🤖 MCP Server Integration with LLMs

The BugBounty MCP Server implements the Model Context Protocol (MCP), enabling seamless integration with various LLM applications for natural language penetration testing.

🔗 Supported LLM Clients

1. Claude Desktop (Recommended)

Add to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

For Docker (recommended):

{
  "mcpServers": {
    "bugbounty-mcp": {
      "command": "docker",
      "args": ["exec", "-i", "bugbounty-mcp-server", "bugbounty-mcp", "serve"],
      "env": {
        "DOCKER_HOST": "unix:///var/run/docker.sock"
      }
    }
  }
}

For Native Installation:

{
  "mcpServers": {
    "bugbounty-mcp": {
      "command": "/Users/your-username/Documents/bugbounty-mcp-server/run.sh",
      "args": ["serve"],
      "env": {
        "PATH": "/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin"
      }
    }
  }
}

2. VS Code with GitHub Copilot Integration

To use the BugBounty MCP Server with VS Code and GitHub Copilot:

Prerequisites:

VS Code with GitHub Copilot extension enabled
MCP extension for VS Code (if available in marketplace)

Configuration Steps:

For Docker Deployment (Recommended):

First, ensure your Docker container is running with port 3001 exposed:

# Start the container with automatic MCP server startup
docker-compose up --build -d

# Verify the server is accessible on port 3001
nc -z localhost 3001 && echo "MCP server is ready"

Then configure VS Code MCP settings by opening VS Code settings (Cmd/Ctrl + ,) and adding:

{
  "mcp.servers": {
    "bugbounty-docker": {
      "command": "nc",
      "args": ["localhost", "3001"],
      "description": "BugBounty MCP Server running in Docker",
      "env": {
        "LOG_LEVEL": "info"
      }
    }
  }
}

Alternative Docker configuration using direct Docker exec:

{
  "mcp.servers": {
    "bugbounty-docker": {
      "command": "docker",
      "args": ["exec", "-i", "bugbounty-mcp-server", "bugbounty-mcp", "serve"],
      "description": "BugBounty MCP Server via Docker exec",
      "env": {
        "DOCKER_HOST": "unix:///var/run/docker.sock"
      }
    }
  }
}

For Native Installation:

{
  "mcp.servers": {
    "bugbounty-native": {
      "command": "/Users/your-username/Documents/bugbounty-mcp-server/run.sh",
      "args": ["serve"],
      "description": "BugBounty MCP Server native installation",
      "env": {
        "PATH": "/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin"
      }
    }
  }
}

Verify Connection:
- Restart VS Code or reload the MCP extension
- Open the MCP panel in VS Code (if available)
- You should see the BugBounty server connected
- Test by asking GitHub Copilot: "List available security tools from BugBounty MCP"

Troubleshooting Docker Integration:

If using the Docker network approach and experiencing issues:

# Check if container is running and healthy
docker-compose ps

# Test network connectivity
nc -z localhost 3001 || echo "Port 3001 not accessible"

# Check container logs
docker-compose logs -f bugbounty-mcp

# Verify MCP server response
echo '{"jsonrpc": "2.0", "method": "initialize", "params": {"protocolVersion": "2024-11-05", "capabilities": {}, "clientInfo": {"name": "test", "version": "1.0"}}, "id": 1}' | nc localhost 3001

3. Custom MCP Clients

import asyncio
from mcp.client.session import ClientSession
from mcp.client.stdio import stdio_client

async def use_bugbounty_mcp():
    async with stdio_client(["./run.sh", "serve"]) as (read, write):
        async with ClientSession(read, write) as session:
            # Initialize the session
            await session.initialize()
            
            # List available tools
            tools = await session.list_tools()
            print(f"Available tools: {len(tools)}")
            
            # Call a tool
            result = await session.call_tool(
                "subdomain_enumeration",
                {"domain": "example.com", "passive_only": True}
            )
            print(result)

# Run the client
asyncio.run(use_bugbounty_mcp())

4. Integration Examples

Start the server and test:

# Terminal 1: Start the MCP server
./run.sh serve

# Terminal 2: Test with any MCP client
# The server will be listening on stdio for MCP protocol messages

Example LLM conversation:

User: "Please perform a comprehensive security assessment of example.com"

LLM: I'll help you conduct a comprehensive security assessment using the BugBounty MCP tools. Let me start by gathering information about the target.

[The LLM will automatically use tools like:]
- subdomain_enumeration to find subdomains
- port_scanning to identify open services  
- vulnerability_scanning to detect security issues
- web_directory_scanning to find hidden files
- And 90+ other security tools as needed

🔧 Troubleshooting MCP Integration

If the server doesn't start in Claude Desktop:

For Docker deployment:

Ensure Docker container is running:

docker ps | grep bugbounty-mcp
# Should show running container

Check container logs:
```
docker logs bugbounty-mcp-server
```

Test Docker integration:

docker exec bugbounty-mcp-server bugbounty-mcp --help
# Should show help output

Verify Docker socket access (macOS/Linux):

ls -la /var/run/docker.sock
# Should be accessible

For Native deployment:

Check the path in your config:

# Get the absolute path
pwd
# Use this full path in claude_desktop_config.json

Verify the run.sh script is executable:
```
chmod +x run.sh
```

Test the server manually:

./run.sh serve
# Should show "BugBounty MCP Server started successfully"

Check Claude Desktop logs:
- macOS: ~/Library/Logs/Claude/
- Windows: %LOCALAPPDATA%\Claude\logs\
