The x64dbgmcp plugin provides a Model Context Protocol server for x64dbg, enabling you to control the debugger using natural language commands through compatible LLM interfaces. This powerful integration allows direct access to debugging functionality, memory manipulation, and code analysis through conversational AI.
Download the plugin file appropriate for your version:
.dp64
for 64-bit x64dbg.dp32
for 32-bit x86dbgCopy the downloaded file to your x64dbg plugins directory:
[x64dbg_installation_directory]/release/x64/plugins/
To use with Claude Desktop:
x64dbgmcp.py
file from the source directoryclaude_desktop_config.json
with the path to the Python script:{
"mcpServers": {
"x64dbg": {
"command": "Path\\To\\Python",
"args": [
"Path\\to\\x64dbg.py"
]
}
}
}

in x64dbg to view logsThe plugin provides access to over 40 x64dbg functions through natural language. Here are some key function categories:
You can interact with the debugger using natural language commands. Here are some examples:
Setting breakpoints:
Set a breakpoint at the main function and step through the first few instructions
Analyzing memory:
Read 100 bytes from address 0x401000 and show me what's there
Inspecting registers:
What's the current value of RAX and RIP registers?
Finding patterns:
Find the pattern '48 8B 05' in the current module
With x64dbgmcp, you can seamlessly combine the power of language models with x64dbg's debugging capabilities for more intuitive and efficient reverse engineering.
To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "x64dbg" '{"command":"Path\\To\\Python","args":["Path\\to\\x64dbg.py"]}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"x64dbg": {
"command": "Path\\To\\Python",
"args": [
"Path\\to\\x64dbg.py"
]
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json
%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"x64dbg": {
"command": "Path\\To\\Python",
"args": [
"Path\\to\\x64dbg.py"
]
}
}
}
3. Restart Claude Desktop for the changes to take effect
