GreyHack Tools MCP server

The Grey Hack MCP Server is a specialized server that enhances Grey Hack game development through the Model Context Protocol (MCP). It integrates with Cursor IDE and other MCP-compatible tools to provide code search, transpilation, validation, and script generation capabilities for Grey Hack development.

Installation

Prerequisites

• Node.js 18+ installed
• Cursor IDE or another MCP-compatible editor
• GitHub API token (for code search functionality)

Install from NPM

npm install -g @chromewillow/greyhack-mcp-server

Manual Installation

Clone the repository and install dependencies:

git clone https://github.com/chromewillow/greyhack-mcp-server.git
cd greyhack-mcp-server
npm install
npm run build

Configuration

Setting up with Cursor IDE

Using Configuration File

Create a .cursor/mcp.json file in your workspace with the following content:

{
  "mcpServers": {
    "@greyhack-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@smithery/cli@latest",
        "run",
        "@chromewillow/greyhack-mcp-server",
        "--config",
        "{\"GITHUB_TOKEN\":\"your-github-token-here\"}"
      ]
    }
  }
}

Manual Configuration in Cursor

1. Open Cursor settings (Cmd/Ctrl + ,)
2. Navigate to Features → MCP
3. Click "+ Add New MCP Server"
4. Enter the following details:
   • Name: greyhack-mcp-server
   • Command: npx
   • Arguments: -y @smithery/cli@latest run @chromewillow/greyhack-mcp-server
   • Environment Variables: GITHUB_TOKEN=your-github-token-here

Using the MCP Server

GitHub Code Search

Find Grey Hack code examples from GitHub repositories:

Use the search_greyhack_code tool to find examples of port scanners in Grey Hack

Greybel-JS Transpilation

Convert GreyScript code to JavaScript for easier analysis:

Use the transpile_greyscript tool to convert this Grey Hack code to JavaScript:
get_shell.host_computer.File("/home/user/test.txt")

GreyScript API Validation

Validate your code against the official Grey Hack API:

Use the validate_greyscript tool to check if this code is valid in Grey Hack 0.8.0:
router = get_router
ip = router.local_ip

Script Generation

Generate template scripts for common game tasks:

Use the generate_greyhack_script tool to create a port scanner for Grey Hack 0.8.0

Available Script Templates

The server can generate several types of script templates:

• port_scanner: Network port scanning utility
• password_cracker: Password cracking tool
• file_browser: File browsing and manipulation utility
• ssh_tool: SSH connection utility
• custom: Custom script template (requires description)

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 "greyhack-mcp-server" '{"command":"npx","args":["-y","@smithery/cli@latest","run","@chromewillow/greyhack-mcp-server","--config","{\"GITHUB_TOKEN\":\"your-github-token-here\"}"]}'

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": {
        "@greyhack-mcp-server": {
            "command": "npx",
            "args": [
                "-y",
                "@smithery/cli@latest",
                "run",
                "@chromewillow/greyhack-mcp-server",
                "--config",
                "{\"GITHUB_TOKEN\":\"your-github-token-here\"}"
            ]
        }
    }
}

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": {
        "@greyhack-mcp-server": {
            "command": "npx",
            "args": [
                "-y",
                "@smithery/cli@latest",
                "run",
                "@chromewillow/greyhack-mcp-server",
                "--config",
                "{\"GITHUB_TOKEN\":\"your-github-token-here\"}"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
