Agent-to-Agent Protocol (A2A) in Practice
As agent systems evolve beyond isolated workflows, the real bottleneck becomes how agents discover, communicate, delegate, and reason across boundaries.
This session is a technical deep dive into Agent-to-Agent (A2A) protocol; how it works conceptually, how it’s implemented inside Lyzr Agent Studio, and how it differs from Model Context Protocol (MCP) at a systems level.
We’ll move past abstractions and focus on interfaces, message flows, orchestration logic, and real usage patterns.
What we’ll cover
1. A2A Protocol- first principles
What “agent-to-agent” actually means in production systems
Task delegation vs message passing vs orchestration
Stateless vs stateful agent communication
2. A2A inside Lyzr Agent Studio (internals)
Agent interfaces and invocation contracts
How agents discover and call other agents
Execution flow, response handling, and failure modes
Guardrails for loops, hallucinated calls, and runaway delegation
3. Live A2A use case
One agent delegating subtasks to multiple specialized agents
Aggregation and reasoning over agent outputs
Where orchestration lives vs where autonomy begins
4. MCP vs A2A- architectural differences
MCP as a model: tool/context interface
A2A as an agent: agent coordination layer
When MCP breaks down for multi-agent systems
When A2A is overkill
Who should attend
Developers building multi-agent systems
Engineers working on agent orchestration frameworks
Platform teams evaluating A2A vs MCP
Anyone moving from single-agent demos to production-grade agent networks
