Packwright MCP
A local-first Model Context Protocol server that allows agents to safely create, inspect, validate, test, and package Minecraft Java Edition datapacks and paired resource packs. It provides structured tools for guarded datapack creation, resource editing, vanilla-backed validation using Minecraft's real dispatcher, and deterministic ZIP builds without requiring unrestricted filesystem or shell access.
