Binary Ninja MCP

This repository contains a Binary Ninja plugin, MCP server, and bridge that enables seamless integration of Binary Ninja's capabilities with your favorite LLM client.

Features

• Seamless, real-time integration between Binary Ninja and MCP clients
• Enhanced reverse engineering workflow with AI assistance
• Primary support for Claude Desktop as the MCP client, but extensible for other integrations

Examples

Generating a Binary Analysis Report

Renaming Functions

Components

This repository contains two separate components:

1. A Binary Ninja plugin that provides an MCP server that exposes Binary Ninja's capabilities through HTTP endpoints. This can be used with any client that implements the MCP protocol.
2. A separate MCP bridge component that connects your favorite MCP client to the Binary Ninja MCP server. While Claude Desktop is the primary integration path, the MCP server can be used with other clients.

rename_function	Rename a function by its current name to a new user-defined name.
search_functions_by_name	Search for functions whose name contains the given substring.
decompile_function	Decompile a specific function by name and return the decompiled C code.
set_comment	Set a comment at a specific address.

Prerequisites

• Binary Ninja
• Python 3.12+
• Claude Desktop (or your preferred integration)

Installation

Binary Ninja Plugin

You may install the plugin through Binary Ninja's Plugin Manager (Plugins > Manage Plugins).

To manually configure the plugin, this repository can be copied into the Binary Ninja plugins folder.

Claude Desktop Bridge (Optional)

This is only needed if you want to use Claude Desktop as your MCP client. Make sure that you have your virtual environment configured first:

git clone [email protected]:fosdickio/binary_ninja_mcp.git
cd binary_ninja_mcp

python3 -m venv .venv
source .venv/bin/activate   # On macOS/Linux

pip install -r bridge/requirements.txt

Automated Configuration (Mac)

On a Mac, you can automate the setup by running:

./scripts/setup_claude_desktop.py

Manual Configuration

On other operating systems or to manually configure the Claude Desktop integration:

1. Navigate to Settings > Developer > Edit Config
2. Add the following configuration:

{
  "mcpServers": {
    "binary_ninja_mcp": {
      "command": "/ABSOLUTE/PATH/TO/binary_ninja_mcp/.venv/bin/python",
      "args": [
        "/ABSOLUTE/PATH/TO/binary_ninja_mcp/bridge/binja_mcp_bridge.py"
      ]
    }
  }
}

Note: Replace /ABSOLUTE/PATH/TO with the actual absolute path to your project directory. The virtual environment's Python interpreter must be used to access the installed dependencies.

Usage

Claude Desktop

1. Open Binary Ninja and install the Binary Ninja MCP plugin
2. Restart Binary Ninja and then open a binary
3. Start the MCP server (Plugins > MCP Server > Start MCP Server)
4. Launch Claude Desktop

The integration will be automatically available after you open Claude Desktop.

You may now start prompting Claude about the currently open binary. Example prompts:

• "Generate a binary analysis report for the current binary."
• "Rename function X to Y in the current binary."
• "List all functions in the current binary."
• "What is the status of the loaded binary?"

Other MCP Client Integrations

The bridge can be used with other MCP clients by implementing the appropriate integration layer.
