Mcpwner

🚀 MCPwner

A Model Context Protocol server for automating security research, integrating security testing tools into LLM - driven workflows.

🚀 Quick Start

MCPwner is a Model Context Protocol (MCP) server that integrates security testing tools into LLM - driven workflows. It offers a unified interface for secret scanning, static analysis (SAST), software composition analysis (SCA), and vulnerability research including 0 - day discovery. Instead of manually chaining tools and pasting outputs into your LLM, MCPwner standardizes and streams results directly into the model's working context, enabling continuous reasoning, correlation, and attack path discovery across the entire security research lifecycle.

⚠️ Important Note

This project is under active development. Learn more about MCPs here.

✨ Features

• 🔧 Unified Interface: A single MCP server integrating multiple security tools (SAST, SCA, secrets detection).
• 🤖 LLM Integration: Structured output formats (SARIF/JSON) for direct consumption by AI assistants.
• 🔍 Continuous Analysis: Correlate findings across multiple tools to identify attack paths and 0 - day vulnerabilities.
• 🏗️ Multi - Agent Architecture: Designed for specialized agents collaborating across security phases.
• 🐳 Containerized Execution: Isolated tool environments for reproducible scans.
• 💾 Automatic Persistence: Workspace and database metadata survives container restarts.
• 🔌 Extensible: Plugin architecture for adding new security tools.

📦 Installation

Prerequisites

System Requirements:

• Docker Engine 20.10+ and Docker Compose 2.0+.
• 8GB RAM minimum (16GB recommended for running multiple tools).
• 20GB free disk space (security tool images are large).
• Supported platforms: Linux, macOS, Windows (with WSL2).

MCP Client:

• Claude Desktop, Cursor, Kiro, or any MCP - compatible client.

Setup

1. Clone the repository:

   git clone https://github.com/yourusername/mcpwner.git
   cd mcpwner
   

2. Configure the server:

   cp config/config.yaml.example config/config.yaml
   # Edit config/config.yaml as needed
   

3. Start the services:

   docker-compose up -d --build
   

4. Verify services are running:

   docker-compose ps
   

Connect Your IDE

Once Docker containers are running, add MCPwner to your MCP client:

Configuration File Locations:

• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS).
• Cursor/Kiro: mcp.json in your project or settings directory.

One - Click Install (requires Docker running):

Manual Configuration: Add the following to your MCP configuration file:

{
  "mcpServers": {
    "mcpwner": {
      "command": "docker",
      "args": ["exec", "-i", "mcpwner-server", "python", "src/server.py"],
      "env": {}
    }
  }
}

Restart your MCP client to load the new server configuration.

Scanning Local Projects

To scan projects from your host machine, mount them into the container by adding a volume in docker-compose.yaml:

services:
  mcpwner:
    volumes:
      - /path/to/your/projects:/mnt/projects:ro

Then use the create_workspace tool with:

• source_type="local"
• source="/mnt/projects/my-project"

💻 Usage Examples

Scan a GitHub Repository for Secrets

"Scan https://github.com/example/repo for secrets"
→ MCPwner runs Gitleaks, TruffleHog, detect - secrets and correlates findings

Security Audit

"Run a security audit on my Python project"
→ MCPwner runs Bandit (SAST), OSV - Scanner (SCA), and secrets scanning

Attack Path Analysis

"Find vulnerabilities in the authentication module"
→ MCPwner runs CodeQL queries, cross - references with secrets and SCA results

Data Persistence

MCPwner automatically persists workspace and CodeQL database metadata across container restarts using file - based storage in the shared Docker volume (/workspaces/.metadata/). No configuration required - the system loads existing data on startup and saves after every operation using atomic writes to prevent corruption.

Workspace Cleanup Control: The cleanup_workspace tool provides granular control:

• delete_files=True, delete_metadata=False - Free disk space but preserve workspace history (recommended).
• delete_files=True, delete_metadata=True - Complete removal of workspace and metadata.
• delete_files=False, delete_metadata=True - Remove from list but keep files on disk.

Backup:

# Backup entire workspaces volume
docker run --rm -v mcpwner_workspaces:/data -v $(pwd):/backup \
  alpine tar czf /backup/workspaces-backup.tar.gz /data

# Restore volume
docker run --rm -v mcpwner_workspaces:/data -v $(pwd):/backup \
  alpine tar xzf /backup/workspaces-backup.tar.gz -C /

Architecture

MCPwner uses HTTP - based communication between containers to support future remote deployments. While currently optimized for local usage, the architecture can be adapted for remote server deployments with minimal modifications.

Design Principles:

• Container isolation for security tool execution.
• Standardized output formats for LLM consumption (SARIF/JSON).
• Extensible plugin architecture for new tools.
• Stateless API (memories are managed by user).

Security Considerations

MCPwner executes security tools that may perform intrusive operations. Only use on systems and codebases you own or have explicit permission to test - unauthorized access is illegal. Restrict MCP server access to authorized users and consider network isolation for production deployments. Review tool configurations before running scans as some tools can generate significant network traffic or system load. Log tool execution and results, keeping in mind that security scans can trigger alerts in monitoring systems. Follow responsible disclosure practices when reporting vulnerabilities discovered using MCPwner. Keep Docker images updated and scan containers for vulnerabilities regularly. Never commit API keys, tokens, or credentials to configuration files - use environment variables or secret management systems instead.
