List all scoped applications (sys_app) in the ServiceNow instance. Use to find available scopes before switching, see which applications are active/inactive, or decide which scope to use for development. Search options: filter by name (partial match), scope (partial match, e.g.
AI agents call snow_list_applications to retrieve information from Serac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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'.

Register the Serac MCP server in PolicyLayer and add a rule for snow_list_applications: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Serac. Nothing to install.
snow_list_applications is a Read tool with low risk. Read-only tools are generally safe to allow by default.
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.
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.
snow_list_applications is provided by the Serac MCP server (serac-labs/serac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
snow_list_applications is one line of Serac's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
