About Stocklake
Stocklake gives AI assistants, and the people who use them, stock market data through MCP (Model Context Protocol). Ask in plain language; the assistant fetches prices, fundamentals, filings and news from Stocklake and answers from them.
What it is
An MCP server with 20 tools that any MCP-capable assistant can connect to, plus a website with a search page and a page for every covered stock. 11 of the tools work without paying; 9 are part of the Pro plan. The tool reference lists every tool and what it returns, and the docs show how to connect.
Stocklake is a data and research tool. It does not hold money, place orders or manage a portfolio.
What it covers
- More than 3,400 stocks in more than 50 countries (about 2,000 US-listed companies, the rest listed elsewhere), and more than 300 ETFs.
- For each stock: price and volume, daily price history, fundamentals and financial statements, technical indicators, news, insider transactions, institutional holders, analyst ratings and price targets, and earnings dates. ETFs have prices, history and indicators, but no statements.
- For the market as a whole: index and volatility readings, breadth, an economic calendar, and a read on the overall market and on each of 11 sectors.
Insider transactions come from regulatory filings: SEC filings (Form 4) for US companies, and the BaFin, AFM and CNMV registers for Germany, the Netherlands and Spain. Prices, fundamentals and news come from third-party market data and news feeds.
How the numbers are built
- Technical indicators (RSI, MACD, Bollinger Bands, moving averages, ATR and others) are computed from daily price history with the standard published formulas.
- signal_score is one 0-100 number for each signal. It mainly measures how stretched the stock is in the signal's direction: a long signal scores higher when the stock looks oversold, a short one when it looks overbought. A few setups also count the longer-term trend. A news article with no signal behind it, or an insider read, is scored from the AI's read instead. How it works.
- macro_score and sector_score are the 0-100 numbers behind the market and sector labels, half computed from market data and half from an AI read. How they work.
- Forensic accounting scores apply three published formulas (Altman Z, Piotroski F, Beneish M) to each company's filed statements. We did not invent or tune them. What they can and cannot tell you.
- Summaries, news reads and signals are written by scheduled AI pipelines, not when you ask. The result is the same for every caller and fast to fetch, and it can be wrong. Treat it as a starting point and check the numbers next to it.
How fresh the data is
- Prices
- Refreshed about every 10 minutes on trading days, less often at weekends. Quotes are delayed, typically by about 15 minutes, so a price is never a current quote.
- Daily history
- One bar per trading day.
- Technical indicators
- About every 4 hours on weekdays.
- News
- Added through the day.
- AI summaries
- Each stock is rewritten every few days; the response says when.
- Market and sector reads
- About 4 times per weekday during market hours; not overnight or at weekends.
- Insider and institutional data
- Scanned daily; a stock updates when new filings appear.
- Statements and forensic scores
- When a company files new statements.
Responses carry timestamps such as updated_at and generated_at. Check them before relying on a figure.
What it cannot do
- No intraday bars, tick data, options or order books.
- No order execution.
- Indices, futures and currency pairs cannot be looked up by symbol; the market overview carries the main index and volatility readings.
- Regulatory insider filings are covered for the US, Germany, the Netherlands and Spain only. Elsewhere, insider data comes from market data where it exists, and many stocks have none.
- Non-US listings need the exchange suffix, for example SAP.DE.
- Scores describe what the data shows now. They do not predict prices, and a high or low score is not a reason to buy or sell.
No advice
Market data and research context for informational purposes. Not investment advice. Stocklake does not tell you what to buy or sell and does not make trade calls. Signals point at situations worth a look; they are not recommendations. The legal page has the full terms.
