How to Set Up and Use Cobalt Strike
The Cobalt Strike MCP Server provides a bridge between large language models and the Cobalt Strike C2 framework's REST API, enabling AI assistants to interact with adversary simulation workflows through natural language. Developed as a proof-of-concept alongside the Cobalt Strike REST API (introduced in CS 4.12), it lets operators query beacons, review event logs, and drive C2 operations through standardized MCP tools with optional WebSocket stream-backed real-time output. Security professionals running licensed Cobalt Strike team servers can use it to streamline red team operations with AI-assisted command generation and reporting.
Prerequisites
- Python 3.10 or higher installed
- uv installed for dependency management (pip install uv)
- A licensed and running Cobalt Strike installation (version 4.12 or later with the REST API enabled)
- The Cobalt Strike API server running and accessible at its HTTPS endpoint
- An MCP-compatible client such as Claude Desktop
Clone the repository
Clone the Cobalt Strike MCP server repository to your machine.
git clone https://github.com/Cobalt-Strike/cobaltstrike-mcp-server.git
cd cobaltstrike-mcp-serverSet up the environment with uv
Use uv to create and sync the project's virtual environment with all dependencies.
uv syncCreate a .env configuration file
Copy the example environment file and fill in your Cobalt Strike API credentials and server address.
cp .env.example .env
# Edit .env with your values:
# CS_API_BASE_URL=https://your-teamserver:50443
# CS_API_USERNAME=rest_client
# CS_API_PASSWORD=YourPassword
# CS_API_VERIFY_TLS=false
# MCP_TRANSPORT=stdioVerify the installation
Run the server with --help to confirm dependencies are installed and see available options.
uv run python cs_mcp.py --helpStart the MCP server
Launch the server in STDIO mode for direct MCP client integration. Credentials are loaded from the .env file automatically.
uv run python cs_mcp.py --insecureAdd to your MCP client configuration
Register the server with your MCP client so AI assistants can interact with Cobalt Strike.

}Prompts to try
Use these prompts with Claude to interact with a running Cobalt Strike team server.
- "List all active beacons on the team server"
- "Show me the event log from the last hour"
- "What listeners are currently configured on the team server?"
- "Generate a summary report of all current beacon sessions"
- "Show me which beacons have been idle for more than 30 minutes"Troubleshooting Cobalt Strike
Authentication fails with 401 errors against the Cobalt Strike API
Verify CS_API_USERNAME and CS_API_PASSWORD match a user configured in Cobalt Strike with REST API access. Also ensure the REST API server is started from the Cobalt Strike team server with the appropriate port and user roles.
TLS/SSL certificate verification errors when connecting
Set CS_API_VERIFY_TLS=false (or pass --insecure) for self-signed certificates in lab environments. For production, import the team server certificate into your system trust store and set CS_API_VERIFY_TLS=true.
WebSocket stream connection errors at startup
Set CS_WS_ENABLED=false in your .env file to disable WebSocket streams if your team server or network does not support persistent WebSocket connections. The core REST API tools will still function normally.
