McpeTool
McpeTool is an offline utility for reading and writing Minecraft Bedrock Edition world data.
What McpeTool is
McpeTool is an 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, including work with key/value pairs in a world's LevelDB store. Database commands can list, retrieve, write, or delete those pairs. Level data commands retrieve or replace level.dat contents in JSON, YAML, hex dump, base64, or binary form, and the tool also supports JSON and YAML conversion for NBT data. The API accepts GET, PUT, and DELETE requests for database keys. McpeTool is intended as a basic access tool for people building other world editors, and runs on Linux, macOS, and Windows. It is free and MIT-licensed. It cannot be used while Minecraft is running the world, and it does not currently check whether input data is valid for the game. The maker describes it as a work in progress and advises backing up worlds before making changes.

Who it suits
McpeTool suits developers building Minecraft Bedrock world editors who need command-line or local API access to world data. It is less suited to people seeking a finished editor or changes while a world is running.
Verdict
McpeTool offers direct access to Bedrock world data for editor-building workflows. Back up worlds before editing, and use it only when the world is not running.
