ARC Protocol Documentation
Agent Remote Communication (ARC) Protocol — A stateless RPC protocol for multi-agent systems with quantum-safe hybrid TLS encryption and single-endpoint multi-agent routing.
Complete infrastructure for agent communication, discovery, and routing
ARC Protocol
Communication Layer
Stateless RPC protocol that solves multi-agent deployment complexity with intelligent routing, quantum-safe encryption, and end-to-end workflow tracing.
ARC Compass
Agent Search Engine
Intelligent ranking system that finds optimal agents through advanced algorithms, semantic extraction, and capability matching based on input requirements.
ARC Ledger
Discovery Registry
Centralized registry maintaining comprehensive agent cards, capabilities, endpoints, and metadata enabling efficient discovery and understanding of agent ecosystems.
Core Features
Single Endpoint
Deploy multiple agent types on one endpoint with intelligent routing
Quantum-Safe
Hybrid TLS using X25519 + Kyber-768 (FIPS 203 ML-KEM)
Workflow Tracing
End-to-end observability with automatic traceId propagation
Stateless Design
Clean RPC-style method invocation with no session state
Real-time Streaming
Server-Sent Events (SSE) for chat responses
Multi-Agent Routing
Built-in routing via requestAgent and targetAgent fields
