Cursor

Local clients run usmart-mcp over stdio: credentials stay in ~/.usmart on your machine, and the first call opens the browser for uSMART authorization.

Where to find it

Settings → MCP → Add new MCP server (or edit .cursor/mcp.json)

Configuration

{
  "mcpServers": {
    "usmart": {
      "command": "uvx",
      "args": ["--from", "usmart-mcp==1.2.0", "usmart-mcp"],
      "env": { "USMART_READONLY": "1" }
    }
  }
}

Finish authorization

1. Install Python 3.10+ and uv
2. Add usmart-mcp to the client with the configuration above
3. The first call opens the browser for uSMART authorization
4. Stay on USMART_READONLY=1 and verify with check_trade_credentials and list_today_orders
