Then just ask your assistant something like “Analyze AAPL with Stoxly” or “Compare VOO and QQQ fundamentals” — it will call the tools below automatically.

Tools

`analyze_stock`

Fundamental analysis of any publicly traded stock. Returns the 10-point score, a descriptive verdict, per-criterion checks (P/E, PEG, price/book, revenue growth, ROE, operating margin, return on assets, quick ratio, debt/equity, free cash flow yield), every metric value and the link to the full analysis page. null means a metric was unavailable — it is never treated as 0.

symbolstring · required

Ticker in Yahoo Finance format, e.g. AAPL, BRK-B, SAP.DE.

`analyze_etf`

Analysis of an ETF (US-listed funds have the most complete data). Returns the 10-point score, verdict and checks covering expense ratio, fund size and age, holdings, concentration, volatility and 1/3/5-year returns.

symbolstring · required

ETF ticker, e.g. VOO, QQQ, SCHD.

Plain JSON API

The same analysis is available as a single JSON request — useful for scripts or non-MCP integrations, with the same 30-requests-per-hour limit:

Request

curl "https://www.stoxlyonline.com/api/stock/analysis?symbol=AAPL"

Response (truncated)

      "quickRatio": 0.86,
      "debtToEquityRatio": 1.35,
      "freeCashFlowYield": 0
    }
  }
}

Note: in this raw endpoint a ratio value of 0 means “not available”; the MCP tools return null for unavailable metrics instead.

Scoring thresholds and data sources are documented on the methodology page and in llms-full.txt.

Frequently asked questions

What is the Stoxly MCP server?+

It is a remote server implementing the Model Context Protocol (MCP), the open standard AI assistants like Claude, ChatGPT and Cursor use to call external tools. Once connected, your AI assistant can run Stoxly analyses itself: ask it about any stock or ETF and it fetches the 10-point score, verdict and all underlying metrics directly from Stoxly.

Is the MCP server free and do I need an API key?+

Yes, it is free, and no API key or account is required. Usage is rate-limited to 30 tool calls per IP per hour, which is plenty for personal research and watchlists. The same data is also available as a plain JSON endpoint with the same limit.

Which stocks and ETFs are supported?+

Any symbol Stoxly itself supports, in Yahoo Finance ticker format: US listings (AAPL, BRK-B), European listings (SAP.DE, ASML.AS) and Asian listings including Hong Kong/China. ETF fund statistics are most complete for US-listed ETFs such as VOO or QQQ; European ETF listings often return partial data.
