What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

  • compare_assets

    Compare 2 to 10 market symbols using the same normalized mkts snapshot. Returns requested and resolved symbols plus normalized asset records with provenance metadata.

  • get_archive_series

    Get what mkts recorded for up to 100 symbols on every day in a date range, from the immutable point-in-time archive. This is the shape a portfolio backtest actually needs — N symbols by M days in one call, where get_asset_series would take one call per holding and get_assets_as_o

  • get_asset_intraday

    Get every price observation mkts made of one symbol inside a time window, rather than just the daily close. Use for intraday movement, timing questions, or checking what a price was doing during a session; use get_asset_series instead for daily closes over months. Cadence is not

  • get_asset_profile

    Look up one asset by symbol and return what it is and where it stands: name, asset type, price, 24h percent change, market cap, 24h volume, sector for stocks and ETFs, supply figures for crypto, and when it was last observed. Served from the mkts snapshot, which refreshes about e

  • get_asset_quote

    Get a current quote for a stock, ETF, cryptocurrency, commodity, or forex pair. Returns price fields, market state when available, an observation timestamp, and upstream source.

  • get_asset_series

    Get what mkts recorded for one symbol on every day in a date range, from the immutable point-in-time archive. Use this for backtesting rather than calling get_assets_as_of once per day — a 90-day study is one call here and 90 there. Distinct from get_price_history, which fetches

  • get_assets_as_of

    Get what mkts recorded about one or more symbols on a specific past date, from the immutable point-in-time archive. Pass a single symbol or up to 100. Use for backtesting, reconstructing a past decision, or checking whether a figure was later revised — not for current prices, whi

  • get_assets_bulk

    Get current data for an explicit list of up to 100 symbols in a single call. Use this instead of calling get_asset_quote repeatedly — a watchlist fetched one symbol at a time exhausts the rate limit for no benefit. Returns the resolved assets plus unresolvedSymbols naming anythin

  • get_filings

    List recent SEC filings for a US-listed company or fund, newest first, from SEC EDGAR. Each filing has its date, form type, a plain-language title (for 8-Ks, the events reported), the period it covers, and links to the EDGAR index page and the main document. Use to find the lates

  • get_fundamentals

    Get annual or quarterly financial-statement time series for a stock: income statement, balance sheet and cash flow, built from the company's own SEC filings (source "sec-edgar"), or from the equities provider for funds and companies EDGAR does not cover. Values are in the reporti

  • get_macro_snapshot

    Get the current mkts macro dashboard, including major equity proxies, crypto, commodities, the US dollar, volatility, and the US 10-year yield.

  • get_market_snapshot

    Get the current global cryptocurrency market totals, volume, dominance, active asset counts, and the underlying snapshot timestamp.

  • get_news

    Get recent market news from the configured source feeds. Filter by an asset symbol or by markets, crypto, commodities, or forex category. Returns source and publication links.

  • get_price_history

    Get bounded daily price history for a symbol. Stocks and ETFs include OHLCV when available; cryptocurrency history may contain close and volume only.

  • screen_assets

    Find assets matching price, daily-move, volume, market-cap, asset-type and sector filters, sorted as requested. Use for questions like "biggest movers today", "tech stocks over $1T" or "cheapest crypto by price"; all filters are optional and combine with AND. Covers the whole mkt

Common questions

Is mkts Market Data safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 15 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
