List Virtual Agent topics available in the instance (latest release: streaming VA API)
AI agents call get_virtual_agent_topics 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 queries and returns a list of Virtual Agent topics from the ServiceNow instance. It performs no creation, modification, deletion, or execution of operations—purely informational retrieval. The use of 'get' and 'list' confirms read-only semantics. Severity is low because unauthorized access to topic listings poses minimal risk to the instance.
From the tool's definition Tool name 'get_virtual_agent_topics' and description 'List Virtual Agent topics available in the instance' indicate a read-only operation that retrieves/lists data without modification or side effects.
