How to Access Live Epicor Kinetic Data in Visual Studio Code via Cline

Cline is an autonomous coding agent right in your IDE, capable of creating/editing files, running commands, using the browser, and more with your permission every step of the way. When paired with the CData MCP Server for Epicor Kinetic, you get live access to CRM data within your IDE, enabling you to build, test, and validate data-driven features using real-time schema and records without ever leaving your development environment.

This article outlines how to run the CData MCP Server for Epicor Kinetic on WSL (Windows Subsystem for Linux) and connect to it from the Cline extension in Visual Studio Code on Windows.

Background

CData MCP Servers are typically designed for clients like Claude Desktop. However, when attempting to use the server via the Cline extension in Windows VS Code, the following error occurred:

MCP error -32000: Connection closed

This issue is suspected to be caused by I/O handling problems in the stdio transport implementation on the Windows version of the Cline extension.

• Related GitHub Issue: https://github.com/cline/cline/issues/3464
• Additionally, environment variables such as PATH may not be inherited correctly when launching processes like Java or Node.

Prerequisites

• Visual Studio Code installed on Windows
• Cline extension installed and configured in VS Code
• Windows Subsystem for Linux (WSL) installed with a working Linux distribution (e.g., Ubuntu)
• Java 21+ JRE installed in WSL
• CData MCP Server for Epicor Kinetic installed on Windows

Step 1: Authenticate with Epicor Kinetic (on Windows)

Before running the MCP Server in WSL, you must complete authentication flow in a Windows environment. This ensures all necessary credentials are generated and stored properly. Find and run the "CData MCP Server for Epicor Kinetic" or execute the MCP Server JAR file to open the configuration wizard.

java -jar "C:\Program Files\CData\CData MCP Server for Epicor Kinetic 2024\lib\cdata.mcp.epicorerp.jar"

Connecting to Epicor Kinetic

To successfully connect to your ERP instance, you must specify the following connection properties:

• Url:the URL of the server hosting your ERP instance. For example, https://myserver.EpicorSaaS.com
• ERPInstance: the name of your ERP instance.
• User: the username of your account.
• Password: the password of your account.
• Service: the service you want to retrieve data from. For example, BaqSvc.

In addition, you may also set the optional connection properties:

• ApiKey: An optional key that may be required for connection to some services depending on your account configuration.
• ApiVersion: Defaults to v1. May be set to v2 to use the newer Epicor API.
• Company: Required if you set the ApiVersion to v2.

Configuring the CData MCP Server

Name your MCP Server (e.g. cdataepicorerp), enter the required connection properties, and click "Connect."

Upon successful connection, the following directory and files will be created:

C:\Users\<username>\AppData\Roaming\CData\epicorerp Provider\
 |-- cdataepicorerp.mcp
 |-- (other supporting config files)

Step 2: Copy the MCP Server Configuration into WSL

Next, copy the entire configuration folder from Windows into your WSL environment.

mkdir -p ~/.config/CData/
cp -r /mnt/c/Users/<username>/AppData/Roaming/CData/"epicorerp Provider" ~/.config/CData/

Ensure the destination path matches exactly: ~/.config/CData/epicorerp Provider/.

Step 3: Install the MCP Server on WSL

Install Java and place the MCP Server JAR in the desired location within WSL:

sudo apt update
sudo apt install openjdk-21-jre-headless
sudo mkdir -p /opt/cdata/mcp_epicorerp/lib
sudo cp /mnt/c/Program\ Files/CData/CData\ MCP\ Server\ for\ Epicor Kinetic\ 2024/lib/cdata.mcp.epicorerp.jar /opt/cdata/mcp_epicorerp/lib/

Step 4: Configure Cline

Now, configure the Cline extension to launch the MCP Server inside WSL using the wsl command.

Create or update cline_mcp_settings.json with the following content:

{
  "mcpServers": {
    "cdataepicorerp": {
      "autoApprove": ["*"],
      "disabled": false,
      "timeout": 60,
      "type": "stdio",
      "command": "wsl",
      "args": [
        "-d",
        "Ubuntu", // Replace with your installed WSL distro name
        "--",
        "/usr/bin/java",
        "-jar",
        "/opt/cdata/mcp_epicorerp/lib/cdata.mcp.epicorerp.jar",
        "cdataepicorerp"
      ],
      "env": {
        "JAVA_TOOL_OPTIONS": "-Xmx2g"
      }
    }
  }
}

Note: Replace Ubuntu with your actual WSL distribution name (e.g., Ubuntu-22.04). Run wsl -l in PowerShell or CMD to confirm.

Step 5: Interact with Live Data in Cline

From within Visual Studio Code, you can now run MCP commands through the Cline extension.

cdataepicorerp_get_tables
cdataepicorerp_get_columns Customers

If configured correctly, these commands will return a list of available Epicor Kinetic objects and metadata, allowing you to interact with your CRM schema in real time.

Try natural language prompts like:

• "Generate a React form to create a new Epicor Kinetic Lead."
• "Write a Python function to pull Opportunities closed this quarter."
