Phase 0: Why Multi-Agent, and the Primitives · ~120 minutes · TypeScript
Communication Protocols
Agents that can't speak the same language aren't a team. They're strangers shouting into the void.
Hiring signal: Can operate communication protocols in production
What you will learn
- Implement MCP tool discovery and invocation so agents can use tools exposed by external servers
- Build an A2A agent card and task endpoint that allows one agent to delegate work to another over HTTP
- Compare MCP (tool access), A2A (agent-to-agent), ACP (enterprise audit), and ANP (decentralized trust) and explain which protocol solves which problem
- Wire multiple protocols together in a single system where agents discover tools via MCP and delegate tasks via A2A
