Выставить биржевую заявку в Т-Инвестициях
AI agents use post_order to commit financial operations through T-Invest MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Placing a stock exchange order directly commits financial obligations by buying or selling securities at market or specified prices. This is a financial operation with potentially large monetary impact if misused by an AI agent, warranting the highest severity classification.
From the tool's definition 'Выставить биржевую заявку' means 'Place a stock exchange order' in Russian; the server description explicitly mentions 'executing trading operations, including placing and canceling market or stop orders'
