`bash

STDIO mode (for local MCP clients)

docker run -it --rm --privileged pentest-mcp:latest

HTTP mode (for network access)

docker run -p 8000:8000 -e MCP_TRANSPORT=http --privileged pentest-mcp:latest
`

$3

`bash

Clone and build

git clone https://github.com/dmontgomery40/pentest-mcp.git
cd pentest-mcp
docker-compose build

Run your preferred transport

docker-compose --profile stdio up
docker-compose --profile http up
docker-compose --profile sse up
`

$3

- MCP_TRANSPORT: Choose transport (stdio, http, sse)
- MCP_SERVER_HOST: Bind address (default: 0.0.0.0)
- MCP_SERVER_PORT: Server port (default: 8000)

💬 Usage Examples

$3

`
Set mode to professional.
Scan 192.168.1.0/24 with SYN scan and service detection.
`

$3

`
Scan 10.0.1.0/24 for web servers.
For each web server found, enumerate directories with gobuster using common.txt.
Run nikto against all discovered web servers.
Create a client report summarizing the findings.
`

$3

`
Generate a wordlist for company "Acme Corp" founded in 1995 by John Smith.
Crack these hashes using the generated wordlist:
admin:$1$xyz$...
user:$1$abc$...
`

🔧 System Requirements

🔐 OAuth Authentication (NEW)

$3

Pentest MCP now supports OAuth 2.1 authentication for HTTP/SSE transports, enabling:
- Enterprise SSO Integration: Connect to Auth0, Okta, Azure AD, or any OAuth provider
- Token-Based Security: No more shared secrets or API keys
- Scoped Access Control: Define granular permissions for different users
- Dynamic Client Registration: Automatic client setup with compatible providers

$3

1. Enable OAuth in your .env:
`bash
MCP_OAUTH_ENABLED=true
MCP_OAUTH_PROVIDER_URL=https://your-domain.auth0.com/oauth2
MCP_OAUTH_CLIENT_ID=your_client_id
MCP_OAUTH_CLIENT_SECRET=your_client_secret
MCP_OAUTH_SCOPES=read,write,scan
`

2. Start with HTTP transport:
`bash
MCP_TRANSPORT=http npm start
`

3. Connect with OAuth token:
`javascript
const client = new McpClient();
await client.connect('http://localhost:8000/mcp', {
headers: {
'Authorization': 'Bearer YOUR_ACCESS_TOKEN'
}
});
`

$3

- Auth0: Full support with custom scopes
- Google OAuth: Enterprise workspace integration
- GitHub: Team-based access control
- Azure AD: Microsoft enterprise SSO
- Any OAuth 2.1 Provider: PKCE-compliant providers

$3

When OAuth is enabled, the following endpoints are available:
- /.well-known/oauth-authorization-server - Authorization server metadata
- /.well-known/oauth-protected-resource - Protected resource metadata
- /oauth/authorize - Authorization endpoint (if acting as auth server)
- /oauth/token - Token endpoint (if acting as auth server)

🛡️ Security & Legal

⚠️ AUTHORIZED USE ONLY: This toolkit is for professional penetration testers operating under valid scope of work. Use only on systems and networks for which you have explicit written authorization.

🐳 Docker Security Note: The --privileged flag is required for certain scans (SYN, OS detection). Only use in trusted environments or VMs.

🔍 Troubleshooting

$3


Ensure all required tools are in your PATH:
`bash
which nmap john gobuster nikto
`

$3

For SYN scans and OS detection:
`bash

Run with sudo locally

sudo pentest-mcp

Or use Docker with --privileged

docker run --privileged pentest-mcp:latest
`

$3

`bash
rm -rf node_modules dist
npm install
npm run build
``

$3

- HTTP not accessible: Check firewall rules and port bindings
- SSE connection drops: Ensure keep-alive is enabled
- STDIO hangs: Verify MCP client supports stdio transport
