# CtrEditor MCP Server Documentation

## 🎯 Overview

The CtrEditor MCP (Model Context Protocol) Server transforms the CtrEditor WPF application into a programmable automation platform for debugging, testing, and simulation control. This server enables remote control of all major application features through JSON-RPC style communication.

## 🚀 Architecture

### Communication Flow
```
LLM/Client ↔ MCP Proxy (Python) ↔ CtrEditor MCP Server (C#) ↔ WPF Application
```

### Connection Setup
- **Protocol**: TCP Socket on port 5006
- **Format**: JSON-RPC style messages
- **Proxy**: Python proxy for VS Code Copilot integration

### VS Code Configuration
```json
"ctreditor": {
    "command": "C:/Users/migue/miniconda3/envs/mcp_proxy/python.exe",
    "args": [
        "d:/Proyectos/Scripts/MCP_Proxy/mcp_proxy.py",
        "--host", "localhost",
        "--port", "5006",
        "--name", "CtrEditor",
        "--description", "CtrEditor WPF Application MCP Server for debugging and testing"
    ]
}
```
