Throughout digital history, breakthroughs in interfaces—graphical, tactile, vocal, conversational—have reshaped how we interact with machines, driving new waves of adoption and transformation.
Now, a similar shift is happening at the system-to-system level.
Protocols like MCP (from Anthropic) and A2A (from Google) are reducing friction between AI agents. They redefine how systems discover each other, share capabilities, and coordinate actions. Just as RPA and APIs previously unlocked modular architectures by setting new standards, these emerging protocols could become the backbone of a truly agent-native digital ecosystem.
The fact that OpenAI and Google have just rallied around MCP is more than a technical alignment—it may be a turning point in the standardization of agentic infrastructure. Thanks Aurimas Griciūnas for this very insightful post on how MCP vs. A2A complement each other—for now—and how they together pave the way for more autonomous, interoperable ecosystems.
