Connect RewardSmart
to Windsurf

Prerequisites

1 Setup Instructions

1. 1

   Get your RewardSmart API token

   Open the RewardSmart app. Go to Settings → Integrations → MCP Access and tap Generate Token. Copy the token.

2. 2

   Open the Windsurf MCP config file

   Windsurf stores its MCP configuration at a global location. Open the file in a text editor — create it if it doesn't exist:

   Path (macOS / Linux) Copy

   ~/.codeium/windsurf/mcp_config.json

   Path (Windows) Copy

   %USERPROFILE%\.codeium\windsurf\mcp_config.json

   You can also open it from Windsurf via Windsurf Settings → Cascade → MCP Servers → Edit Config.

3. 3

   Add the RewardSmart MCP server

   Add the following configuration. Replace YOUR_TOKEN_HERE with your API token.

   mcp_config.json Copy

   {
     "mcpServers": {
       "rewardsmart": {
         "command": "npx",
         "args": ["-y", "@rewardsmart/mcp-server"],
         "env": {
           "REWARDSMART_API_KEY": "YOUR_TOKEN_HERE"
         }
       }
     }
   }

   ⚠️ If the file already exists with other MCP servers, merge the "rewardsmart" block into the existing "mcpServers" object — don't create a duplicate key.
4. 4

   Reload Windsurf

   Save the config file and reload Windsurf. You can use Windsurf Settings → Cascade → MCP Servers → Refresh, or fully restart the editor.

5. 5

   Test with Cascade

   Open the Cascade AI chat panel. Look for the RewardSmart tool in the available tools list. Ask: "Which of my cards gives the best rewards at grocery stores?"

   ✅ Cascade will call the RewardSmart MCP tool and return your personalized card recommendations.
