The Micro Agent Communication Protocol (uACP)

This document specifies the Micro Agent Communication Protocol (µACP), a resource-efficient messaging protocol for autonomous agents operating on resource-constrained Edge and IoT devices (including Class 1 and Class 2 devices per [RFC7228]). Existing agent communication protocols assume unbounded computational and energy resources; µACP provides bounded resource consumption guarantees with deterministic memory bounds (8-byte header, up to 1024-byte TLV region, up to 65535-byte payload) and bounded processing time per message, while maintaining expressiveness sufficient for finite-state coordination patterns. The protocol defines four core message types, a fixed 64-bit header, TLV-based extensibility, and mandatory OSCORE security binding for operation in adversarial environments.
