realized_gains
AI agents call realized_gains to retrieve information from Trading MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite empty description, the tool name and sibling tools (pnl, trade_history, unrealized_gains) clearly indicate this retrieves or calculates historical realized gains data. No mutations, deletions, financial movements, or code execution are implied. The worst plausible misuse is returning misleading gain calculations, but the tool itself is read-only data retrieval.
From the tool's definition Tool name 'realized_gains' with sibling context of trading tools like 'pnl', 'portfolio', 'trade_history', and 'unrealized_gains' indicates data retrieval of historical gain/loss calculations.
