mcp-reverse-engineering 0.1.0.1

A sandboxed MCP tool for reverse engineering with multiple tool integrations

Reverse Engineering Tools MCP Server

mcp-name: io.github.daedalus/mcp_reverse_engineering

A sandboxed MCP (Managed Computation Platform) tool for reverse engineering that provides a unified interface to various reverse engineering tools with security restrictions.

Features

• Sandboxed Execution: All tools run in a restricted environment with timeouts, memory limits, and filesystem jail
• Unified Interface: Single interface to access multiple reverse engineering tools
• Configurable Tool Loading: Select which tools to enable via YAML configuration to avoid overwhelming LLM context windows
• Tool Categories:
  • File Analysis: file, strings, hexdump, xxd
  • Binary Analysis: objdump, readelf, ldd, strace, ltrace, upx, gdb, radare2, angr, ghidra, frida
  • Firmware Analysis: binwalk, unsquashfs, sasquatch, jefferson, ubi_reader, unpackers, retdc, qemu
  • Network Tools: curl, wget
• Advanced Capabilities:
  • Radare2 AST queries
  • Angry symbolic execution
  • Ghidra headless decompilation
  • Automatic unpacker detection
  • Firmware filesystem detection
  • Auto QEMU emulation
• Safety Features:
  • Argument validation
  • Execution sandbox with resource limits
  • File workspace jail
  • Tool output truncation
• Knowledge Base: Built-in documentation for all tools
• Testing: Unit and functional tests included

Installation

pip install -e .

Configuration

Tools are configured via YAML files to control which tools are loaded. This prevents overwhelming LLM context windows by enabling only the tools you need.

Default config (tools_config.yaml): All tools disabled

Example configs:

• examples/minimal.yaml - Only file analysis tools (3 tools)
• examples/firmware.yaml - File + Binary + Firmware analysis
• examples/full.yaml - All 25 tools enabled

# Enable specific tool categories
settings:
  default_timeout: 300

categories:
  file_analysis:
    enabled: true
    tools:
      - file
      - strings
      - hexdump

Usage

# Using the CLI with default config
mcp-re --tool strings --args "-n 10" --file ./binary.exe

# Using a specific config
mcp-re --config examples/minimal.yaml --tool strings --args [] --file ./binary.exe

Programmatic usage:

from mcp_reverse_engineering.core.engine import ReverseEngineeringEngine

# Load with default config (no tools enabled)
engine = ReverseEngineeringEngine()

# Load with specific config
engine = ReverseEngineeringEngine(config_path="examples/minimal.yaml")

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

# Get MCP-compatible tool schemas
print(engine.get_mcp_tools())

# Execute a tool
result = engine.execute_tool("strings", ["-n", "10"], "./binary.exe")
print(result)

Available Tools

Run mcp-re --tool help to see all available tools, or check the knowledge base in the source code.

Security

The tool employs multiple layers of security:

1. Filesystem jail - all operations confined to workspace directory
2. Process resource limits - CPU, memory, process count, file size restrictions
3. Timeout enforcement - prevents hanging operations
4. Argument validation - basic sanitization of inputs
5. Output truncation - prevents excessive data exposure

Testing

Run the test suite:

python -m unittest discover tests

Requirements

See requirements.txt for Python dependencies.

Note: The actual reverse engineering tools (binwalk, radare2, etc.) must be installed separately on the system.
