Scored across 22 tools
Most tools have clearly distinct scopes: quotes, history, financials, dividends, news, holdings, analyst data, options, and browse endpoints. Minor overlap exists between get_calendar and get_earnings on upcoming earnings dates, and get_quote/get_quotes are intentionally paired singular/batch tools.
All tools use snake_case with a consistent get_ prefix (get_quote, get_financials, get_sec_filings), except search, which is a bare verb. This is very predictable with one minor deviation.
22 tools is slightly heavy for a typical MCP server, but Yahoo Finance is a broad data domain and each tool maps to a distinct data category or endpoint. The count is reasonable for the scope, though a few granular analyst/ownership tools could potentially be consolidated.
The surface covers quotes, history, fundamentals, dividends, news, calendar, earnings, estimates, recommendations, holders, insider activity, SEC filings, options, fund data, sector/industry browsing, market status, and search. Peripheral gaps like screeners or market movers are minor and do not block core workflows.
