Google's Agent-to-Agent (A2A) protocol enables autonomous agents to discover, authenticate, and collaborate with each other across organizational boundaries. These articles explore A2A implementation patterns, broker-based coordination, and how A2A complements MCP for inter-agent communication in production multi-agent systems. Topics include agent card discovery, task lifecycle management, and secure cross-platform agent orchestration. Each post includes working Go code examples demonstrating real-world A2A integration scenarios.

This lesson hosts one specialized Foundry agent over the A2A protocol, publishing an agent card the client can discover.
Host one Foundry agent over A2A: newMux pins the card interface URL, wraps the agent in an a2aprovider executor, and serves the card plus JSON-RPC routes.
This lesson builds a Foundry host agent that discovers remote A2A agents by their cards and calls each one as a tool.
A Foundry host agent resolves remote A2A agent cards and turns each remote agent into a callable tool with agenttool.New over the a2aprovider.
The reference architecture distinguishes request-based and message-driven agent communication. For in-process orchestration, the workflow IS the broker — and A2A is just the wire format.
Running agents on Cloud Run, exposing via A2A, and wiring into production systems.
Deploy Microsoft Agent Framework multi-agent systems on Cloud Run with A2A agent-to-agent communication, autoscaling, load balancing, and production observability dashboards.
Google's A2A spec standardises how agents talk to other agents (not just tools). The Go client is small; the conceptual shift is what matters.
