What McpeTool is

McpeTool is a free, offline utility for reading and modifying Minecraft Bedrock Edition world data. Its command-line interface and local HTTP API provide get, put, and delete operations. Database commands can list, retrieve, write, or remove key/value pairs in a world’s LevelDB store. Level data commands retrieve or replace level.dat contents in JSON, YAML, hex dump, base64, or binary formats; the tool also supports JSON and YAML conversion for NBT data. The API runs a local HTTP server and accepts GET, PUT, and DELETE requests for database keys. McpeTool is intended as a basic access tool for people building other world editors and is available for Linux, macOS, and Windows. It is MIT-licensed. The maker describes the project as a work in progress and advises backing up worlds before changing them. It cannot be used while Minecraft is running the world, because LevelDB permits only one process at a time. The tool also does not currently check whether input data is valid for the game.

Getting started

Open the McpeTool repository on GitHub.

Use the command-line interface or run the local HTTP API.
Work with a Minecraft Bedrock world directory and its LevelDB store or level.dat data.
Back up the world before modifying it.

Verdict

McpeTool provides offline access to Bedrock world data through both a CLI and local HTTP API. Its current lack of game-data validation and inability to work on an active world make backups and careful use important.
