Short answer
Most stock market MCP servers only read data. The ones that can place orders are Alpaca (US stocks and options at a regulated broker, with paper trading), OpenFinance (onchain stocks and stock perps with no KYC, plus crypto and prediction markets in the same connection), and Interactive Brokers integrations. Data-only servers such as Financial Datasets or Alpha Vantage cannot trade.
