Store (E-Commerce) MCP server

The MCP Store server provides a Model Context Protocol implementation for retrieving and working with customer and order information from a store API. It enables Claude to search for customers and access their order history through a simple interface.

Prerequisites

• Node.js (latest LTS version recommended)
• A local API server running on http://localhost:3000 that provides customer and order data

Installation

# Clone the repository
git clone <repository-url>
cd mcp-store

# Install dependencies
npm install

# Build the project
npm run build

Usage

The MCP server offers several tools for accessing store data:

get-all-customers

Returns a list of all customers in the store database. This tool requires no parameters and will retrieve the complete customer list.

get-customer-by-name

Searches for customers by name and returns all matching results.

Parameters:

• customerName: The name to search for

Example usage:

Tool: get-customer-by-name
Parameters: {"customerName": "John Smith"}

get-all-orders-by-customer

Retrieves all orders placed by a specific customer.

Parameters:

• customerId: The unique identifier for the customer

Example usage:

Tool: get-all-orders-by-customer
Parameters: {"customerId": "123456"}

Data Models

The MCP server works with the following data structures:

Customer Data

interface ICustomer {
  name: string;
  email: string;
  phone?: string;
  address?: {
    street?: string;
    city?: string;
    state?: string;
    zip?: string;
    country?: string;
  };
  createdAt?: Date;
}

Order Data

interface IOrder {
  customer: string;
  items: IOrderItem[];
  totalAmount: number;
  status?: "pending" | "processing" | "shipped" | "delivered" | "cancelled";
  paymentMethod?: "credit_card" | "debit_card" | "paypal" | "cash";
  createdAt?: Date;
}

interface IOrderItem {
  product: string;
  quantity: number;
  price: number;
}

Product Data

interface IProduct {
  name: string;
  description?: string;
  price: number;
  category?: string;
  inStock?: boolean;
  createdAt?: Date;
}

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mcp-store" '{"command":"npx","args":["-y","mcp-store"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mcp-store": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-store"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "mcp-store": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-store"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
