Get fundamental data for a symbol.
AI agents call fundamentals to retrieve information from Rozkoduj MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches financial metrics (earnings, balance sheet data, ratios, etc.) for a given trading symbol. It is purely informational and read-only, returning pre-computed fundamental analysis without creating, modifying, or deleting data. No code execution, financial transactions, or irreversible actions occur. Low severity because misuse would only expose or deliver existing market data to the AI agent.
From the tool's definition Tool description states 'Get fundamental data for a symbol' — a data retrieval operation with no modification or execution capability.
