EPLAN Automation Tools

This repository contains tools for automating EPLAN Electric P8 using AI assistants. Currently is 100% functional

MCP Server (Recommended)

The MCP Server (mcp_server/) allows any AI to control EPLAN directly through the Model Context Protocol.

What is MCP?

MCP (Model Context Protocol) is an open standard that allows AI assistants like Claude to interact with external tools and services. Instead of just generating code, Claude can actually execute actions in EPLAN in real-time.

With MCP, you can:

• Connect to a running EPLAN instance
• Execute EPLAN actions directly from Claude
• Get real-time feedback on operations
• Automate complex workflows through natural conversation

Prerequisites

• Python 3.10+ installed and added to PATH
• EPLAN Electric P8 installed (2024 or later recommended)
• Claude Code CLI installed (Installation guide)

Installation Steps

Step 1: Install Python Dependencies

Open a terminal and run:

pip install pythonnet mcp

Step 2: Configure Claude Code CLI

Add the MCP server to Claude Code. Replace YOURPATH with the actual path to the scripts folder:

claude mcp add eplan -- python YOURPATH\Eplan_2026_IA_MCP_scripts\mcp_server\server.py

Example with full path:

claude mcp add eplan -- python D:\1_GENERAL\Eplan_2026_IA_MCP_scripts\mcp_server\server.py

Step 3: Verify Configuration

Check that the MCP server was added correctly:

claude mcp list

You should see eplan in the list of configured MCP servers.

Step 4: Start EPLAN

1. Open EPLAN Electric P8
2. Make sure it's fully loaded before connecting

Step 5: Start Claude Code and Connect

1. Open a terminal and run claude
2. Ask Claude to connect to EPLAN:

   connect to eplan
   

3. Claude will auto-detect the running EPLAN instance and connect

Troubleshooting

Issue	Solution
"pythonnet not found"	Run pip install pythonnet
"Cannot connect to EPLAN"	Make sure EPLAN is running and fully loaded
"MCP server not found"	Check the path in claude mcp list and verify the file exists
"Port not found"	EPLAN API server may not be running; restart EPLAN

Uninstalling

To remove the MCP server from Claude Code:

claude mcp remove eplan

Adding New EPLAN Actions

The MCP server is designed to be easily extensible. Here's how to add new EPLAN actions:

Step 1: Add the Function to eplan_actions.py

def example_project(project_path: str) -> dict:
    """
    Open an EPLAN project.
    Action: example
    """
    manager = get_manager(TARGET_VERSION)

    if not manager.connected:
        return {"success": False, "message": "Not connected to EPLAN"}

    # Note: Use forward slashes or escape backslashes in the path
    return manager.execute_action(f'example /param1:"{project_path}"')

Step 3: Register the Tool in server.py

from eplan_actions import close_project, example_project  # Add your import

@mcp.tool()
def example_project(project_path: str) -> str:
    """Open an EPLAN project by path."""
    return json.dumps(example_project(project_path), indent=2)

Step 4: Restart Claude CLI

The new tool will be available after restarting Claude CLI.

Tips for Adding Actions

1. Test in EPLAN first - Use EPLAN's scripting to verify the action works
2. Check parameters - Each action has specific parameters; refer to the API documentation
3. Handle paths carefully - Windows paths need escaping or use forward slashes
4. Add meaningful docstrings - Claude uses the docstring to understand when to use the tool

Changing EPLAN Version

The target EPLAN version is configured in 3 files. Update all of them when switching versions (e.g. from "2025" to "2026"):

File	What to change
mcp_server/server.py	TARGET_VERSION = "2025"
mcp_server/actions/_base.py	TARGET_VERSION = "2025"
mcp_server/eplan_connection.py	Default parameter in __init__ and get_manager (target_version: str = "2025")
