List scoped applications (custom apps) installed in the instance
AI agents call list_scoped_apps to retrieve information from ServiceNow-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates installed custom applications in a ServiceNow instance. It performs a read-only query with no side effects, no data modification, no code execution, and no destructive capability. The blast radius of misuse is minimal—an agent could discover what apps are installed, but cannot alter configuration, execute code, or compromise systems through listing alone.
From the tool's definition Tool name 'list_scoped_apps' and description 'List scoped applications (custom apps) installed in the instance' indicate a retrieval/query operation with no modification or execution of code.
Attacks that exploit this kind of access
List scoped applications (custom apps) installed in the instance. It is categorised as a Read tool in the ServiceNow-MCP MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow- MCP server in PolicyLayer and add a rule for list_scoped_apps: 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 ServiceNow-MCP. Nothing to install.
list_scoped_apps 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 list_scoped_apps 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 list_scoped_apps. 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.
list_scoped_apps is provided by the ServiceNow- MCP server (tedorigawa001/servicenow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
