Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http finzdata https://api.finzdata.com/mcp --header 'X-API-Key: your-value'

Fill in the empty values before running it.

Open in Cursor

      "headers": {
        "X-API-Key": "your-value"

Common questions

Is FinzData market data safe?

It passed 1 of 1 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?

You need to fill in: X-API-Key

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 18 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 in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, zanadir

FinzData MCP server

Research-grade US market data and server-side backtests for AI agents: Claude, ChatGPT, Gemini CLI, Cursor, Kimi, GLM and any MCP client.

Remote server: https://api.finzdata.com/mcp (Streamable HTTP, MCP 2026-07-28, accepts 2025-06-18 clients) Auth: OAuth 2.1 with PKCE (sign in with your FinzData API key), or the header Authorization: Bearer YOUR_API_KEY Free key: https://finzdata.com/signin · Pricing: https://finzdata.com/pricing · Agent docs: https://api.finzdata.com/agents.md

Coverage

Market data your backtests can trust. The whole market, remembered: every one of the 16,000+ US stocks that has traded on the NYSE and Nasdaq in the last 26+ years, delisted included, point in time. Around them: 139 futures markets with every contract since 2007, the VIX and Cboe volatility indexes with the VIX futures curve, options-market gamma for single stocks, ETFs and the major indexes, 231 ETFs, and crypto since 2015. Macro exactly as it was known: 18,000+ series including CPI, payrolls, wages, GDP and the Treasury yield curve, every vintage kept. Plus COT positioning since 1986. Bars at every resolution you backtest on: 1-minute, 5-minute, 15-minute, 30-minute, hourly and daily, with tick-level trades on the Institutional plan. In pandas with one line: pip install finzdata.

Why FinzData for agents

Survivorship-free. Universes include every company that traded on a date, delisted names included.
Point-in-time. Every data tool takes as_of, so answers contain only what was public that day: fundamentals as filed, and macro series as first published (ALFRED vintages).
Backtests run on the server. Describe a strategy and get back CAGR, volatility, Sharpe, drawdown, turnover, a benchmark, an equity curve, a reproducible run_id and a deflated Sharpe ratio that counts every variant you tried.
