In their own words
Minecraft Development MCP Server
Minecraft Development MCP Server gives AI assistants and development tools ways to inspect Minecraft Java source and mods. It can download, decompile and remap versions on first use, then cache the results for searching and analysis. Its 21 tools cover source code, mappings and registry data, validation, and mod analysis. Developers can validate Mixin code and loader-specific access rules, inspect mod JAR metadata and dependencies, and compare versions at class and AST levels to identify changes. Mapping namespaces include Yarn, Mojmap, Intermediary and obfuscated names. Yarn is available for Minecraft 1.14–1.21.11; versions 26.1 and later support Mojmap, while Yarn is unavailable. Setup is documented for Claude Desktop and Claude Code, with HTTP transport and a standalone CLI also available. Installation options include global npm, npx or a source build. It is free and MIT-licensed, and runs on Windows, macOS and Linux/WSL. Node.js 18 or newer is required, and Java 17 or newer is needed for decompilation and remapping. Its local cache uses about 400–500 MB per Minecraft version.
Neo-Loom
Neo-Loom is a free Gradle plugin for Minecraft mod development environments using NeoForge or MinecraftForge. It is a fork of Fabric Loom and is heavily based on Architectury Loom. Implemented support includes NeoForge 1.21+ and MinecraftForge 1.20.1+. The plugin supports multi-loader projects, dependency management, client and server scope, and dedicated server support. It provides run configurations for NeoForge and MinecraftForge covering server data, client data, and game test server environments. Neo-Loom supports Jar-in-Jar packaging, converts ClassTweaker or AccessWidener files to AccessTransformer format, and supports publishing and consuming ModDevGradle-compatible Access Transformers and Interface Injections. Devlaunch is listed as implemented. Setup uses the Fabric and RelativityMC Maven repositories and the Gradle Plugin Portal, with plugin IDs shown in the README. The repository is MIT licensed and points users to Discord for support. Listed unfinished work includes JUnit, production launch tasks, and split-source, client-only, and server-only setups for (Neo)Forge.
