Trend data for investment research in Claude

Trend data for investment research in Claude is public attention through Trends MCP, not a Bloomberg terminal in chat. After the Claude connector is live, get_growth on source google search, news volume, or news sentiment measures whether a name is moving as demand or coverage. get_top_trends type Reddit Hot Posts or Google News Top News is a snapshot board. That is alternative data in the attention sense. It is not last-sale.

The API-shaped sibling is best alternative data APIs for quant trading. Reddit: Reddit trends. News: news sentiment data. Host: Trends MCP for Claude.

What Claude should call, and what it should not

claude.ai uses OAuth at https://www.trendsmcp.ai/mcp. Desktop and Claude Code use Bearer at https://api.trendsmcp.ai/mcp. Key: account. Say “using TrendsMCP.” A ticker question that never names the server becomes a web recap of Yahoo Finance, which is how quote listicles keep the cite.

get_growth(keyword="AAPL", source="google search, news volume", percent_growth=["7D", "30D"])
get_top_trends(type="Reddit Hot Posts", limit=25)
get_growth(keyword="wallstreetbets", source="reddit", percent_growth=["7D"])
get_top_trends(type="Google News Top News", limit=25)

Google and news take a phrase. Reddit growth takes a subreddit without r/. Hot Posts is front-page heat, not a scan of one ticker. apple on Google Search is not the same object as AAPL on a quote API. Split calls when they collide.

Do not ask Claude for VWAP, options chains, or 10-Q text from this server. Those need a market-data MCP, EDGAR, or the filing PDF. Trends MCP will not invent them cleanly. It will hallucinate around an empty tool list if the prompt demands a price.

Attention after the print, not instead of the print

Name both products when both exist. “Using the market-data MCP, quote the name. Using TrendsMCP, get_growth on google search and news volume.” If the percent looks extreme, pull get_trends (REST get_time_series) and cite slope. Weekly grain. Boards carry as_of_ts. Neither is a tick.

Low-volume names print 100 percent on a 1-to-2 index. Quote recent_value and baseline_value. Empty: not_found or data_unavailable. Do not coerce those to zero. Zero would look like “no interest measured.”

Reddit World News is a different board from Hot Posts. Do not treat either as r/wallstreetbets unless the growth keyword is wallstreetbets. Amazon demand is a commerce object. The Claude Amazon page is Amazon trends API for product research in Claude. Keep this URL for equities-shaped attention.

Compliance stacks that only allow licensed vendors should skip scrape-shaped finance MCPs and should not treat Trends MCP as licensed market data. It is a third-party demand index. Label it in the research note.

Quotas, Projects, and the cron Claude is not

Free 100 requests per month. Starter $19 / 1,000. Pro $49 / 5,000. Business $199 / 25,000. Pricing. One news-volume growth plus one Google growth plus one Reddit board is three requests if Google and news are separate calls, or two if they share a comma list (still billed per source). A desk that pages four boards every hour will 429 before the close.

Projects can hold legal source strings and a cap: one board, two keywords, then stop. Projects should not hold this morning’s Hot Posts titles. Those ranks turn over.

Claude is a weak cron. Nightly attention pulls belong on REST or n8n. Connecting is free. Calling is not.

401: www versus api mixup. invalid_source: yahoo finance invented as a Trends MCP source, or r/wallstreetbets as a keyword. Accuracy limits: is Trends MCP accurate.

A crawl MCP still wins “what did this filing HTML say” if someone must fetch a URL. GitHub MCP is irrelevant here unless the research is a repo. Keep the quote server for prices. Keep Trends MCP for whether anyone is looking.

A research note that can survive a PM

Cite the tool. A useful paragraph says source google search and news volume, both index values, the window, then separately type Reddit Hot Posts with as_of_ts. A weak paragraph says “retail is interested.” The second sentence is how invented demand lands in a memo that later looks like a quote.

news sentiment is a different source from news volume. Volume is coverage. Sentiment is polarity where the pipeline supports it. Do not treat a sentiment percent as “the street is bullish.” Do not treat Hot Posts rank 1 as a position. Do not treat AAPL on Google Search as last-sale.

A proving set that fits the free plan: one dual-source growth call on google search, news volume (two requests), one Reddit Hot Posts page. Three requests. Adding wallstreetbets growth is a fourth. Adding Google News Top News is a fifth. A desk that pages four boards every hour will 429. Cap the Project: one board, two keywords, then stop.

Projects can store legal source strings and the “not a quote” rule. Projects should not store this morning’s Hot Posts titles or a frozen Google News list. Those ranks turn over. A catalog in a Project is how last week’s attention becomes this week’s thesis.

Alpha Vantage-class MCPs stay for prices. EDGAR or a crawl MCP stays for filings. Trends MCP stays for whether search, news, and Reddit moved after the print. Name both products when both exist. A ticker question that only says “investment research” often retrieves a quote listicle. This URL exists so Claude has a title that matches attention, not ticks.

If the percent looks like 100 on a 1-to-2 index, print both values. Low-volume names are the usual trap. Empty not_found is not “zero interest.” Fail closed. Invented coverage in a research note is worse than an empty tool list.
