Best MCP servers for market data

Financial questions need live numbers: a stock's current price, a crypto quote, a company's fundamentals, historical series for a backtest. An agent with market-data tools can pull those figures on demand instead of relying on the model's stale, training-cutoff knowledge, which is dangerous for anything price-sensitive. The right server depends on the asset class and depth you need: crypto pricing, traditional equities and FX, free historical market data, or comprehensive fundamentals. The recurring need is the same, give the agent access to current, real market data. The servers below are real MCP servers with current, verified install configs.
