About this Mod
PathFinder API is a dedicated command parsing API for Minecraft mods. It does not provide the suggestion UI itself; that is included in the Ultimate Backport Mod.
- Normal command suggestions do not require your mod to include the API.
- Dynamic suggestions require the API to be integrated into your mod.
This mod is needed by Ultimate Backport Mod and other mods depending on the API.
How it works:
- Command data can be generated easily at pathfinder.julianweinelt.de.
- Upload the generated JSON file on the website.
- Others can now easily download it in-game.
- PathFinder API handles parsing and prepares the commands for use in the game or UI.
Key Features:
- Lightweight parsing of commands, arguments, types, and custom suggestion lists.
- Works seamlessly with Ultimate Backport Mod for dynamic in-game suggestions.
- JSON-based workflow makes integration simple – no coding required for normal suggestions.
- Fully modder-friendly, easy to extend or integrate with your own tools.

Server lagging with PathFinder API – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if PathFinder API consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
