@refgrow/mcp

A Model Context Protocol (MCP) server that wraps the Refgrow REST API. This allows AI agents -- Claude Desktop, Cursor, ChatGPT, and other MCP-compatible clients -- to manage your affiliate program directly.

Prerequisites

• Node.js 18+
• A Refgrow account with an API key (generated in project settings)
• API keys start with rgk_

Installation

npm install @refgrow/mcp

Or clone and build from source:

git clone https://github.com/refgrow/refgrow-mcp.git
cd refgrow-mcp
npm install
npm run build

Configuration

The server requires two environment variables:

Variable	Required	Default	Description
REFGROW_API_KEY	Yes	--	Your Refgrow API key (starts with rgk_)
REFGROW_API_URL	No	https://refgrow.com	Base URL of your Refgrow instance

Getting an API Key

1. Log in to Refgrow
2. Go to your project settings
3. Scroll to the API Keys section
4. Click Generate API Key
5. Copy the key (it starts with rgk_ and is shown only once)

Usage with Claude Desktop

Add this to your Claude Desktop config file:

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

{
  "mcpServers": {
    "refgrow": {
      "command": "npx",
      "args": ["-y", "@refgrow/mcp"],
      "env": {
        "REFGROW_API_KEY": "rgk_your_api_key_here"
      }
    }
  }
}

Or if installed globally / from source:

{
  "mcpServers": {
    "refgrow": {
      "command": "node",
      "args": ["/path/to/packages/mcp-server/dist/index.js"],
      "env": {
        "REFGROW_API_KEY": "rgk_your_api_key_here"
      }
    }
  }
}

Usage with Cursor

In Cursor settings, add an MCP server with:

• Name: refgrow
• Command: npx -y @refgrow/mcp
• Environment: REFGROW_API_KEY=rgk_your_api_key_here

Or add to .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "refgrow": {
      "command": "npx",
      "args": ["-y", "@refgrow/mcp"],
      "env": {
        "REFGROW_API_KEY": "rgk_your_api_key_here"
      }
    }
  }
}

Usage with Claude Code

Add to your project's .mcp.json:

{
  "mcpServers": {
    "refgrow": {
      "command": "npx",
      "args": ["-y", "@refgrow/mcp"],
      "env": {
