How I dropped LLM latency from 500ms to 0ms in real-time physics loops

If you’ve tried to put an LLM in charge of a 60fps physics loop (robotics, MuJoCo, game NPCs), you’ve hit the wall. The "Brain-Pull" model—where the brain has to micromanage every tool-call—is just too slow. Physics doesn't wait for an API response. I just open-sourced a "Body-Push" protocol called SCP (Spatial Context Protocol) and an orchestrator called Plexa to solve this. The Problem: The "Brain-Pull" Bottleneck Standard tool-calling (like MCP) is passive. The Brain asks, the Body waits....
