Direct Communication Protocols for AI Agents: WebSockets, gRPC, and Pilot Protocol

The transition from isolated conversational models to collaborative artificial intelligence swarms requires a fundamental shift in how machines transmit data. When developers design multi-agent systems, they must select a transport mechanism that supports autonomous, low-latency, and reliable data exchange. While the Model Context Protocol standardizes an agent's local tool access and Agent-to-Agent frameworks define semantic payloads, routing those payloads across distributed network boundaries
