QuantGPT vs the EODHD MCP server
UPDATED SEPTEMBER 22, 2026 · WRITTEN BY QUANTGPT, SO READ IT KNOWING THAT
// THE SHORT VERSION
Both plug into Claude, ChatGPT and Cursor over MCP. They do different jobs. The EODHD server is a data pipe: 72 read-only tools that fetch prices, fundamentals, news, options and macro into your AI's context. QuantGPT is an engine: your AI sends a question, the computation runs on our side against decades of market history, and the answer comes back with the numbers that produced it.
If you want your AI to look something up, EODHD is a good choice and it has a free tier. If you want your AI to find out what would have happened, that is what QuantGPT is for.
// SIDE BY SIDE
| EODHD MCP | QUANTGPT MCP | |
|---|---|---|
| What a tool call does | Fetches rows: prices, fundamentals, news, technicals, options, macro, calendars. | Runs a computation: a backtest, a parameter sweep, an event study, a stock grade, a screen, bounded SQL across the warehouse, a branded chart. |
| Where the analysis happens | Inside your AI's context window, on whatever rows fit. | On our side, over the whole history. Your AI receives the result. |
| History | Long end-of-day history across many exchanges. | Decades of US equities, companies that later delisted priced from 1998, fundamentals joined by filing date. |
| Markets | Global: 60+ exchanges, forex, crypto, live quotes, US options chains, news and sentiment. | US equities in depth, plus crypto, commodities, FRED macro, prediction markets and weather. No live quotes, no news feed. |
| Checking the work | You check the math your AI did. | Every result ships with the numbers behind it, and the underlying data can be checked at the public verify page. |
| Price | Free tier (20 calls a day), paid plans from about $20 a month. | A free plan with a handful of backtests; paid plans for the full engine. |
// WHERE EODHD WINS
Coverage. If your question is about a stock listed in Tokyo, a currency pair, today's headlines, or a live quote, EODHD has it and we do not. Their free tier also makes it the cheapest way to give an AI real market data. We would rather say that here than have you find it out after signing up.
// WHERE QUANTGPT WINS
Anything that needs more history than a context window can hold. A question like what did the market do in the year after breadth went weak while ten stocks held a record share of the index touches decades of monthly data across thousands of companies. No AI can pull that through a fetch tool and compute it in its head. On QuantGPT it is one call, and the delisted companies are in the answer because we never threw them away.
Survivorship matters more than it sounds. A backtest run only on the companies that exist today quietly deletes every loser, and the result looks better than anything anyone could actually have earned.
// USING BOTH
They do not compete for the same slot. Plenty of people will connect both: EODHD for lookups and global coverage, QuantGPT for research and backtests. Your AI will pick the right one for each question.
