Shibui Finance

Fundamentals, technicals, and backtests. Just ask. Shibui Finance is a free MCP connector that gives Claude direct access to 64 years of US stock market data. Ask a question in plain English and Claude runs real SQL against the database, then returns verifiable numbers instead of guessing. No API keys, no code, no Bloomberg subscription. What you can do: - Screen 9,900+ NYSE and NASDAQ stocks on fundamentals, valuation, and technicals in a single query - Pull income statement, balance sheet, and cash flow back to 1990, quarterly and annual - Run RSI, MACD, Bollinger Bands, and 50+ other indicators across 31M daily price rows since 1962 - Backtest a signal across decades: "how did stocks move 30, 60, and 90 days after X?" - Compare a company against its sector or a custom peer group - Search 6.4M SEC filing records (10-K, 10-Q, 8-K, Form 4) since 1993 - Export any result table to Excel What makes it different: Most financial connectors wrap a data API, so they can only return what an endpoint hands back. Shibui runs real SQL against the database, with joins, window functions, and multi-quarter trends, so Claude answers questions a plain screener can't. One example, in one question: "Find companies that held positive free cash flow every quarter for five years, then posted their first negative quarter. What did the stock do 30, 60, and 90 days after?" Honest about the data: It's built for screening and research, not live trading. Prices update daily with about a one-day lag. No intraday, no real-time, no options or crypto. NYSE and NASDAQ only. Solid for analysis, not institutional grade. Add the connector at mcp.shibui.finance and ask your first question.
