McpeTool vs Super-basic Minecraft Bedrock NBT Editor

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.

Super-basic Minecraft Bedrock NBT Editor is a free Windows utility for changing selected data in a Bedrock world’s level.dat file. It edits the world name, game mode, difficulty, seed, spawn position, common gamerules, ability flags, and raw NBT values in that file. The Re-enable Achievements action sets six listed experiment and creative-mode flags to zero, but commandsEnabled and experimentalgameplay may remain set to one and still block achievements. The editor does not modify the save’s db\ directory, identified as LevelDB data, and offers no region, terrain, entity, or batch editing. On launch, it automatically loads the first level.dat found under the current folder. Apply controls keep changes in memory until Save writes them to level.dat; each save creates a timestamped backup beside the world file. Start it with run_bedrock_nbt_editor.bat or run the Python script using python.\bedrock_nbt_editor.py. The repository lists an MIT license and no releases or packages. The Free plan costs nothing.
