インストール

クライアントを選択

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "cheatengine-mcp-bridge": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/miscusi-peek/cheatengine-mcp-bridge"
      ]
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "cheatengine-mcp-bridge": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/miscusi-peek/cheatengine-mcp-bridge"
      ]
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "cheatengine-mcp-bridge": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/miscusi-peek/cheatengine-mcp-bridge"
      ]
    }
  }
}

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "cheatengine-mcp-bridge": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/miscusi-peek/cheatengine-mcp-bridge"
      ]
    }
  }
}

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "cheatengine-mcp-bridge",
      "command": "TODO",
      "args": [
        "See README: https://github.com/miscusi-peek/cheatengine-mcp-bridge"
      ]
    }
  ]
}

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json

{
  "context_servers": {
    "cheatengine-mcp-bridge": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/miscusi-peek/cheatengine-mcp-bridge"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

claude mcp add cheatengine-mcp-bridge -- TODO 'See README: https://github.com/miscusi-peek/cheatengine-mcp-bridge'

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方： cheatengine-mcp-bridge

How to solve a CTF memory analysis challenge with Cheat Engine MCP

👤 CTF participants working on binary exploitation or game hacking challenges ⏱ ~30 min intermediate

使うタイミング： You have a CTF challenge that requires finding and manipulating values in a running process.

前提条件

Windows with Cheat Engine installed — Download from cheatengine.org
MCP bridge running — pip install -r MCP_Server/requirements.txt

フロー

Scan for the target value

Attach to the CTF challenge process and scan for an integer value of 100 (my current score).✓ コピーしました

→ List of memory addresses containing the value 100
Narrow down the address

I changed the score to 95. Rescan to find which address actually holds the score.✓ コピーしました

→ Filtered list with likely candidate addresses
Trace the pointer chain

Find the pointer chain to this address so we can reliably locate it after restart.✓ コピーしました

→ Stable pointer path from base module

結果： A reliable pointer chain to the target value for the CTF solution.

注意点

Value stored as float instead of integer — Try scanning as float or double if integer scan returns no results

Reverse engineer game data structures with AI assistance

👤 Game modders and reverse engineers analyzing proprietary software they own ⏱ ~45 min advanced

使うタイミング： You want to understand the memory layout of a program's data structures for educational purposes.

前提条件

Cheat Engine + MCP bridge running — pip install mcp pywin32
Target process you own or have authorization to analyze — Launch the application

フロー

Dissect the structure

Attach to the process and dissect the data structure at address 0x1A3F0000. Identify field types and sizes.✓ コピーしました

→ Structure layout with field offsets, types, and likely names
Find RTTI class info

Check if this address has RTTI information. What C++ class does it belong to?✓ コピーしました

→ Class name and inheritance chain from RTTI

結果： A documented data structure layout with field types and class hierarchy.

注意点

RTTI stripped from release builds — Fall back to manual structure dissection and pattern analysis

組み合わせ

他のMCPと組み合わせて10倍の力を

cheatengine-mcp-bridge + filesystem

Export discovered structures and pointer maps to files for documentation

Document the data structures we found and save them as a markdown file in my notes folder.✓ コピーしました

ツール

このMCPが提供する機能

ツール	入力	呼び出すタイミング
read_memory	address: str, size: int	Read raw bytes from a memory address
read_integer	address: str, size?: int	Read an integer value from memory
scan_all	value: str, type: str	Scan process memory for a specific value
aob_scan	pattern: str	Search for a byte pattern (array of bytes) in memory
disassemble	address: str, count?: int	Disassemble instructions at an address
dissect_structure	address: str, size?: int	Auto-detect structure layout at an address
get_rtti_classname	address: str	Get the C++ class name via RTTI for an object pointer
set_breakpoint	address: str, type?: str	Set a hardware breakpoint for debugging

コストと制限

運用コスト

APIクォータ: N/A — all local
呼び出しあたりのトークン: 200–1000 tokens per tool call
金額: Free — requires Cheat Engine (free) and Windows
ヒント: Use targeted scans (aob_scan, read_integer) instead of full memory dumps to reduce output size.

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： N/A — local tool, no external credentials

データ送信先： All operations are local via Named Pipes. No network calls.

⚠ This tool is designed for authorized security research, CTF competitions, and defensive analysis only. Do not use it against systems you don't own or have written authorization to test.
Windows only — requires Named Pipes support and Cheat Engine installed.
Memory manipulation can crash target processes. Save your work before attaching.

トラブルシューティング

よくあるエラーと対処法

Named Pipe connection failed

Ensure Cheat Engine is running and the Lua bridge script is loaded. Check that both CE and the MCP server run with matching privilege levels (both admin or both user).

確認： Check Cheat Engine's Lua console for pipe creation messages

Access denied reading memory

Run Cheat Engine as Administrator. Some processes require elevated privileges for memory access.

確認： Right-click Cheat Engine → Run as Administrator

Scan returns no results

Try different value types (float vs int, 4-byte vs 8-byte). The value might be stored in an unexpected format.

確認： Try a scan with 'All' value type

代替案

cheatengine-mcp-bridge 他との比較

代替案	代わりに使う場面	トレードオフ
ida-pro-mcp	You need static binary analysis and disassembly rather than live memory manipulation	Static analysis only but much deeper code understanding
mcp-windbg	You need kernel-level debugging or crash dump analysis on Windows	More powerful debugging but steeper learning curve
