CS2 RCON MCP server

This MCP server provides a natural language interface for managing CS2 game servers via RCON. It allows you to control and monitor your CS2 servers through a standardized protocol, making administration more intuitive.

Installation

You can install the CS2 RCON MCP server using pip:

pip install -e .

Running the Server

After installation, start the server with:

python -m rcon_mcp

Environment Variables

Configure your server connection with these environment variables:

• HOST: CS2 server IP address
• SERVER_PORT: CS2 server port number
• RCON_PASSWORD: RCON password for authentication

Docker Installation (Recommended)

Pulling the Docker Image

docker pull ghcr.io/v9rt3x/cs2-rcon-mcp:main

Running with Docker

You can set environment variables in two ways:

1. Directly in the command:

   docker run -p 8080:8080 \
     -e HOST=your_server_ip \
     -e SERVER_PORT=your_server_port \
     -e RCON_PASSWORD=your_password \
     ghcr.io/v9rt3x/cs2-rcon-mcp:main
   

2. Using a .server-env file: Create a file named .server-env with your settings:

   HOST=your_server_ip
   SERVER_PORT=your_server_port
   RCON_PASSWORD=your_password
   

   Then run the container:

   docker run -p 8080:8080 --env-file .server-env ghcr.io/v9rt3x/cs2-rcon-mcp:main
   

Available Commands

• rcon <command>: Execute any RCON command
• status: Get current server status
• changelevel <map_name>: Change the current map
• mp_warmup_end: End the warmup phase
• mp_restartgame 1: Restart the game
• And many other CS2 server commands

Connecting from Visual Studio Code (GitHub Copilot)

1. Start the MCP Server before connecting from VS Code
2. Launch VS Code with GitHub Copilot extension installed
3. Configure GitHub Copilot:
   • Change mode from "Ask" to "Agent" mode
4. Add MCP Server Configuration:
   • Click the toolbox icon in the upper left of the Copilot prompt
   • Select "Add MCP Server" and choose HTTP - server-sent events
5. Enter Server URL: http://localhost:8080/cs2server/sse

Connecting from Cursor or Other MCP Clients

1. Start the MCP server
2. Configure Cursor's MCP settings by creating/updating ~/.cursor/mcp.json:

   {
     "mcpServers": {
       "cs2server": {
         "url": "http://localhost:8080/cs2server/sse"
       }
     }
   }
   

3. Open the MCP panel in Cursor (usually in the sidebar)
4. The server should automatically connect using the configured URL

Example Usage

Once connected, you can manage your server using natural language prompts like:

• "Add 5 bots to the server and start a competitive match on de_dust2"
• "What's the current server status? How many players are connected and what map are we on?"

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
