Cobalt Strike MCP Server - provides access to Cobalt Strike API operations

Cobalt Strike MCP Server

An MCP (Model Context Protocol) server that provides access to Cobalt Strike API operations.

Features

• Automatic Authentication: Authenticates with Cobalt Strike API and manages bearer token
• Dynamic Tool Generation: Automatically creates MCP tools from the OpenAPI specification
• Full API Coverage: Exposes all Cobalt Strike API operations as MCP tools

Setup

1. Install dependencies:

pip install -r requirements.txt

2. Configure environment variables (copy .env.example to .env and edit):

cp .env.example .env

3. Set your Cobalt Strike credentials:

export CS_BASE_URL="https://your-cs-server:50443"
export CS_USERNAME="your-username"
export CS_PASSWORD="your-password"
export CS_VERIFY_SSL="false"  # Set to "true" if using valid SSL cert

Usage

Running the Server

python server.py

Using with MCP Client

Add to your MCP client configuration (e.g., Claude Desktop):

{
  "mcpServers": {
    "cobalt-strike": {
      "command": "python",
      "args": ["/path/to/CS-MCP/server.py"],
      "env": {
        "CS_BASE_URL": "https://your-cs-server:50443",
        "CS_USERNAME": "your-username",
        "CS_PASSWORD": "your-password",
        "CS_VERIFY_SSL": "false"
      }
    }
  }
}

How It Works

1. Authentication: On startup, the server authenticates with /api/auth/login and retrieves a bearer token
2. API Client Initialization: Creates an HTTP client with the bearer token in the Authorization header
3. OpenAPI Spec Loading: Fetches the OpenAPI specification from /v3/api-docs
4. Tool Generation: Dynamically creates MCP tools for each API operation
5. Request Handling: Routes tool calls to the appropriate API endpoints with proper authentication

Environment Variables

• CS_BASE_URL: Base URL of the Cobalt Strike server
• CS_USERNAME: Username for authentication (required)
• CS_PASSWORD: Password for authentication (required)
• CS_VERIFY_SSL: Whether to verify SSL certificates (default: false)

Security Notes

• Store credentials securely (use environment variables, not hardcoded values)
• Consider using SSL certificate verification in production (CS_VERIFY_SSL=true)
• The bearer token is managed automatically and refreshed as needed
