RPG Maker MV Ultimate MCP

A Model Context Protocol server that lets an AI agent edit a real RPG Maker MV project on disk - database, maps, events, system - through 13 consolidated tools, validated against the actual engine so the output is coherent and playable - and it can reason about the project (validate references, explain why an event never fires, critique a map) via analyze_project.

People connecting gaming tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
