What it does

An MCP server that bridges Claude to Yahoo Finance market data. Provides tools to fetch company fundamentals, financial statements (income, balance sheet, cash flow), recent news, sector rankings, and historical price data with adjustable time periods and granularity. Can generate technical analysis charts (candlestick with volume, VWAP, volume profile) as WebP images, perform searches across quotes and news, and retrieve options chains and insider ownership information. All data returns as structured JSON or markdown tables.

Who it's for

Finance analysts, equity researchers, investment advisors, and professionals building financial research workflows. Useful for anyone who wants to pull real-time and historical market data into Claude conversations without context switching or manual lookups.

Common use cases

Query company fundamentals and valuation metrics for a stock ticker
Generate candlestick or technical analysis charts over custom time periods
Search Yahoo Finance for stocks, ETFs, and news by keyword
Fetch quarterly and annual financial statements for due diligence
Rank sectors and identify top performers or growth companies

Setup pitfalls

yfinance dependency — ensure the package is installed alongside the MCP server
Intraday data requests (e.g., interval="1m") may hit rate limits; batch requests when querying many tickers
Chart generation returns base64-encoded WebP images for token efficiency — requires a client capable of decoding them
