WHAT IT DOES

What snow_list_applications does on Serac

AI agents call snow_list_applications to retrieve information from Serac without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why snow_list_applications is rated Low

This is a read-only query tool that retrieves metadata about ServiceNow applications without any side effects. It allows filtering and listing existing data but cannot create, modify, delete, or execute operations. The blast radius of misuse is minimal—an attacker could enumerate the ServiceNow instance's application landscape but cannot act upon it without other tools.

From the tool's definition Tool name and description explicitly describe listing/querying: 'List all scoped applications' and 'Use to find available scopes' and 'see which applications are active/inactive'.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs snow_list_applications safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Serac, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For snow_list_applications, this is the rule to start with:

snow_list_applications Allowed

snow_list_applications is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "snow_list_applications": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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

Can I rate-limit snow_list_applications? +

Yes. Add a rate_limit block to the snow_list_applications rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block snow_list_applications completely? +

Set action: deny in the PolicyLayer policy for snow_list_applications. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
