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.

69 tools across 15 modules — 11 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 49 tools immediately with no API keys. API keys are optional and free — they unlock 20 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:

config.json

Copy

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

This gives you 42 stateless tools with no local data storage.

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

Claude Code shortcut — install as a plugin instead of Steps 1 and 2. If you use Claude Code, skip the manual config above and install everything with two commands:

Code

Copy

/plugin marketplace add yyordanov-tradu/stock-scanner-mcp
/plugin install stock-scanner@tradu-marketplace

Run /reload-plugins, then /mcp — you should see the stock-scanner server listed as connected. The first launch runs npx -y stock-scanner-mcp, which downloads the package once (then it is cached). The plugin enables the workspace by default (data is stored in ~/.stock-scanner-mcp) and passes the optional API keys (FINNHUB_API_KEY, ALPHA_VANTAGE_API_KEY, FRED_API_KEY) through from your environment; modules without a key are skipped automatically.

The plugin already bundles the skills — do NOT run Step 2. All 19 skills ship with the plugin and load under the stock-scanner: namespace, e.g. /stock-scanner:analyze-stock AAPL, /stock-scanner:morning-briefing, /stock-scanner:setup-market-workspace. Running the Step 2 installer as well copies a second, unprefixed set into ~/.claude/skills/, and the two collide — Step 2 is only for the manual (non-plugin) install. After installing, go straight to Step 3, using the namespaced command: /stock-scanner:setup-market-workspace.

Step 2 — Install the trading skills

Skip this step if you installed via the plugin above — the plugin already bundles these skills (as stock-scanner:<name>). This step is only for the manual config in Step 1.

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 69 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"

Highlights

• Stock scanning — screen by price, RSI, volume, market cap with custom filters
• Technical analysis — RSI, MACD, Bollinger Bands, moving averages, pivots across multiple timeframes
• Options flow — chains with Greeks, unusual activity detection, max pain, implied move
• Insider trades — parsed Form 4 transactions with buy/sell/grant details
• Earnings & news — calendar, analyst ratings, company news, short interest
• Crypto — real-time quotes, technicals, trending coins, market stats
• Macro — CPI, GDP, fed funds rate, economic calendar, yield curve data
• Forex — 31 currency pairs from ECB, conversion, historical rates
• Sentiment — CNN Fear & Greed Index, Crypto Fear & Greed
• Market Workspace — save a trading profile, named watchlists, and thesis notes for personalized workflows across sessions

Trading Skills

19 ready-made workflows that chain multiple tools into structured analysis. Each skill orchestrates 5-14 tools in parallel and outputs a verdict with direction, confidence, and key levels.

Skills degrade gracefully when optional API keys are missing. Workspace skills require --enable-workspace in the server config.

npx -p stock-scanner-mcp stock-scanner-install-skills                    # all 19 skills
npx -p stock-scanner-mcp stock-scanner-install-skills --scope project    # project only (.claude/skills/)
npx -p stock-scanner-mcp stock-scanner-install-skills --category macro   # one category
npx -p stock-scanner-mcp stock-scanner-install-skills --category workspace # workspace skills only
npx -p stock-scanner-mcp stock-scanner-install-skills --list             # list without installing
npx -p stock-scanner-mcp stock-scanner-install-skills --force            # overwrite existing

See skills/README.md for the full catalog.

Market Workspace

The Market Workspace is an optional stateful layer that remembers your trading context across sessions — your trading style, named watchlists, and investment thesis notes per symbol. Skills like /workspace-morning-brief use this context to deliver personalized market scans instead of generic ones.

What you can do with it

• /workspace-morning-brief — personalized pre-market scan that reads your profile and watchlist, checks earnings, news, and price action for your names, and highlights what matters today
• Add more watchlists — ask Claude: "Create a watchlist called 'earnings' with AAPL, MSFT, GOOG"
• Track investment theses — save your reasoning per ticker so the system monitors it for you (see below)
• Update anytime — "Add NVDA to my core watchlist" or "Change my review cadence to weekly"

Thesis Tracking

Save your investment reasoning per ticker — direction, key levels, catalysts, and timeframe — so the system can monitor it across sessions.

Save a thesis:

"My thesis on NIO: bullish above $6.35, that confirms the uptrend. Below it the setup is invalid."

Claude saves the structured thesis:
