Eplan Rag Mcp

THIS IS UNDER DEVELOPMENT !!!!

CLAUDE OR ANY AI STILL DON'T  UNDERSTAND THE CONTEXT ABOUT HOW TO USE THE TOOL, NO UNLESS IT'S GUIDED AND PLANNED. BE CAREFUL

EPLAN AI Automation Toolkit

A collection of AI-assisted automation tools for EPLAN Electric P8 and EPLAN EEC Pro 2026, built around the Model Context Protocol (MCP).

The repo contains three independent sub-projects: a local MCP server that drives EPLAN P8 directly, and two remote MCP servers hosted on Cloudflare Workers that expose the indexed documentation via semantic search.

> Working with an LLM here? Read [llm.md](llm.md) — it explains, in LLM-facing > terms, everything the toolkit can do and configure.

What is MCP?

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

Quick Start

Local EPLAN automation (P8)

The local MCP server lets Claude drive a running EPLAN instance. It exposes 156 tools: 7 connection/utility tools plus 149 EPLAN actions (eplan_*), every one executed silently inside a C# script under QuietMode — no EPLAN dialog can block unattended runs.

The EPLAN version is auto-detected: the server scans C:\Program Files\EPLAN\Platform and targets the newest installed version. No configuration needed.

pip install pythonnet mcp
claude mcp add eplan -- python YOURPATH/eplan-p8-mcp-server/mcp_server/server.py
claude mcp list   # should list "eplan"

Then start EPLAN, open Claude Code, and say connect to eplan. See [eplan-p8-mcp-server/mcp_server/README.md](eplan-p8-mcp-server/mcp_server/README.md) for the full guide.

Precondition of use

To use remoting, please proceed as follows:

To start Eplan remoting, you must first activate the Allow remote access via Remote Client setting. You can do this via GUI in the settings dialog (File > Settings... > Workstation > Interfaces > Remote access).

Remote documentation RAGs (P8 and EEC Pro)

These are already deployed and ready to use — no local data required:

# EPLAN Electric P8 documentation
claude mcp add eplan-rag -- cmd /c npx mcp-remote https://rag2026.covaga.xyz/mcp

# EPLAN EEC Pro 2026 documentation
claude mcp add eecpro-rag -- cmd /c npx mcp-remote https://rageecpro.covaga.xyz/mcp

They also expose a plain REST API (handy for verifying EPLAN action names and parameters while developing):

curl -X POST https://rag2026.covaga.xyz/search -H "Content-Type: application/json" \
     -d "{\"query\": \"export project pdf\", \"topK\": 3}"

See [cloudflare-rag-eplan-p8/README.md](cloudflare-rag-eplan-p8/README.md) and [cloudflare-rag-eecpro/README.md](cloudflare-rag-eecpro/README.md) for the tools, REST endpoints, and architecture.

Claude Code skill for EPLAN development

While the MCP servers let Claude act on EPLAN, the skill teaches Claude to write correct EPLAN code: scripting entry points, verified action parameters, parts-database access, Remote Client automation (dynamic ports, headless EPLAN, Cogineer), and the production pitfalls (pseudo-async command blocking, message-loop monitor thread, dispose discipline, EPLAN 2025 remoting changes).

Install from Claude Code (this repo is also a plugin marketplace):

/plugin marketplace add covagashi/Eplan_2026_IA_MCP_scripts
/plugin install eplan-development@eplan-tools

See [claude-skills/eplan-development/README.md](claude-skills/eplan-development/README.md) for manual installation and details.

Adding New EPLAN Actions

The local MCP server registers tools dynamically from each actions package's __all__ list, so adding an action is just two steps (no per-tool boilerplate).

1. Implement the action

In eplan-p8-mcp-server/mcp_server/api/actions/.py:

def open_project(project_path: str, open_mode: str = None) -> dict:
    """Open a project in EPLAN.

    Args:
        project_path: Full path to the .elk project file.
        open_mode: "Standard", "ReadOnly", or "Exclusive" (optional).
    """
    manager, error = _get_connected_manager()
    if error:
        return error
    action = _build_action("ProjectOpen", Project=project_path, OpenMode=open_mode)
    return manager.execute_action(action)

2. Export it

Add the function to the imports and to __all__ in eplan-p8-mcp-server/mcp_server/api/actions/__init__.py. It is then auto-registered as eplan_open_project.

3. Restart the MCP server

The new tool becomes available after restarting Claude / the server.

4. Validate against the official docs (optional)

eplan-p8-mcp-server/tools/validate_actions.py cross-checks every action name and parameter declared in the wrappers against the official EPLAN docs RAG and writes a markdown report:

python eplan-p8-mcp-server/tools/validate_actions.py

Tips

1. Verify against the docs — use the remote P8 RAG (https://rag2026.covaga.xyz) to confirm the exact EPLAN action name and parameters.
2. Write meaningful docstrings + type hints — they become the tool description and input schema the LLM sees and relies on.
3. Handle paths carefully — Windows paths need escaping (\\) or forward slashes (/).

EPLAN Version Selection (automatic)

There is nothing to configure. On startup the server scans C:\Program Files\EPLAN\Platform for installed versions and:

• Auto mode (default): eplan_connect targets the **newest installed

version** and picks the right .NET runtime automatically (coreclr for EPLAN 2027+, .NET Framework for 2026 and older).

• Explicit mode (LLM's choice): the LLM can call eplan_versions to list

what is installed and then connect to a specific one with eplan_connect(version="2026") — e.g. "connect to eplan 2026".

Notes:

• EPLAN installed somewhere non-standard? Set the EPLAN_PLATFORM_ROOT

environment variable to its Platform folder.

• Once one version's DLLs are loaded into the process, switching to another

version requires restarting the MCP server (a .NET runtime cannot be swapped at runtime).

• eplan_connect also accepts a host (and "host:port") to reach an EPLAN

instance on another machine; port auto-detection only works on localhost.
