Example prompts

Drop these straight into Claude Desktop or Cursor once the server is connected:

• "Which stocks appear in both hot-prospects and golden-cross today?"

• "Show me AMD's options flow history for the last 30 days."

• "Find hot-prospects that are forming a cup and handle pattern."

• "Build a full stock report for NVDA — screeners, patterns, options flow, market context."

• "What are today's strongest bullish options flow signals?"

• "Which contracts traded today at vol/OI > 3 with over $1M premium?"

How auth works (BYOK)

The MCP server does not hold its own API key. Each client passes your personal sms_* key, the server validates it once per session, and then proxies tool calls to api/v1/* on your behalf. You stay in control of rate limits and quota, and you can rotate the key any time in Settings.
