CS2 RCON MCP

A Model Context Protocol server for CS2 RCON management.

Description

This project provides a Model Context Protocol (MCP) server interface for managing CS2 game servers via RCON. It allows remote control and monitoring of CS2 servers through a standardized protocol.

Features

• Manage your CS2 server in natural language
• RCON command execution
• Manage workshop maps (host, list, change) - Explore Workshop Maps
• SSE-based communication
• Docker support

Available Tools

Tool	Short Description
rcon	Execute any RCON command
status	Get current server status
list_workshop_maps	List all workshop maps on the server
host_workshop_map	Host a workshop map by its ID
workshop_changelevel	Change the map to a given workshop map

Installation

Environment Variables

• HOST: CS2 server IP
• SERVER_PORT: CS2 server port
• RCON_PASSWORD: RCON password

Docker (recommended)

Pull the Docker image from GitHub Container Registry:

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

Docker Environment Variables

When running with Docker, you can set the 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:latest

2. Using a .server-env file: Create a file named .server-env with the following content:

   HOST=your_server_ip
   SERVER_PORT=your_server_port
   RCON_PASSWORD=your_password
   

   Then run the container like this:

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

This provides users with an alternative method to set environment variables, making it easier to manage sensitive information like passwords.

Connecting from Visual Studio Code (GitHub Copilot)

To configure Visual Studio Code to work with the MCP server, follow these steps:

1. Start the MCP Server: Ensure that your MCP server is running before attempting to connect from VS Code.

2. Open Visual Studio Code: Launch VS Code and ensure that you have the GitHub Copilot extension installed and configured.

3. Configure GitHub Copilot:

   • Change the mode from "Ask" to "Agent" mode.

4. Add MCP Server Configuration:

   • Click on the toolbox icon in the upper left corner of the Copilot prompt.
   • Select "Add MCP Server" and choose the option for HTTP - server-sent events.

5. Enter the Server URL:

   • For the URL, input: http://localhost:8080/cs2server/sse. This is the endpoint for the MCP server's SSE connection.

Alternative: Connecting from Cursor (or any other MCP-Client)

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

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

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

Once connected, you can manage your server in natural language.

Example prompts:

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

Happy fragging! 😊
