AI agents call nasa_donki to retrieve information from Nasa without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a space weather database to retrieve notifications and information. It is a read-only data retrieval operation with no capability to modify, execute external operations, or cause financial impact. The low severity reflects minimal risk even if an AI agent calls it with any arguments—it only returns space weather data that is already publicly available.
