@Marketstack show me the latest end-of-day data for AAPL, MSFT, and GOOGL with their closing prices and volume

Here's the latest end-of-day data for those three tickers: AAPL closed at $178.45 (+1.2%) with volume of 52.3M shares. High: $179.12, Low: $176.88. MSFT closed at $412.67 (-0.4%) with volume of 28.1M shares. High: $415.23, Low: $411.05. GOOGL closed at $141.23 (+0.8%) with volume of 31.7M shares. High: $142.01, Low: $140.15. All data reflects the most recent trading session. Adjusted close values account for splits and dividends.

This example demonstrates the Get End-of-Day Data tool's ability to fetch multiple tickers in one request. Note that Marketstack's free tier limits historical data access and API call volume—check your plan's rate limits before building automated workflows that poll frequently.

@Marketstack get dividend history for AAPL over the last 12 months and calculate the total annual yield

AAPL dividend history (last 12 months): • Feb 2024: $0.24 per share • Nov 2023: $0.24 per share • Aug 2023: $0.24 per share • May 2023: $0.24 per share Total annual dividends: $0.96 per share. Based on the current price of $178.45, the trailing dividend yield is approximately 0.54%. Note: This calculation uses the most recent closing price. Actual yield varies with stock price movements.

This example pairs the Get Dividends tool with AI reasoning to compute yield. Marketstack returns raw dividend records—the AI synthesizes them into actionable insight. Requires a paid plan for full historical dividend access; free tier may return limited results.

@Marketstack look up the exchange info for NASDAQ (MIC: XNAS) and tell me what sectors are most represented there

NASDAQ (XNAS) is a US-based electronic stock exchange located in New York. It operates Monday-Friday, 9:30 AM - 4:00 PM ET, and is one of the world's largest exchanges by market capitalization. While Marketstack provides exchange metadata (timezone, currency, operating hours), it doesn't directly aggregate sector representation. However, NASDAQ is historically dominated by Technology, Consumer Discretionary, and Healthcare sectors—companies like AAPL, MSFT, AMZN, and TSLA trade here. For sector breakdowns, you'd need to query individual ticker data and aggregate by industry classification.

This example shows the Get Exchange Info tool's scope: it returns exchange-level metadata, not aggregate analytics. The AI correctly identifies what the tool can and cannot do. If you need sector distribution analysis, you'll need to fetch ticker info for multiple symbols and aggregate manually.

When Marketstack beats spreadsheet chaos for small syndicates

A 6-person angel syndicate reviews portfolio performance every Monday morning. They track 20-30 early-stage companies that went public, plus a handful of index benchmarks. Before Marketstack, someone manually pulled Yahoo Finance CSVs and pasted them into a shared Google Sheet. Now they run Get Ticker EOD Data and Get Dividends in a Switchy workspace, compare week-over-week closes, and flag outliers in under 5 minutes. The API key auth means no OAuth dance, and the 10 tools cover splits, dividends, and exchange metadata without custom scraping. If your syndicate tracks more than 50 tickers or needs intraday data, you'll hit rate limits on the free tier and need to upgrade. For weekly cadence and public-market tracking, this MCP is the fastest path from 'someone do the spreadsheet' to 'AI does the spreadsheet.'

Why this MCP wins for stock-data troubleshooting at scale

A 12-person fintech startup offers a robo-advisor app. Support tickets often ask 'why did my portfolio value drop?' or 'where's my dividend?' The support team used to manually check Marketstack's web dashboard, then copy-paste explanations into Zendesk. Now they pipe the ticket into a Switchy workspace, run Get Ticker EOD Latest and Get Stock Splits, and the AI drafts a response citing the actual split factor or dividend date. The Get Exchange Info tool catches edge cases where a foreign exchange was closed for a holiday. This works because the MCP's 10 tools map directly to the top 5 support question types, and API key auth means no per-agent provisioning. If your ticket volume exceeds 200/day, you'll need a paid Marketstack plan to avoid throttling. For early-stage support teams, this MCP turns stock-data questions into 30-second resolutions instead of 10-minute rabbit holes.

When Marketstack is overkill for internal financial reporting

A fractional CFO serves 4 SaaS companies and needs to pull public-market comps for board decks each quarter. She compares her clients' revenue multiples to 10-15 publicly traded peers. Marketstack's Get End-of-Day Data and Get Ticker Info tools can fetch the raw OHLCV and sector metadata, but the MCP doesn't calculate valuation multiples or normalize fiscal calendars—she still needs a spreadsheet or BI tool for that. If she's already paying for a Bloomberg Terminal or FactSet seat, Marketstack is redundant. But if she's bootstrapping and only needs quarterly snapshots, the free tier (100 requests/month) covers 4 quarters of 15-ticker pulls with room to spare. The buying call: use this MCP if you're doing lightweight public-market research without a dedicated data vendor, and you're comfortable doing the valuation math yourself.
