The core argument: A2A is not dead, but it is also not universally necessary. The key distinction is between tool integration (MCP's job) and agent delegation (A2A's job). A2A becomes valuable when agents are independently deployed, owned by different teams, built on different frameworks, and need structured task lifecycle management across real boundaries. For small teams and simple workflows, MCP plus good tooling is sufficient. The recommended 2026 architecture is layered: MCP below for tool access, A2A above for agent-to-agent collaboration. Security remains the biggest unresolved challenge, requiring strong agent identity, scoped authorization, audit logs, and policy enforcement. The practical advice: start with MCP, design clean agent boundaries, and adopt A2A only when those boundaries become real deployment or ownership constraints. ## Full article daily.dev links to this article rather than hosting it.
