Grey Hack MCP Server

Write GreyScript for Grey Hack with example search, API validation and a transpiler behind the editor.

Code Generation, Scaffolding & Migration
Summary
GreyScript with a reference and a compiler at hand.

Grey Hack's scripting language has very little tooling around it. This puts example search, validation against a specific game version, and starter templates in the editor where the script is being written.

What it is

An MCP server for Grey Hack game development, aimed at Cursor and other MCP-capable editors. It searches GitHub for GreyScript examples, transpiles GreyScript to JavaScript through Greybel-JS, validates code against the official Grey Hack API for a version you name, and generates template scripts for common in-game tasks.

What you get
  • GreyScript examples found across public GitHub repositories
  • GreyScript converted to JavaScript through Greybel-JS
  • Code checked against the official Grey Hack API for a specific game version
  • Template scripts generated for common tasks, including port_scanner, password_cracker, file_browser and ssh_tool
Requirements

Node.js 18 or newer and an MCP-capable editor such as Cursor. The GitHub code search needs a GitHub API token: the launch command passes it as GITHUB_TOKEN through the Smithery CLI, or you set it as an environment variable on a manual configuration.
