XARP

Human-First and Agent-Ready XR in Python

XARP is a Python toolkit for extended reality. It replaces lengthy build-deploy cycles with a fast prototype workflow, think Streamlit or Gradio for XR. XARP also augments AI agents with XR capabilities at runtime through callable tools and a Model Context Protocol.
