About Grey Hack MCP Server

What is Grey Hack MCP Server: GitHub Code Search & Greybel-JS Transpile?

Grey Hack MCP Server is a specialized development tool designed to streamline game modding and script creation for the Grey Hack game. It acts as a bridge between developers and the game's ecosystem by enabling code search, language conversion, and API validation through the Model Context Protocol (MCP). Compatible with tools like Cursor IDE, it simplifies tasks such as finding community code examples, converting proprietary GreyScript into JavaScript, and ensuring compatibility with official game APIs.

How to use Grey Hack MCP Server: GitHub Code Search & Greybel-JS Transpile?

Getting started involves three core steps:

Install dependencies like Node.js 18+ and acquire a GitHub API token for code search.
Configure the server via NPM installation or manual setup, then integrate it into your IDE (e.g., Cursor) using a JSON config file or manual settings.
Leverage built-in tools like search_greyhack_code to find examples, transpile_greyscript to convert code, and validate_greyscript for API compliance checks.

For example, to generate a port scanner script, run generate_greyhack_script port_scanner and tailor it to your needs.

Grey Hack MCP Server Features

Key Features of Grey Hack MCP Server: GitHub Code Search & Greybel-JS Transpile?

This server delivers four core capabilities:

GitHub Code Search: Instantly access community-developed Grey Hack scripts by searching repositories (e.g., "port scanner").
Greybel-JS Transpilation: Convert game-specific GreyScript into executable JavaScript for broader compatibility.
API Validation: Automatically flag syntax errors or deprecated methods against the latest Grey Hack 0.8.0 standards.
