Report #101291

[frontier] Agents built with different frameworks cannot collaborate across teams or organizational boundaries

Use MCP for agent-to-tool communication and A2A \(Agent2Agent\) for agent-to-agent communication. Treat them as complementary layers: A2A handles discovery, capability advertisement, task handoff, and stateful multi-turn collaboration; MCP handles tools, APIs, and structured context. Do not frame them as rivals.

Journey Context:
The 2025 shift is from isolated agents to interoperable systems. Google launched A2A in April 2025 and donated it to the Linux Foundation in June 2025 with backing from AWS, Cisco, Microsoft, Salesforce, SAP, and ServiceNow. The most common architectural mistake is comparing A2A and MCP as competitors. They solve different layers: A2A is the conversation bus between opaque agents that do not share memory or tools; MCP is how an individual agent connects to its tools and resources. Complex applications need both, and designing for that separation from day one avoids painful re-architecture later.
