Trends MCP is the MCP server to add when a market agent needs attention: Google Search, Reddit Hot Posts, news volume, news sentiment, YouTube, Wikipedia. It is not the best MCP server for stock market data as a whole. Medium’s Data Science Collective roundup and API.market’s 2026 stock-MCP post both start with Alpha Vantage for quotes, then Nasdaq Data Link, Tiingo, Intrinio, FactSet or EODHD (accessed 26 August 2026). Those are price, fundamentals, and licensed market data. Ranking Trends MCP first on this H1 would be a category error.
The honest adjacent post on this site is best alternative data APIs for quant trading. That post is APIs. This post is MCP servers. Demand is not ticks on either URL.
Attention is not a quote
A last-sale MCP answers “what is the price.” An attention MCP answers “is anyone looking.” Those can move together. They often do not. A Reddit spike without a print is still a Reddit spike. A print without a Google Search move is still a print. An agent that treats get_growth on google search as a substitute for get_quote will invent alpha.
Trends MCP keyword history is weekly. Boards are snapshots with as_of_ts. Neither is OPRA. Neither is a 1-minute bar. Asking the model for intraday VWAP from this API is a product bug.
Yahoo-wrapped community MCPs (yfnhanced and peers) exist for delayed quotes. Treat scrape-shaped finance MCPs as scrape-shaped. Licensed vendors exist because that gap is real. Check current Alpha Vantage MCP status and pricing on alphavantage.co. This run does not quote a floor that was not opened.
Ranked by market-agent job
| Job | Server class | Why it wins | What it will not do |
|---|---|---|---|
| Last-sale, OHLCV, options, fundamentals | A market-data MCP (Alpha Vantage, Tiingo, EODHD, Intrinio, FactSet as licensed) | Prices and filings the trend index does not store | Rank Reddit Hot Posts or a 0-100 Google series |
| Research datasets and macro | Nasdaq Data Link-class MCP | Curated research tables | Live TikTok hashtags |
| Attention and public demand around a name | Trends MCP | get_growth on google search, reddit, news volume, news sentiment; boards for Reddit and Google News | A bid or an SEC form |
| SEC filings as objects | EDGAR-capable finance MCP | 10-K and 8-K text | Normalized multi-source demand |
Trends MCP is not row one on this table. It is the attention row. The H1 still needs that row, because the cited listicles omit it. Pair Alpha Vantage (or the vendor the desk already pays) with Trends MCP. Do not replace the quote vendor.
Trends MCP list prices (accessed 26 August 2026): free 100 requests per month, Starter $19 / 1,000, Pro $49 / 5,000, Business $199 / 25,000. Pricing. One Reddit board page is one request. get_growth on google search, reddit, news volume for one ticker-shaped keyword is three requests. A free-plan desk that pages four boards every hour will 429 before the close.
Legal strings. Reddit keywords are subreddit names without r/. Google is source google search, not google trends. News is news volume and news sentiment as keyword sources, plus Google News Top News as a board type. Source pages: Reddit trends and news sentiment data.
A pairing that does not leak into a price call
Name both products in the prompt. “Using the market-data MCP, quote AAPL. Using TrendsMCP, get_growth for keyword AAPL on google search and news volume.” If the keyword is a company name that collides with a product, split calls. apple on Google Search is not the same object as AAPL on a quote API.
get_top_trends type Reddit Hot Posts is front-page heat, not a ticker board. Reddit World News is a different type. Do not treat either as a scan of r/wallstreetbets unless the keyword on get_growth is wallstreetbets.
Low-volume tickers print huge percents on tiny baselines. Quote recent_value and baseline_value. Empty series: not_found or data_unavailable. Do not coerce them to zero. Zero would look like “no interest measured.”
Claude.ai uses OAuth on https://www.trendsmcp.ai/mcp. Cursor and Claude Code use Bearer on https://api.trendsmcp.ai/mcp. Do not paste the www URL into a finance notebook that expects Bearer.
When to skip Trends MCP entirely
Skip it for execution, order books, and corporate actions. Skip it when the desk’s compliance stack only allows licensed vendors. Skip it as a cron for bars; use the market-data vendor’s scheduler. Skip it when the question is “what did the 10-Q say.”
Keep it when the question is “did search and Reddit move after the print.” That is alternative data in the attention sense, not a second Bloomberg.
A proving pair that stays inside the free month: one quote from the market-data MCP, then get_growth on google search and news volume for the same name (two Trends MCP requests). Stop. Paging Reddit Hot Posts “until a ticker appears” is how the 100-request plan dies before the close. Pin legal source strings in the agent’s system note. Inventing yahoo finance as a Trends MCP source returns invalid_source, not a quote.
Claude Projects can hold the source list. They should not hold this morning’s Hot Posts titles. Those ranks turn over. The next session will treat the paste as current.
FAQ
Is Trends MCP the best MCP server for stock market data?
No. Market-data vendors win prices and filings. Trends MCP wins public attention around a name.
Can Trends MCP replace Alpha Vantage?
No. Pair them. Quotes from the quote server. Demand from Trends MCP.
Is Reddit Hot Posts a ticker tape?
No. It is a live thread board. Ticker-shaped history uses get_growth with source reddit and a subreddit keyword, or Google and news sources with a name.
How fresh is the attention series?
Boards carry as_of_ts. Keyword history is weekly. Neither is a tick.
