By Fruit Stand Team · September 7, 2026 · Comparisons If you want an LLM to answer questions about how a fund or ETF has performed, an MCP server is the cleanest way to wire live data into the conversation. But most finance MCP servers weren’t built for that question. They hand back prices or holdings, and leave the return math to you. We looked at the finance MCP servers people actually connect for fund data to see which ones publish computed trailing and calendar year returns for funds and ETFs, how many funds and ETFs each covers, whether there’s a free option, and what it costs. This is the MCP counterpart to our earlier writeup, Fund and ETF Returns Data on Snowflake, Compared. Fruit Stand’s own Fund Returns MCP server is included below as one row among the rest.

Fund Returns MCP Server Comparison

Last updated: September 7, 2026 * A free tier exists, but the fund and ETF performance data is gated to a paid plan — Twelve Data’s fund/ETF metrics are on the Ultra plan; Financial Modeling Prep’s ETF and mutual fund holdings are on the Ultimate plan. Pricing key: $ — a free-tier-first plan or entry paid plans under about $50/mo · $$ — roughly $50 to $250/mo for the relevant data · $$$ — $250/mo or more, or enterprise-only, for the relevant data.

​
What this actually shows

Almost none of the popular finance MCP servers are a fund-returns product. Financial Modeling Prep, Alpha Vantage, Financial Datasets, and Polygon.io all expose funds and ETFs in some form — holdings, sector weights, expense ratios, a price series — but none of them publish a computed trailing or calendar year return for a fund. “Fund returns” on those servers means pulling an adjusted price history and doing the CAGR and cumulative math yourself, in the model or in your own code. Three of the four don’t carry mutual funds at all. EODHD is the middle ground. Its ETF fundamentals include a small block of trailing returns (YTD, 1-year, 3-, 5-, and 10-year) alongside volatility and Sharpe ratio, so an MCP client can read those directly. But there’s no year-by-year calendar return breakout, and on the mutual fund side the performance fields are yields rather than total returns. Twelve Data is the closest thing to a direct comparison. Its mutual fund and ETF performance data returns trailing, annual, quarterly, and load-adjusted returns — a genuine computed-returns product, and the only other one here with a year-by-year annual return series. Two caveats: the trailing schedule is shorter (roughly YTD through 10-year, versus Fruit Stand’s sixteen periods out to 20-year and since-inception), and the fund and ETF metrics that carry those returns sit on the Ultra plan, so the free tier and the lower paid tiers won’t answer a fund-returns question. Where a server’s specific coverage counts or return periods aren’t publicly documented, the cells above say “Not published” rather than guess.

​
Where Fruit Stand fits

Fund Returns is built to answer one question well: what has this fund or ETF actually returned. The MCP server exposes six tools — SearchFunds, GetFund, GetTrailingReturns, GetCalendarReturns, BatchTrailingReturns, and BatchCalendarReturns — over roughly 32,000 US mutual funds and ETFs:
  • 16 trailing periods per fund: 1-day, 1-week, 1-, 3-, 6-month, YTD, and 1, 2, 3, 4, 5, 7, 10, 15, 20-year, plus since-inception. Periods of 2 years and up are annualized (CAGR); shorter ones are cumulative.
  • Calendar year returns for every year back to each fund’s own inception, not a fixed shared cutoff.
  • Survivorship-bias-free — delisted funds keep their full return history instead of disappearing.
  • A flat, public price with a real free tier. The $0 plan is 250 requests/month with no card, and the hosted MCP server is included on every plan, authenticated with the same API key as a Bearer token.

F.A.Q.

From each server’s own MCP documentation, API reference, and public pricing pages as of the “Last updated” date above. Where a specific detail — a coverage count, a return period, a price for the relevant data — wasn’t publicly documented, the cell is marked “Not published” rather than estimated.
Twelve Data lists the largest raw universe (80,000+ funds and ETFs, global, split not published). Fruit Stand covers roughly 32,000 US mutual funds and ETFs with full computed trailing and calendar year returns on every one. EODHD publishes 20,000+ US funds and 10,000+ ETFs. Alpha Vantage, Financial Datasets, and Polygon.io don’t cover mutual funds at all.
For getting fund and ETF returns specifically, in most cases yes. Fruit Stand includes the MCP server on a $0 tier and tops out at $129/month. Twelve Data’s fund/ETF performance metrics require the Ultra plan; Financial Modeling Prep’s fund and ETF holdings require the Ultimate plan. EODHD’s fundamentals feed is the nearest comparison on price. Check each provider’s current plans, since the data you need may sit on a higher tier than the headline price suggests.
It can, and for a one-off number that’s fine. Doing it correctly at scale is the hard part: adjusted closes that fold in splits and distributions, the right annualization convention for multi-year windows, partial-period handling for young or delisted funds, and gap handling for thinly traded funds. A returns product does that once, consistently, for every fund. That’s the difference between the “Yes” and “No” rows in the trailing-returns column above.
