Fetches earnings data (annual/quarterly). Premium endpoint.
AI agents call fundamentalData_earnings to retrieve information from MCP Avantage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical earnings information from the Alpha Vantage API without creating, modifying, deleting, or executing any operations. Despite being a premium endpoint, it poses minimal risk as an AI agent cannot misuse it to harm systems or data—it merely queries existing financial data. Classified as Read with low severity.
