Returns the monthly unemployment data of the United States
AI agents call get_unemployment to retrieve information from AlphaVantage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries public unemployment statistics from the US, which is a read-only operation. There is no data modification, code execution, deletion, or financial transaction involved. The tool simply fetches and returns existing data, fitting the Read category. Severity is low because misuse would only result in unnecessary API calls or data retrieval, with no harmful consequences.
From the tool's definition Tool name 'get_unemployment' and description 'Returns the monthly unemployment data' indicate a retrieval operation with no modification or side effects. The data returned is publicly available economic statistics.
