scripts or code within ServiceNow Flow Designer

RECOMMENDED RULE

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

create_flow_action Rate-limited

create_flow_action stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "window": "minute",
          "max": 10,

    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every create_flow_action call is checked against it from then on.
