🤖 What is this?

TastyScanner MCP Server connects Claude, GPT, or any AI agent to your TastyTrade account via the Model Context Protocol.

Ask your AI assistant to:

• "Scan the market for high IVR stocks"
• "Build an Iron Condor on SPY with 30-45 DTE"
• "Show my positions and P&L"
• "Close my AAPL position at 50% profit"

cp .env.example .env
# Edit .env with your TastyTrade OAuth credentials

2. Build and run

docker compose build
docker compose up -d
curl http://localhost:7698/health

3. Connect to Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "tastytrade": {
      "url": "http://localhost:7698/mcp"
    }
  }
}

Development

Run locally (without Docker)

cd tastyscanner-mcp
npm install

# Copy env template and fill in credentials
cp .env.example .env
# Edit .env with your OAuth credentials

# Run with hot-reload
npm run dev

# Or build and run
npm run build
npm start

Test with curl

# Initialize MCP session (add -H "Authorization: Bearer <token>" if MCP_AUTH_TOKEN is set)
curl -X POST http://localhost:7698/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-auth-token" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "initialize",
    "params": {
      "protocolVersion": "2025-03-26",
      "capabilities": {},
      "clientInfo": {"name": "test", "version": "1.0.0"}
    }
  }'

# Call a tool (use session-id from init response)
curl -X POST http://localhost:7698/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-auth-token" \
  -H "mcp-session-id: <session-id>" \
  -d '{
    "jsonrpc": "2.0",
    "id": 2,
    "method": "tools/call",
    "params": {
      "name": "get_connection_status",
      "arguments": {}
    }
  }'

Environment Variables

Variable	Required	Default	Description
TASTY_CLIENT_ID	Yes	—	TastyTrade OAuth Client ID
TASTY_CLIENT_SECRET	Yes	—	TastyTrade OAuth Client Secret
TASTY_REFRESH_TOKEN	Yes	—	TastyTrade OAuth Refresh Token
TASTY_ACCOUNT	No	auto	Account number (auto-detects first)
TASTY_PRODUCTION	No	true	true = production, false = sandbox
MCP_PORT	No	7698	HTTP server port
MCP_AUTH_TOKEN	No	—	Bearer token for endpoint auth. If set, all /mcp requests require Authorization: Bearer <token>
LOG_LEVEL	No	info	debug, info, warn, error
ENABLE_LIVE_TRADING	No	false	Set true to allow execute_trade and adjust_order

Security Notes

• Authentication: Set MCP_AUTH_TOKEN in .env to require Bearer token auth on all /mcp endpoints. Without it, the server is open (backwards compatible but not recommended for production).
• Rate limiting: 120 requests/minute per IP on MCP endpoints.
• CORS: Restricted to MCP_CORS_ORIGIN (default http://localhost:3333).
• Credentials are passed via environment variables, never hardcoded.
• execute_trade and adjust_order require ENABLE_LIVE_TRADING=true — disabled by default.
• Session IDs use crypto.randomUUID() (cryptographically secure).
• Account numbers are masked in logs (last 4 digits only).
• Do not expose port 7698 to the internet without auth enabled.
