I've been building MXP, a high-performance protocol for AI agent communication.

Benchmarks (verified, reproducible):

256-byte message encode: 60ns (MXP) vs 2,262ns (JSON) Built-in trace IDs in every message (no OpenTelemetry instrumentation needed) Native streaming for LLM tokens Written in Rust, MIT/Apache-2.0 licensed, public domain spec.

Looking for feedback on:
