MC Local API
by luisafk
MC Local API gives Minecraft Java clients a local HTTP REST interface that other programs can use to query the running game.
What it does
Once the mod is loaded, the client exposes a REST API on the local machine, so tools outside the game can read its state over HTTP. The author notes a ChunkBase Tracker script built on it, which updates a ChunkBase seed map automatically as the player moves. The API works on the client alone, so no server install is needed. It is published for Fabric only, for 1.21.8 – 26.2, and the latest file is 0.0.9 for 26.2. The code is not open source and is released under All rights reserved.
