Install — Claude Desktop

Edit claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "stockmarketscan": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.stockmarketscan.com/mcp"],
      "headers": {
        "X-API-Key": "sms_your_key_here"
      }
    }
  }
}

Restart Claude Desktop. You should see stockmarketscan in the tool picker.

Install — Cursor

Settings → Features → Model Context Protocol → Add New MCP Server:

{
  "name": "stockmarketscan",
  "url": "https://mcp.stockmarketscan.com/mcp",
  "headers": {
    "X-API-Key": "sms_your_key_here"
  }
}

Install — Continue (VS Code / JetBrains)

Edit ~/.continue/config.json:

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "sse",
          "url": "https://mcp.stockmarketscan.com/mcp",
          "headers": {
            "X-API-Key": "sms_your_key_here"
          }
        }
      }
    ]
  }
}

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.

Rate limits

Plan	Per Minute	Per Day	Options Flow
Free	—	—	—
Basic	15	500	—
Pro	30	2,000	✓
