Blockbench vs Minecraft Development MCP Server

Blockbench is a free, open-source editor for making low-poly 3D models. Its tools support cuboid and mesh modeling, and users can create, edit, and paint textures in the program. Blockbench can generate a model's UV map and template, and connect to an external image editor or pixel-art program. For animation, it supports rigging, position, rotation, and scale keyframes, along with a graph editor. The built-in plugin store offers extensions such as tools, export formats, and model generators; users can also create plugins. Blockbench is available as a web app and on Windows, macOS, Linux, iOS, and Android. The project is licensed under the GPL. Its privacy policy says the software does not knowingly collect personally identifiable data, though it may collect anonymized usage information such as installation count. Local storage and cookies can remember preferences on a user's device. When users choose Model Sharing, model data is stored for the duration they select, and they can request earlier removal.

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.
