stock-scanner

stock-scanner-mcp

A modular MCP server for Claude Code and Claude Desktop that provides real-time access to stock and crypto market data. Scan markets, check technicals, monitor insider trades, track earnings, analyze options flow, and optionally save your own watchlists and thesis notes from one server.

65 tools across 13 modules — 9 modules work with zero API keys, including an optional stateful Market Workspace.

Quick Start

Three steps to get the full experience: server config, trading skills, and workspace setup.

Step 1 — Add the server to your MCP config

Copy this complete config block into your config file:

• Claude Code: ~/.claude.json (global) or .mcp.json (project-local)
• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "stock-scanner": {
      "command": "npx",
      "args": ["-y", "stock-scanner-mcp", "--enable-workspace"],
      "env": {
        "FINNHUB_API_KEY": "your-key-here",
        "ALPHA_VANTAGE_API_KEY": "your-key-here",
        "FRED_API_KEY": "your-key-here"
      }
    }
  }
}

This gives you 46 tools immediately with no API keys. API keys are optional and free — they unlock 18 additional tools for real-time quotes, news, earnings, and economic data. See API Keys below for where to get them.

Minimal config — if you don't want workspace or API keys, use this instead:

{
  "mcpServers": {
    "stock-scanner": {
      "command": "npx",
      "args": ["-y", "stock-scanner-mcp"]
    }
  }
}

This gives you 39 stateless tools with no local data storage.

Restart Claude Desktop after saving. Claude Code picks up the config automatically.

Step 2 — Install the trading skills

Run this command in your terminal:

npx -p stock-scanner-mcp stock-scanner-install-skills

This installs 19 slash commands (like /morning-briefing, /analyze-stock AAPL, /setup-market-workspace) into ~/.claude/skills/ so they're available in every Claude Code session. See Trading Skills for the full list.

Step 3 — Set up your workspace

Run /setup-market-workspace in Claude Code. It asks three quick questions:

> /setup-market-workspace

Setting up your market workspace — I'll ask a few quick questions to get started...

1. What kind of trader or investor are you?
   (e.g., options trader, swing trader, long-term investor, crypto-focused)

   → "I'm mostly a swing trader, also watch crypto"

2. Which names or assets should I save to your core watchlist?
   (e.g., AAPL, MARA, BTC, Gold)

   → "MARA, HOOD, SOFI, BTC, ETH"

3. Do you want a daily or weekly market review?

   → "Daily"

Once answered, it saves your profile and creates a core watchlist:

✓ Workspace saved

  Profile     swing trader | daily review
  Watchlist   core — MARA, HOOD, SOFI, BTC, ETH

You can also skip the skill and ask Claude directly: "Set up my workspace — I'm a swing trader, create a core watchlist with MARA, HOOD, BTC, daily reviews."

That's it. You now have 65 tools, 19 skills, and a personalized workspace. Try /workspace-morning-brief for your first tailored market scan.

What You Can Do

"What are the top gaining stocks today?"
"Show me technicals for AAPL on the hourly timeframe"
"Any insider trades for TSLA in the last 30 days?"
"What's the options chain for AAPL expiring next Friday?"
"What's the current fed funds rate and CPI trend?"
"Convert $10,000 USD to EUR"
"Set up a core watchlist with MARA, HOOD, and BTC"
"Give me a personalized morning brief for my saved watchlist"
