Blockception Minecraft Bedrock Development vs McpeTool

Blockception Minecraft Bedrock Development is a free extension for developing Minecraft Bedrock Addons and Minecraft Education Edition content. It supports .mcfunction, .json, .lang, and .molang files, with tools specific to each format. JSON features include validation, completions, hovers, signatures, code lens, code actions, and schemas. For .mcfunction, it provides completion, formatting, diagnostics, definition navigation, regions, symbols, syntax highlighting, and validation files; .lang tools include formatting, diagnostics, regions, symbols, and syntax highlighting. The extension can read .mcattributes, .mcdefinitions, and .mcignore project files. A setting adds Education Edition items, blocks, entities, and commands to suggestions and debugging. Other settings toggle diagnostics and selected completion options. During debugging, inline values can show variable lookups in mcfunction and Molang files, but are off by default. The extension is available for Windows, macOS, and Linux. Its earlier repository was archived on September 28, 2025, and points to Minecraft Bedrock Language Server as its successor.

McpeTool is a free, offline utility for reading and writing Minecraft Bedrock Edition world data. Its command-line interface and local HTTP API provide get, put, and delete operations. Database commands list, retrieve, write, and delete key/value pairs in a world’s LevelDB store. Level-data commands retrieve or replace level.dat contents using JSON, YAML, hex dump, base64, or binary formats. NBT data can be converted to JSON and YAML, and relevant commands accept or produce base64 and binary data. The API starts a local HTTP server and handles GET, PUT, and DELETE requests for database keys. The tool runs on Linux, macOS, and Windows and can be self-hosted or used through its API. It is MIT-licensed and intended as a basic access layer for people building more capable world editors. McpeTool cannot be used while Minecraft is running the world because LevelDB allows only one process at a time. The maker calls it a work in progress, says input validity is not currently checked, and advises backing up worlds before changes.
