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.
