Cheat Engine MCP Bridge

Let multibillion $ AI datacenters analyze the program memory for you.

Connect Cursor, Copilot, Antigravity or your favorite local AI agent via RooCode/Cline directly to Cheat Engine to create mods, trainers, security audits or do anything else with any program/game in a fraction of a time.

The Problem

You're staring at gigabytes of memory. Millions of addresses. Thousands of functions. Finding that one pointer, that one structure takes days or weeks of manual work.

What if you could just ask?

"Find the packet decryptor hook."
"Find the OPcode of character coordinates."
"Find the OPcode of health values."
"Find the unique AOB pattern to make my trainer reliable after game updates."

That's exactly what this does.

- Stop clicking through hex dumps and start having conversations with the memory.

What You Get:

Before (Manual)	After (AI Agent + MCP)
Day 1: Find packet address	Minute 1: "Find RX packet decryption hook"
Day 2: Trace what writes to it	Minute 3: "Generate unique AOB signature to make it update persistent"
Day 3: Find RX hook	Minute 6: "Find movement OPcodes"
Day 4: Document structure	Minute 10: "Create python interpreter of hex to plain text"
Day 5: Game updates, start over	Done.

Your AI can now:

Read any memory instantly (integers, floats, strings, pointers)
Follow pointer chains: [[base+0x10]+0x20]+0x8 → resolved in ms
Auto-analyze structures with field types and values
Identify C++ objects via RTTI: "This is a CPlayer object"
Disassemble and analyze functions
Debug invisibly with hardware breakpoints + Ring -1 hypervisor
And much more!

Installation

pip install -r MCP_Server/requirements.txt

Or manually:

pip install mcp pywin32

[!NOTE] Windows only - Uses Named Pipes (pywin32)

Quick Start

1. Load Bridge in Cheat Engine

1. Enable DBVM in CheatEngine.
2. File → Execute Script → Open ce_mcp_bridge.lua → Execute

Look for: [MCP v11.4.0] Server started on \\.\pipe\CE_MCP_Bridge_v99

2. Configure MCP Client

Add to your MCP configuration (e.g., mcp_config.json):

{
  "servers": {
    "cheatengine": {
      "command": "python",
      "args": ["C:/path/to/MCP_Server/mcp_cheatengine.py"]
    }
  }
}

Restart the IDE to load the MCP server config.

3. Verify Connection

Use the ping tool to verify connectivity:

{"success": true, "version": "11.4.0", "message": "CE MCP Bridge Active"}

4. Start Asking Questions

"What process is attached?"
"Read 16 bytes at the base address"
"Disassemble the entry point"

39 MCP Tools Available

Critical Configuration

BSOD Prevention

[!CAUTION] You MUST disable: Cheat Engine → Settings → Extra → "Query memory region routines"

Enabled: Causes CLOCK_WATCHDOG_TIMEOUT BSODs due to conflicts with DBVM/Anti-Cheat when scanning protected pages.

Example Workflows

Finding a value:

You: "Scan for gold: 15000"  →  AI finds 47 results
You: "Gold changed to 15100"  →  AI filters to 3 addresses
You: "What writes to the first one?"  →  AI sets hardware BP
You: "Disassemble that function"  →  Full AddGold logic revealed

Understanding a structure:

You: "What's at [[game.exe+0x1234]+0x10]?"
AI: "RTTI: CPlayerInventory"
AI: "0x00=vtable, 0x08=itemCount(int), 0x10=itemArray(ptr)..."
