MCP 服务器

RPG Maker MZ MCP Server

Enables AI agents to directly manipulate RPG Maker MZ projects through natural language commands, allowing creation and modification of game assets like items, weapons, enemies, maps, and plugins without manually editing game files.

README

RPG Maker MZ MCP Server 🎮✨

A powerful Model Context Protocol (MCP) server that allows AI agents (like Claude, Gemini, or Copilot) to directly manipulate RPG Maker MZ projects.

With this tool, you can ask your AI to "Create a fire sword", "Make a potion that regenerates mana", or "Generate a new map", and it will modify the game files directly!

🚀 Features

📦 Database Management (Full CRUD)

Create, Read, and Update almost any database asset:

Items: Create potions, keys, and hidden items. Support for HP/MP recovery and state application.
Weapons & Armors: Create equipment with stats, prices, and elemental effects.
Enemies: Define stats (HP/MP/ATK...), drops, and rewards (EXP/Gold).
States: Create status effects (e.g., Poison, Regen, Stun) with traits.
Actors & Classes: Create new heroes and classes with level curves and traits.
Skills: Define magic and special attacks.

🗺️ Map & World

Create Maps: Generate new map files (MapXXX.json) with metadata (size, tileset, BGM).
List Maps: See all maps in your project hierarchy.

🧩 Plugin & Resources

Plugin Installer: Automatically creates .js files in js/plugins and registers them in plugins.js.
Resource Scanner: List available graphics (img/), audio (audio/), and DLC packages.

🛡️ Safety First

Atomic Writes: Uses a SafeWriter to prevent data corruption.
Editor Sync: Automatically updates System.json version ID, forcing the RPG Maker MZ editor to reload data and preventing conflicts.
