PlayerCoordsAPI

A lightweight Fabric mod that exposes your Minecraft player coordinates via a local HTTP API.

📋 Overview

PlayerCoordsAPI provides real-time access to your Minecraft player coordinates through a simple HTTP endpoint. This enables external applications to track your position without needing to read Minecraft's memory or capture the screen.

✨ Features

• Lightweight HTTP server running only on localhost providing your coordinates
• Client-side only - no server-side components needed
• Works in singleplayer and multiplayer
• Mod menu integration allowing you to enable/disable the API, change its port, and configure requests with or without an Origin header

🚀 Installation

1. Install Fabric Loader
2. Download the latest playercoordsapi-x.x.x+mcx.x.x.jar from the releases page
3. Place the jar in your .minecraft/mods folder
4. Launch Minecraft with the Fabric profile

⚙️ Configuration

The API is read-only and only accepts loopback connections such as 127.0.0.1 and ::1. From Mod Menu, you can configure:

• Whether the API is enabled
• Which port it listens on (default: 25565)
• How requests without a CORS Origin header are handled
• How requests with a CORS Origin header are handled

Requests with an Origin can be handled in three different modes:

• Allow all
• Local origins
• Whitelist

In Whitelist mode, you can configure each allowed origin with a scheme, host/IP, and optional port.
