Reverse Engineering

A sandboxed MCP (Model Context Protocol) tool for reverse engineering that provides a unified interface to various reverse engineering tools with security restrictions.

PyPI Python RuffAsk DeepWiki

Purpose

This project provides a secure, sandboxed environment for executing reverse engineering tools via CLI or MCP protocol. It wraps common reverse engineering utilities (strings, objdump, readelf, binwalk, etc.) with safety features like filesystem isolation, timeouts, and argument validation.

Install

pip install mcp-reverse-engineering

Or for development:

pip install -e ".[dev]"

MCP Server Installation

To use as an MCP server with Claude Desktop:

mcp install src/mcp_reverse_engineering/server.py

Usage

CLI

# Extract strings from a binary
mcp-re --tool strings --file /path/to/binary

# Disassemble a binary
mcp-re --tool objdump --args "['-d']" --file /path/to/binary

# Analyze ELF headers
mcp-re --tool readelf --args "['-h', '-s']" --file /path/to/elf

# Run binwalk for firmware analysis
mcp-re --tool binwalk --file /path/to/firmware.bin

Python API

from mcp_reverse_engineering import ReverseEngineeringEngine

# Create engine with default config
engine = ReverseEngineeringEngine(
    workspace="./workspace",
    timeout=30,
)

# List available tools
print(engine.list_available_tools())

# Execute a tool
result = engine.execute_tool("strings", ["-n", "8"], "/path/to/binary")
print(result)

MCP Server

from mcp_reverse_engineering.server import mcp, strings, objdump, readelf, binwalk

# Run the server (stdio transport for Claude Desktop)
if __name__ == "__main__":
    mcp.run()

API

ReverseEngineeringEngine

Main class for executing reverse engineering tools.

engine = ReverseEngineeringEngine(
    workspace: str = "./workspace",  # Sandbox directory
    timeout: int = 30,               # Tool execution timeout
    config_path: str | Path | None = None,  # YAML config path
)

Methods:

• execute_tool(tool_name: str, args: List[str], file_path: Optional[str] = None) -> str - Execute a tool
• list_available_tools() -> List[str] - List enabled tools
• get_tool_documentation(tool_name: str) -> Dict[str, Any] - Get tool docs
• get_mcp_tools() -> List[Dict[str, Any]] - Get MCP tool schemas

Available Tools
