Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

backtest
backtest_portfolio
Use this when the user describes a portfolio of US stocks and ETFs with weights (e.g. "60% VTI, 40% BND", "equal parts AAPL, MSFT, NVDA") and wants to know how it would have done or how risky it is: returns over YTD, 1 year and 5 years (rebalanced quarterly), max drawdown, volatility, Sharpe, beta vs SPY, dividend yield and the correlation between holdings, charted against SPY, with a link that opens it on Redstone to save. 2 to 20 holdings. Not for live brokerage accounts, trading or allocation advice.
compare
compare_securities
Use this when the user wants to compare 2 to 5 US stocks or ETFs side by side (e.g. "VOO vs QQQ", "SCHD or VYM?"): returns, drawdown, volatility, Sharpe, beta, dividend yield and how correlated they are, with an overlaid 1Y/5Y chart. End-of-day data for US large and mid caps, major foreign stocks and US ETFs. Not for intraday quotes or recommendations on what to buy.
portfolio
get_portfolio
Use this when the user asks about one public Redstone portfolio, usually a search_portfolios result: its holdings with each one's own figures, its returns over YTD, 1 year and 5 years, max drawdown, volatility, Sharpe, beta and dividend yield, charted against SPY. Not for a portfolio the user describes (use backtest_portfolio) or private portfolios.
portfolios
search_portfolios
Use this when the user wants to see real portfolios to learn from or copy (e.g. "show me low-drawdown dividend portfolios", "portfolios that hold SCHD", "the best risk-adjusted portfolios on Redstone"): the public portfolios Redstone's users built and shared, and Redstone's model portfolios, with past-year returns, risk and yield. Describe the kind of portfolio with the figure filters where one fits; nameIncludes only matches names, so keep it for themes no figure captures, such as "AI". Up to 10 results. Not for the user's own brokerage account or for recommending a portfolio to buy.
screen
screen_securities
Use this when the user wants a ranked list of US stocks or ETFs by a performance, risk or dividend yield metric, optionally within a sector or ETF category (e.g. "lowest volatility dividend ETFs", "highest yielding bond ETFs", "highest Sharpe tech stocks this year", "energy stocks with the smallest drawdown"). Covers about 2,900 US-listed stocks and about 1,200 US ETFs, end-of-day. Not for fundamentals (P/E, revenue), news or buy recommendations.
security
get_security_metrics
Use this when the user asks how a single US stock or ETF has performed or how risky it is: YTD, 1-year and 5-year annualized returns, max drawdown, volatility, Sharpe, Sortino, beta, alpha and dividend yield, with a 1Y/5Y chart. End-of-day data for US large and mid caps, major foreign stocks and US ETFs. Not for intraday quotes, news, earnings, fundamentals or price targets.

Redstone Markets — questions

Answers built from our own checks of this server.

What can Redstone Markets do?
It exposes 6 tools, read directly from the server on our last check. Among them: backtest_portfolio, compare_securities, get_portfolio, get_security_metrics, screen_securities, search_portfolios. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Redstone Markets working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 9 of 91 checks got a reply (9.9%), average response time 328 ms. The bar chart above shows every period we have measured.
The registry lists Redstone Markets as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Redstone Markets?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Redstone Markets need an API key?
No. Redstone Markets completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Redstone Markets?
It answers our handshake in 328 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
