WHAT IT DOES

What create_flow_action does on ServiceNow-MCP

AI agents invoke create_flow_action to trigger actions in ServiceNow-MCP. 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 logic/scripts that will run as part of automated workflows in ServiceNow. The [Scripting] tag confirms code execution capability is involved. While it is technically a 'create' (Write) operation, the artifact produced is executable workflow automation code, making Execute the most appropriate and severe category.

From the tool's definition 'Create a custom Flow Designer action' and '[Scripting]' tag indicate this tool creates executable workflow automation logic involving scripting

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_flow_action safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ServiceNow-MCP, 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_flow_action": {
      "limits": [
        {
          "counter": "create_flow_action_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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