How do I connect ChatGPT to free stock market data?

Add canli-mcp's free hosted server as a connector in ChatGPT, at https://canlicapital.com/mcp/canli. It needs no API key, and ChatGPT can then read prices, SEC filings and economic data. Custom connectors depend on your ChatGPT plan and settings, so check yours first.

The tools behind the answer

From canli-mcp's tool index
ToolPackWhat it does
price_historymarketsPrice bars (open, high, low, close, volume), daily to hourly, for US stocks and ETFs, stocks listed abroad (SAP.DE, 7203.T), currency pairs (EUR/USD), futures (crude oil, gold), indices and yields (S&P 500, VIX, 10 year yield) and crypto (bitcoin), by symbol or plain name. Stocks adjust for splits and dividends by default, with dividends, splits and the total return; returns: true adds daily returns.
