CarsXE MCP Server: Revolutionizing AI-Powered Vehicle Data Integration

Transform your AI workflows with CarsXE's Model Context Protocol (MCP) server - the ultimate solution for seamless vehicle data integration in 2025.

What is CarsXE's MCP Server?

CarsXE's Model Context Protocol (MCP) server enables AI assistants to directly access comprehensive vehicle data through any MCP-compatible client. This powerful integration allows developers to connect AI tools like Claude, Cursor, and other MCP-compatible applications to CarsXE's extensive automotive database without writing complex API integration code.

Key Features and Capabilities

Comprehensive Vehicle Data Access

The CarsXE MCP server provides access to multiple vehicle data endpoints including:

  • VIN Decoding: Complete vehicle specifications and attributes
  • Market Value Estimation: Current pricing data for sales, loans, and insurance
  • License Plate Decoding: Vehicle specifications in over 50 countries from license plate and registration numbers
  • Vehicle Images: High-quality photos with customizable filters
  • Recall Information: Safety recall data by VIN
  • International VIN Support: Global vehicle database coverage
  • Vehicle History Reports: Detailed past ownership, accidents, and title records
  • License Plate Recognition: Extract vehicle details from plate numbers
  • OBD Code Analysis: Diagnostic trouble code interpretation

AI-First Integration

Unlike traditional API integrations, the CarsXE MCP server is designed specifically for AI workflows, allowing natural language interactions with vehicle data. This means you can ask your AI assistant to "Get the market value for VIN WBAFR7C57CC811956" and receive structured vehicle data instantly.

Step-by-Step Setup Guide

Prerequisites

Before setting up the CarsXE MCP server, ensure you have:

  • A CarsXE API account with valid API key
  • An AI tool that supports MCP (Claude Desktop, Cursor, VS Code with extensions, etc.)
  • Node.js installed (for direct MCP connection)

Setup Method 1: Direct CarsXE MCP Connection (Recommended)

CarsXE provides a direct MCP server endpoint that you can connect to without any third-party integrations.

Step 1: Get Your CarsXE API Key

  1. Create an account at CarsXE API
  2. Complete your billing setup (7-day free trial for many APIs)
  3. Generate your API key from the dashboard

Step 2: Configure Your MCP Client

Add the following configuration to your MCP-compatible application:

For Claude Desktop (claude_desktop_config.json):

claude_desktop_config.jsonjson
{
  "mcpServers": {
    "carsxe": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "https://mcp.carsxe.com/mcp",
        "--header",
        "X-API-Key: YOUR_CARSXE_API_KEY"
      ]
    }
  }
}


For Cursor IDE (settings.json):

settings.jsonjson
{
  "mcpServers": {
    "carsxe": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "https://mcp.carsxe.com/mcp",
        "--header",
        "X-API-Key: YOUR_CARSXE_API_KEY"
      ]
    }
  }
}

Step 3: Test the Connection

  1. Restart your MCP client (Claude Desktop, Cursor, etc.)
  2. Verify the CarsXE server appears in your available tools
  3. Test with a simple query like "Get vehicle specs for VIN WBAFR7C57CC811956"

Setup Method 2: Zapier MCP Integration (Alternative)

Step 1: Generate Your MCP URL

  1. Visit the CarsXE MCP page on Zapier
  2. Click "Generate your secure MCP URL"
  3. Your unique, dynamic MCP server URL will be created instantly

Step 2: Configure Vehicle Data Actions

Customize which specific CarsXE actions your AI assistant can perform:

  • Select relevant vehicle data endpoints
  • Configure API scoping and permissions
  • Align actions with your specific workflows

Step 3: Connect to Your AI Tool

For Claude Desktop:

  1. Open Claude Desktop application
  2. Navigate to Settings > MCP Servers
  3. Add new MCP server with your Zapier-generated URL
  4. Name the server "CarsXE" for easy identification
  5. Save and restart Claude Desktop

For VS Code:

  1. Install an MCP-compatible extension
  2. Add the Zapier MCP server configuration to your settings
  3. Provide the Zapier MCP URL in the server settings

Setup Method 3: Custom MCP Server Development

For developers who prefer direct API control, you can build a custom MCP server using CarsXE's REST API:

Step 1: Install MCP SDK

For Python projects

shell
pip install mcp



For Node.js projects

shell
npm install @modelcontextprotocol/sdk


Step 2: Create MCP Server Configuration

# Python example using FastMCP

carsxe_mcp_server.pypython
from mcp import FastMCP
import requests

mcp = FastMCP("CarsXE Vehicle Data")

@mcp.tool()
def get_vehicle_specs(vin: str) -> dict:
    """Get comprehensive vehicle specifications by VIN"""
    headers = {"Authorization": f"Bearer {CARSXE_API_KEY}"}
    response = requests.get(f"https://api.carsxe.com/specs?vin={vin}", headers=headers)
    return response.json()

@mcp.tool()  
def get_market_value(vin: str) -> dict:
    """Get current market value for a vehicle"""
    headers = {"Authorization": f"Bearer {CARSXE_API_KEY}"}
    response = requests.get(f"https://api.carsxe.com/marketvalue?vin={vin}", headers=headers)
    return response.json()

Step 3: Configure Environment

# Set your CarsXE API key

shell
export CARSXE_API_KEY="your-api-key-here"



# Run the MCP server

shell
python carsxe_mcp_server.py


Advanced Configuration

Environment Variables for Security

For better security practices, you can store your API key as an environment variable:

# Set your CarsXE API key as environment variable

shell
export CARSXE_API_KEY="your-api-key-here"


Then modify your MCP configuration to use the environment variable:

json
{
  "mcpServers": {
    "carsxe": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "https://mcp.carsxe.com/mcp",
        "--header",
        "X-API-Key: ${CARSXE_API_KEY}"
      ]
    }
  }
}


Connection Options

The CarsXE MCP server supports additional configuration options:

json
{
  "mcpServers": {
    "carsxe": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "https://mcp.carsxe.com/mcp",
        "--header",
        "X-API-Key: YOUR_API_KEY",
        "--timeout",
        "30000",
        "--retry",
        "3"
      ]
    }
  }
}
