Introduction to the topic Building Strands Agents with a few lines of code: Agent-to-Agent A2A Communication explained in Spanish for developers and companies
Agent-to-agent A2A communication represents the next evolution in automation with artificial intelligence where multiple specialized agents collaborate to solve complex problems. With the Strands Agent framework it is possible to create multi-agent systems that coordinate tasks and delegate responsibilities beyond what an individual agent can do.
What is A2A and why it matters Understanding the A2A protocol helps design architectures that enable agent discovery, structured message exchange, and collaboration in distributed workflows. This enables use cases such as multi-agent workflows, agent marketplaces, cross-platform integrations, and distributed AI systems.
MCP vs A2A MCP Model Context Protocol connects agents with tools APIs and resources through structured inputs and outputs. A2A facilitates dynamic communication between agents as peers. In short MCP provides tools to agents and A2A allows agents to collaborate with each other.
Typical A2A architecture A common scenario is a layered architecture where a primary agent initiates communication and delegates tasks, secondary agents receive tasks and respond, an MCP server offers access to data and tools, and an A2A layer manages the protocol and message format.
Practical example of three components In the example shown in the repository https://github.com/elizabethfuentes12/strands-agent-samples an architecture is proposed with an MCP server that offers employee data, an Employee Agent that connects to the MCP server and publishes its capabilities via A2A, and an HR Agent that acts as a gateway for user queries and coordinates the invocation of specialist agents.
Summary of main components MCP server exposes tools such as get_skills and get_employees_with_skill to query skills and employees. Employee Agent uses an MCP client and publishes its capabilities through an A2A server. HR Agent creates a public API that receives user questions and uses an A2A tool provider to discover and query known agents.
Quick step-by-step to test the example Clone the repository https://github.com/elizabethfuentes12/strands-agent-samples create and activate a virtual environment python -m venv .venv source .venv/bin/activate install dependencies pip install -r requirements.txt start the MCP server then the Employee Agent and finally the HR Agent and make HTTP requests to the HR Agent query endpoint to get responses coordinated by multiple agents.
Best practices in A2A communication Define clear responsibilities for each agent implement robust error handling and fallback mechanisms standardize message formats between agents monitor response times and success rates and consider validation and security in exchanged messages. Test both agents individually and their interactions in real scenarios.
Deployment and performance considerations For multi-agent systems in production it is recommended to optimize latencies, use appropriate transports for A2A such as streamable HTTP or websockets, size models and caches, and use cloud services for high availability and automatic scaling.
Integration with cloud services and enterprise tools Agents can integrate with aws and azure cloud services for storage, serverless functions, and orchestration. It is also common to expose capabilities to business intelligence tools such as power bi to visualize results, and connect to data pipelines to feed AI models and agents.
Next steps and improvements In future developments advanced coordination patterns, integration with external APIs, performance optimization for multi-agent systems, and automated deployments with infrastructures such as IaC can be explored. Experiment with different agent and tool configurations to define the balance between autonomy and centralized control.
