AI agents call get_tagged_elements to retrieve information from Postman without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data (tagged elements) from the Postman API collection without modifying, deleting, or executing any operations. The verb 'get' and the read-only nature of filtering by tags confirm this is a Read operation with minimal risk.
From the tool's definition Tool name 'get_tagged_elements' and description 'Get elements by tag' indicate a retrieval operation with no side effects.
