Get weather alerts for a US state.
AI agents call get_alerts to retrieve information from Weather Alerts MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves real-time weather alert data from an external API with no side effects. It does not modify state, execute code, delete data, or involve financial transactions. The severity is low because misuse would only result in retrieving potentially unnecessary weather information, with no harmful consequences.
From the tool's definition The tool description states it retrieves 'weather alerts from the National Weather Service API' and 'Provides formatted weather warnings, watches, and advisories' without any modification, creation, deletion, or execution capabilities.
