Installation & Setup

Prerequisite

Make sure you have Node.js installed on your computer.

Step 1: Obtain a StockUp API Key

1. Sign up or log in to the StockUp Developer Console at https://stockup.cc/api.
2. Refill your prepaid wallet and click New Key under API Credentials to generate a secret key (starting with sk_quan_).

Step 2: Configure Claude Desktop

Add this server configuration to your Claude Desktop configuration file:

• MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "stockup": {

      "env": {
        "STOCKUP_API_KEY": "YOUR_SECRET_API_KEY"
