List company-internal applications shared within your organization.
AI agents call list_company_apps to retrieve information from Now Sdk Ext without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation ('list') on applications, which is a Read category action. The blast radius is low because listing applications does not modify, execute operations, or cause destructive effects. It simply enumerates existing data that would typically be available to authenticated users in the organization.
From the tool's definition Tool name 'list_company_apps' and description 'List company-internal applications shared within your organization' indicate a read-only query operation that retrieves and displays information without modifying any data.

PolicyLayer is an MCP gateway — it sits between your AI agents and Now Sdk Ext, and nothing reaches the server without passing your rules. This is the rule we recommend for list_company_apps:
{
"version": "1",
"default": "deny",
"tools": {
"list_company_apps": {}
}
}list_company_apps is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
