EEC Pro 2026

Part of eplan-cloudflare-rags. The local action server lives in eplan-mcp.

Remote MCP server that lets Claude search the EPLAN EEC Pro 2026 documentation through semantic vector search.

Deployed on Cloudflare Workers with Vectorize + Workers AI.

Counterpart of cloudflare-rag-eplan-p8/, which serves the EPLAN P8 docs.

Architecture

Claude Code  -->  MCP (Streamable HTTP)  -->  Cloudflare Worker (eecpro-rag-mcp)
                                                   |
                                              Workers AI (bge-base-en-v1.5)
                                                   |
                                              Vectorize (eecpro-knowledge-base)
                                              ~6,760 vectors / 768 dims / cosine

Source Data

• Local ChromaDB: eplan-eecpro-rag-builder/rag_db_llama_chroma/ in a separate source checkout. Set EEC_PRO_CHROMA_DB_PATH before re-exporting; the index is already deployed to Vectorize.
• Documents: 1,648 markdown pages across 36 categories
• Indexed with: LlamaIndex (MarkdownNodeParser + SentenceSplitter)
• Embedding model: BAAI/bge-base-en-v1.5

Migration Pipeline

# 1. Verify the local ChromaDB and export it to NDJSON batches
python migration/scripts/01_verify_and_export.py

# 2. Deploy to Cloudflare (creates index, uploads vectors, deploys worker)
cd migration && bash scripts/02_deploy_to_cloudflare.sh

Install the MCP in Claude Code

Via mcp-remote

claude mcp add eecpro-rag -- cmd /c npx mcp-remote https://rageecpro.covaga.xyz/mcp

Verify

claude mcp list

eecpro-rag should appear in the list. Then, inside Claude Code:

/mcp

It should show eecpro-rag connected with 2 tools available.

Available Tools

Tool	Description
eecpro_search	Semantic search in EEC Pro documentation. Supports filtering by category (36 categories: refformulas, eececad, eecplc, eecscripting, admin, refcommands, etc.).
eecpro_stats	Statistics for the vector index (number of vectors, dimensions, metric).

EEC Pro Categories

Category	Description
refformulas	Formula language (317 pages)
admin	Installation, configuration, VMArgs (304 pages)
eecbase	Base functionality (119 pages)
refformui	Form-UI reference (84 pages)
refcommands	Commands (79 pages)
refscripting	Scripting reference (58 pages)
concept	Concepts (58 pages)
eececad	ECAD module (47 pages)
eecplc	PLC module (47 pages)
+ 27 more	Tutorials, SAP, Office, Graph2D, etc.

REST Endpoints

In addition to the MCP, the worker exposes a direct REST API. Base URL: https://rageecpro.covaga.xyz.

Method	Endpoint	Description
GET	/health	Health check
POST	/search	Semantic search (body: {"query": "...", "topK": 5})
GET	/stats	Index statistics
POST	/add-vectors	Insert vectors (requires Authorization: Bearer <WORKER_API_KEY>)

Usage Examples

1. Search using cURL (Windows CMD)

curl -X POST https://rageecpro.covaga.xyz/search -H "Content-Type: application/json" -d "{\"query\": \"job server configuration\", \"topK\": 3, \"category\": \"eecjobserver\"}"

2. Search using Python

import requests

url = "https://rageecpro.covaga.xyz/search"
payload = {
    "query": "job server configuration",
    "topK": 3,
    "category": "eecjobserver",  # Optional filter
}
headers = {"Content-Type": "application/json"}

response = requests.post(url, json=payload, headers=headers)
print(response.json())
