WooCommerce MCP Server

A Model Context Protocol (MCP) server for integrating WooCommerce with Claude and other AI assistants.

Overview

This server provides tools for AI assistants to interact with a WooCommerce store, allowing them to:

• Fetch recent orders with optional filtering
• Retrieve detailed information about specific orders by ID

The server implements the Model Context Protocol specification, making it compatible with MCP-enabled AI assistants like Claude for Desktop.

Prerequisites

• Node.js v18 or higher
• A WooCommerce store with REST API access
• WooCommerce API credentials (consumer key and secret)

Installation

1. Clone this repository:

git clone https://github.com/techspawn/woocommerce-mcp-server.git
cd woocommerce-mcp-server

2. Install dependencies:

npm install

Configuration

You need to configure your WooCommerce API credentials. You can do this by:

1. Setting environment variables when running the server:

WOOCOMMERCE_URL=https://your-store.com \
WOOCOMMERCE_CONSUMER_KEY=your-consumer-key \
WOOCOMMERCE_CONSUMER_SECRET=your-consumer-secret \
node index.js

2. Or by editing the default values in the index.js file:

const woocommerceConfig = {
  url: process.env.WOOCOMMERCE_URL || 'https://your-store.com',
  consumerKey: process.env.WOOCOMMERCE_CONSUMER_KEY || 'your-consumer-key',
  consumerSecret: process.env.WOOCOMMERCE_CONSUMER_SECRET || 'your-consumer-secret',
  version: 'wc/v3'
};

Running the Server

To run the server directly:

node index.js

Or using the npm script:

npm start

Integration with Claude for Desktop

To connect this server to Claude for Desktop:

1. Make sure you have Claude for Desktop installed

2. Open your Claude Desktop configuration file located at:

   • Windows: %USERPROFILE%\AppData\Roaming\Claude\claude_desktop_config.json
   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json

3. Add your WooCommerce MCP server configuration (create the file if it doesn't exist):

{
  "mcpServers": {
    "woocommerce": {
      "command": "node",
      "args": [
        "/ABSOLUTE/PATH/TO/woocommerce-mcp-server/index.js"
      ],
      "env": {
        "WOOCOMMERCE_URL": "https://your-store.com",
        "WOOCOMMERCE_CONSUMER_KEY": "your-consumer-key",
        "WOOCOMMERCE_CONSUMER_SECRET": "your-consumer-secret"
      }
    }
  }
}

4. Save the file and restart Claude for Desktop

Available Tools

getRecentOrders

Fetches a list of recent orders from your WooCommerce store.

Parameters:

• status (optional): Filter orders by status (e.g., "processing", "completed", "on-hold")
• limit (optional, default: 5): Number of orders to return

getOrderById

Retrieves detailed information about a specific order.

Parameters:

• id: The order ID to retrieve

Building Your Own MCP Server with JavaScript

This section provides a guide to creating your own MCP server using JavaScript/Node.js.

1. Set up a new project

mkdir my-mcp-server
cd my-mcp-server
npm init -y

2. Install dependencies

npm install @modelcontextprotocol/sdk axios zod

3. Create your server file (index.js)

Start with the basic structure:

import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";

// Initialize server
const server = new McpServer({
  name: "My MCP Service",
  version: "1.0.0",
});

// Define and register your tools
server.tool(
  "myToolName",
  {
    // Define parameters using Zod schemas
    param1: z.string().describe("Description of param1"),
    param2: z.number().optional().describe("Optional parameter")
  },
  async ({ param1, param2 }) => {
    // Tool implementation logic here
    const result = `Processed ${param1} with value ${param2 || 'none'}`;
    
    // Return result in the expected format
    return {
      content: [
        {
          type: "text",
          text: result
        }
      ]
    };
  }
);

// Connect the server
const transport = new StdioServerTransport();
await server.connect(transport);

4. Make your package.json ES module compatible

{
  "type": "module",
  "scripts": {
    "start": "node index.js"
  }
}

5. Define tools

MCP tools are defined with three components:

• Name: A unique identifier for the tool
• Parameters: Schema for input parameters (using Zod)
• Handler: Async function that processes the inputs and returns results

Example:

server.tool(
  "calculateTotal",
  {
    items: z.array(
      z.object({
        name: z.string(),
        price: z.number(),
        quantity: z.number().int().positive()
      })
    ).describe("Array of items to calculate total for")
  },
  async ({ items }) => {
    const total = items.reduce((sum, item) => sum + (item.price * item.quantity), 0);
    
    return {
      content: [
        {
          type: "text",
          text: `Total: $${total.toFixed(2)}`
        }
      ]
    };
  }
);

6. Testing locally

You can test your MCP server locally using the stdio transport:

node index.js

7. Debugging tips

• Use console.error() for debugging, not console.log() which interferes with stdio transport
• Check the logs in Claude for Desktop for errors
• Ensure your tool handlers properly handle exceptions
