Overview

AI-generated overview

Lets an AI assistant drive a real x64dbg/x32dbg session on Windows: launch or attach, inspect memory and registers, trace execution, dump and repair PE files.

What you can do
Launch and bind a target process or attach to a running one, with arguments, working directory, environment and child-process policy, and wait for breakpoints. Read and change registers, memory, threads, modules and owned breakpoints. Capture runtime evidence: instruction traces, API and heap calls, exceptions and basic-block coverage. Search for comparison values, runtime strings, indirect calls, OEPs and imports. Produce memory PE dumps, minidumps, fixed imports and patched exports, then validate them. Export runtime facts to IDA by file SHA-256 plus module RVA, and sync breakpoints and annotations.
When to use it
Useful for reverse engineering and malware or unpacking analysis on Windows, where the assistant should operate a live debugger and hand reproducible evidence to IDA. Not intended as an IDA replacement.
Requirements
Windows desktop with x64dbg and x32dbg installed; the native plugins copied into their plugin folders; a Python 3.11 virtual environment with the bundled requirements; the stdio launcher configured in the client with the X64DBG_ROOT environment variable and optionally X64DBG_MCP_TOOL_PROFILE. The IDA handoff targets a specific IDA Pro MCP fork.
Before you install
It launches and attaches to processes and can write memory, set breakpoints and export patched binaries, so it changes the state of the debugged target and writes files. ScyllaHide injection is opt-in and its profile compatibility is not guaranteed. Analyze untrusted binaries only inside a disposable VM.

Installation

In SourceWeft

  1. Open x64dbg MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

x64dbg MCP gives an MCP client guarded control of a real x64dbg or x32dbg session. It turns live debugging into a replayable reverse-engineering workflow: bind the exact process, observe runtime facts, recover useful artifacts, validate them independently, and hand the evidence to IDA.

What it does

  • Launches or attaches with arguments, working directory, environment and child-process policy.
  • Reads and changes registers, memory, threads, modules and owned breakpoints.
  • Captures instruction, API, heap, exception and basic-block evidence.
  • Finds comparison values, runtime strings, indirect calls, OEPs and imports.
  • Produces memory PE dumps, minidumps, fixed imports and patched exports.
  • Exchanges runtime facts with IDA using a portable file SHA-256 + module RVA identity instead of unstable runtime addresses.

Quick setup

Download the combined Windows bundle from Releases. It contains both native plugins and the Python backend:

  • plugins\MCPx64dbg.dp64 for x64dbg
  • plugins\MCPx64dbg.dp32 for x32dbg
  • runtime\src and runtime\requirements.txt
  • self-contained x64/x86 managed-runtime probes under runtime\tools\bin\managed_probe

Close x64dbg/x32dbg. Open PowerShell in the folder containing the downloaded ZIP, then run the block below. It asks where to keep the MCP bundle and where x64dbg is already installed; no drive or installation directory is assumed. Keep the same PowerShell window open for the client-specific commands below.

powershell
$Archive = Get-ChildItem -File .\x64dbg-mcp-windows-*.zip |  Sort-Object LastWriteTime -Descending |  Select-Object -First 1if (-not $Archive) { throw 'The x64dbg MCP release ZIP was not found in this folder.' }
$BundleRoot = Read-Host 'Absolute folder where x64dbg MCP should be extracted'$X64dbgRoot = Read-Host 'Absolute folder containing the x64 and x32 x64dbg folders'$BundleRoot = [IO.Path]::GetFullPath(  [Environment]::ExpandEnvironmentVariables($BundleRoot.Trim()))$X64dbgRoot = (Resolve-Path -LiteralPath (  [Environment]::ExpandEnvironmentVariables($X64dbgRoot.Trim()))).Path

Codex

Add the server to ~\.codex\config.toml. Replace the three angle-bracketed values with the absolute paths printed by the setup block. TOML single-quoted strings preserve Windows backslashes as written.

toml
[mcp_servers.x64dbg]command = '<PythonExe>'args = ['<Launcher>']startup_timeout_sec = 90
[mcp_servers.x64dbg.env]X64DBG_ROOT = '<X64dbgRoot>'X64DBG_MCP_TOOL_PROFILE = 'compact'

For normal target startup, call InitDebuggee directly with the EXE path. It detects x86/x64, starts the matching debugger from X64DBG_ROOT, waits for the bridge and opens the target. A separate BridgeHello preflight or manual debugger-path search is not required.

Optional installation check: start x64dbg or x32dbg and verify the bridge:

powershell
& $PythonExe (Join-Path $RuntimeRoot 'src\x64dbg.py') GetDebuggerPluginStatus

GetScyllaHideStatus.installed and integrationReady describe the MCP InjectorCLI/HookLibrary backend. guiPluginPresent describes only the optional x64dbg GUI plugin; it is not required for MCP injection.

ScyllaHide is opt-in: launch tools default to use_scyllahide="off", and auto also skips injection. Use force with an explicit profile when needed. The CLI backend stages a private INI beside the injector and targets the exact PID. Its compatibility configuration disables NtContinueHook and KillAntiAttach together to avoid the reproduced continuation crash; the result reports these overrides. This does not guarantee that every third-party profile is compatible with every target or Windows build.

Claude Code

Add the same stdio server to Claude Code with the user scope. This command uses the paths selected by the setup block instead of embedding a machine-specific location:

powershell
$ClaudeServer = [ordered]@{  command = $PythonExe  args = @($Launcher)  env = [ordered]@{    X64DBG_ROOT = $X64dbgRoot    X64DBG_MCP_TOOL_PROFILE = 'compact'  }} | ConvertTo-Json -Depth 4 -Compressclaude mcp add-json x64dbg $ClaudeServer --scope userclaude mcp list

Alternatively, run claude mcp add and enter the same command, arguments and environment interactively.

Claude Desktop and other stdio clients

Use the client's MCP JSON configuration. For Claude Desktop on Windows, the file is %APPDATA%\Claude\claude_desktop_config.json. Generate a JSON block with the actual paths selected above:

powershell
$ClientConfig = [ordered]@{  mcpServers = [ordered]@{    x64dbg = [ordered]@{      command = $PythonExe      args = @($Launcher)      env = [ordered]@{        X64DBG_ROOT = $X64dbgRoot        X64DBG_MCP_TOOL_PROFILE = 'compact'      }    }  }}$ClientConfig | ConvertTo-Json -Depth 6

Cursor, VS Code MCP, Windsurf and other stdio clients use the same command/args/env contract; only the location of their JSON file differs.

IDA Pro MCP Fusion handoff

The IDA workflow is designed for the rison1337/ida-pro-mcp-fusion fork. x64dbg MCP does not pretend to be an IDA replacement and does not silently mutate an unrelated database. Instead:

  1. ExportRuntimeEvidence writes a versioned evidence document containing the target SHA-256, architecture, module RVAs, executed blocks, API calls, comments, labels and functions.
  2. ResolveModuleRva and the coordinator normalize live addresses to the static image identity.
  3. tools/ida_evidence_coordinator.py validates that the open Fusion database has the same SHA-256 and architecture, then creates deterministic set_name, set_comments, define_func and coverage/API comment actions.
  4. Fusion applies those actions in its IDA worker and can retain the result in its persistent SQLite cache for later multi-binary analysis.

This is an explicit artifact/protocol handoff, so it remains inspectable and retryable. See the coordinator and the Fusion README for the IDA-side worker and cache model.

Documentation

CI covers the Python contract and both native plugin architectures. The release workflow also checks the packaged stdio server and managed probes. Live debugger gates run locally and retain JSON reports; see Contributing. Analyze untrusted binaries inside a disposable VM.

x64dbg MCP даёт MCP-клиенту защищённое управление настоящей сессией x64dbg или x32dbg. Он превращает живую отладку в воспроизводимый reverse-engineering workflow: привязать точный процесс, снять runtime-факты, восстановить полезные артефакты, независимо проверить результат и передать факты в IDA.

Возможности

  • Запуск и attach с аргументами, cwd, окружением и политикой дочерних процессов.
  • Регистры, память, потоки, модули и breakpoint'ы с контролем владельца.
  • Instruction-, API-, heap-, exception-trace и basic-block evidence.
  • Поиск сравнений, runtime-строк, косвенных вызовов, OEP и импортов.
  • PE из памяти, minidump, исправление IAT и экспорт пропатченного файла.
  • Обмен с IDA через переносимую связку SHA-256 файла + module RVA, а не случайный runtime VA.

Быстрая настройка

Скачайте из Releases единый Windows-архив. Внутри сразу есть оба native-плагина и Python-backend:

  • plugins\MCPx64dbg.dp64 для x64dbg
  • plugins\MCPx64dbg.dp32 для x32dbg
  • runtime\src и runtime\requirements.txt
  • автономные x64/x86 managed-runtime probes в runtime\tools\bin\managed_probe

Закройте x64dbg/x32dbg. Откройте PowerShell в папке со скачанным ZIP и выполните блок ниже. Он сам запросит папку для MCP и путь к уже установленному x64dbg — диск и расположение заранее не предполагаются. Не закрывайте это окно PowerShell до выполнения команд для выбранного MCP-клиента.

powershell
$Archive = Get-ChildItem -File .\x64dbg-mcp-windows-*.zip |  Sort-Object LastWriteTime -Descending |  Select-Object -First 1if (-not $Archive) { throw 'Архив релиза x64dbg MCP не найден в этой папке.' }

Codex

Добавьте сервер в ~\.codex\config.toml. Замените три значения в угловых скобках на абсолютные пути, которые напечатал блок настройки. В одинарных строках TOML обратные слеши Windows не нужно удваивать.

toml
[mcp_servers.x64dbg]command = '<PythonExe>'args = ['<Launcher>']startup_timeout_sec = 90
[mcp_servers.x64dbg.env]X64DBG_ROOT = '<X64dbgRoot>'X64DBG_MCP_TOOL_PROFILE = 'compact'

Для обычного запуска цели сразу вызовите InitDebuggee с путём к EXE. Инструмент сам определит x86/x64, запустит подходящий debugger из X64DBG_ROOT, дождётся bridge и откроет цель. Отдельная проверка через BridgeHello и ручной поиск пути к x64dbg не нужны.

Необязательная проверка установки: запустите x64dbg или x32dbg и проверьте bridge:

powershell
& $PythonExe (Join-Path $RuntimeRoot 'src\x64dbg.py') GetDebuggerPluginStatus

Поля GetScyllaHideStatus.installed и integrationReady относятся к backend на базе InjectorCLI, HookLibrary и profile INI. guiPluginPresent сообщает только о необязательном GUI-плагине x64dbg; для MCP-инъекции он не требуется.

ScyllaHide включается явно: launch-инструменты используют use_scyllahide="off" по умолчанию, а auto также пропускает инъекцию. При необходимости используйте force с выбранным профилем. CLI backend создаёт отдельный INI рядом с injector и передаёт точный PID. Для устранения воспроизведённого падения при продолжении он отключает NtContinueHook вместе с KillAntiAttach и сообщает эти изменения в результате. Совместимость остальных настроек профиля зависит от цели и Windows.

Claude Code

Добавьте тот же stdio-сервер в Claude Code с областью пользователя. Команда использует выбранные выше пути, а не расположение с чужого компьютера:

powershell
$ClaudeServer = [ordered]@{  command = $PythonExe  args = @($Launcher)  env = [ordered]@{    X64DBG_ROOT = $X64dbgRoot    X64DBG_MCP_TOOL_PROFILE = 'compact'  }} | ConvertTo-Json -Depth 4 -Compressclaude mcp add-json x64dbg $ClaudeServer --scope userclaude mcp list

Либо запустите claude mcp add и введите те же command, args и env интерактивно.

Claude Desktop и другие stdio-клиенты

Используйте JSON-конфигурацию MCP вашего клиента. В Claude Desktop на Windows это %APPDATA%\Claude\claude_desktop_config.json. Сформируйте JSON с реально выбранными путями:

powershell
$ClientConfig = [ordered]@{  mcpServers = [ordered]@{    x64dbg = [ordered]@{      command = $PythonExe      args = @($Launcher)      env = [ordered]@{        X64DBG_ROOT = $X64dbgRoot        X64DBG_MCP_TOOL_PROFILE = 'compact'      }    }  }}$ClientConfig | ConvertTo-Json -Depth 6

Cursor, VS Code MCP, Windsurf и другие stdio-клиенты используют тот же контракт command/args/env; отличается только путь к JSON-файлу.

Синхронизация с IDA Pro MCP Fusion

Связка рассчитана именно на форк rison1337/ida-pro-mcp-fusion. x64dbg MCP не подменяет IDA и не пишет в случайную базу:

  1. ExportRuntimeEvidence сохраняет версионированный JSON с SHA-256 цели, архитектурой, module RVA, выполненными блоками, API-вызовами, labels, comments и функциями.
  2. ResolveModuleRva и coordinator переводят runtime-адреса в координаты статического образа.
  3. tools/ida_evidence_coordinator.py сверяет SHA-256 и архитектуру открытой Fusion-базы и строит детерминированные действия set_name, set_comments, define_func и комментарии coverage/API.
  4. Fusion применяет действия в своём IDA worker и может сохранить результат в persistent SQLite cache для следующих multi-binary исследований.

Это явный, проверяемый и повторяемый artifact/protocol handoff, а не скрытая связь по нестабильным VA. Подробности: coordinator и README Fusion.

Документация

CI проверяет Python-контракт и native-плагины обеих архитектур. Release workflow также проверяет stdio-сервер и managed probes из собранного архива. Live-проверки debugger выполняются локально и сохраняют JSON-отчёты; см. участие в разработке. Неизвестные бинарники анализируйте в одноразовой VM.
