CS2 RCON MCP server

This MCP server provides a natural language interface for managing Counter-Strike 2 (CS2) game servers via RCON. You can execute commands, manage workshop maps, and monitor your CS2 server using standardized protocols.

Features

• Natural language management of CS2 servers
• RCON command execution
• Workshop map management (hosting, listing, changing)
• SSE-based communication
• Docker support

Available Tools

• 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

Using Docker (Recommended)

Pull the Docker image:

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

Required Environment Variables

You'll need to configure these environment variables:

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

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:latest

2. Using a .server-env file:

Create a file named .server-env with your configuration:

HOST=your_server_ip
SERVER_PORT=your_server_port
RCON_PASSWORD=your_password

Then run with:

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

Connecting to the MCP Server

From Visual Studio Code (GitHub Copilot)

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

From Cursor (or other MCP clients)

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

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

3. Open the MCP panel in Cursor
4. The server should connect automatically

Usage Examples

Once connected, you can manage your server with 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?"
• "List all available workshop maps"
• "Host workshop map 1234567890" (replace with actual map ID)

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "cs2server" '{"url":"http://localhost:8080/cs2server/sse"}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

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

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

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

3. Restart Claude Desktop for the changes to take effect
