MCP vs A2A: Two Protocols That Power Multi-Agent AI Stacks
MCP (Model Context Protocol) from Anthropic connects an AI agent to its tools, data, and APIs. A2A (Agent2Agent), now a Linux Foundation project, enables independent agents to delegate tasks to each other. The two protocols are complementary, with most production stacks in 2026 expected to run both.

The framing of MCP vs A2A as a competition misses the point—they solve different problems, and the real story is how developers will integrate both into agent architectures.
