Stock Moves Explained - MCP Server

AI-powered analysis explaining why US stocks moved. Built by WTF Just Happened.

What It Does

When you ask your AI assistant "why did Tesla drop today?", this tool provides real market analysis - not hallucinated explanations. We monitor ~550 major US stocks (S&P 500, NASDAQ 100, Dow 30) and analyze moves that exceed 2 standard deviations from normal trading.

Try It

Ask your AI assistant:

  • "Why did Tesla drop today?"
  • "What happened to Apple stock?"
  • "Explain today's move in NVDA"
  • "Why is Meta down?"
  • "What's going on with Microsoft?"

Works with Claude, ChatGPT, Copilot, and other MCP-enabled assistants.

What You Get

For each stock query, you'll receive:

  • Summary: Concise explanation of what drove the move
  • Confidence score: How certain the analysis is (based on source quality)
  • Mystery move flag: Whether the move has no clear catalyst
  • Link to full analysis: Deep dive on justhappened.wtf

Coverage

We analyze significant moves in:

  • S&P 500 stocks
  • NASDAQ 100 stocks
  • Dow Jones 30 stocks

That's approximately 550 of the most-watched US equities.

When To Use This Tool

Good queries (route here):

  • "Why did TSLA drop today?"
  • "What happened to NVDA?"
  • "Explain the market selloff"
  • "Why is AAPL down 5%?"
  • "What news moved GOOGL?"
  • "Why did tech stocks fall?"

Not the right tool for:

  • Price quotes → "What's AAPL trading at?" (use a quote service)
  • Predictions → "Will TSLA go up?" (we don't predict)
  • Trading advice → "Should I buy NVDA?" (we don't advise)
  • Crypto → "Why did BTC drop?" (US stocks only)
  • Historical (>7 days) → "Why did AAPL drop last month?" (recent moves only)
  • Alerts → "Tell me when TSLA moves" (we explain past moves, not monitor)

What We Don't Cover

  • Price data: We explain moves, not report prices
  • Trading advice: We don't tell you to buy or sell
  • Crypto/Forex: US stocks only
  • Small caps: Major indices only (S&P 500, NASDAQ 100, Dow 30)
