The post collects 11 protocols in the modern AI agent communication stack and groups them by role, from native agent protocols to foundational standards.
The list includes MCP, A2A, ACP, AG-UI, ANP, LSP, OpenAPI, OAuth 2.0, OpenTelemetry AI, JSON Schema, and JSON-RPC 2.0. The accompanying guide explains what each protocol does, where it fits, and when to use it, making the post a practical reference for people building agent systems.
