Connects Claude to Yahoo Finance's market data APIs with four core operations: search for tickers, pull real-time quotes, fetch historical price charts, and grab detailed quote summaries. You'd reach for this when building financial analysis workflows, portfolio trackers, or investment research assistants that need live market data without wrestling with Yahoo Finance's undocumented endpoints yourself. The uptime sits at 100% over the past month with sub-200ms latency, and it's seeing decent usage from both Claude desktop and web clients. If you're tired of manually looking up stock prices or scraping financial data, this handles the plumbing so your agent can just ask for AAPL's latest quote or chart AMD's six-month performance.
