Google's A2A Protocol Joins AAIF, Consolidating the Agent Economy's Protocol Layer Under One Roof

My take: Google just transferred its A2A (Agent-to-Agent) protocol to the Agentic AI Foundation (AAIF), the same Linux Foundation-directed neutral body that already governs Anthropic's Model Context Protocol (MCP). In less than a year, AAIF grew from fewer than 40 founding members to more than 250, including AWS, Anthropic, Block, Bloomberg, Cloudflare, Google, Microsoft, and OpenAI.

This matters because open standards are what separates a growing ecosystem from a fragmented one. MCP defines how an agent connects to tools and data (the vertical layer). A2A defines how two agents coordinate with each other (the horizontal layer). Both together under neutral governance means developers can build agents that work across any platform, not just the one from their vendor.

For anyone already building with AI agents, or planning to, this news reduces the risk of betting on technology that could end up locked into a proprietary silo.

Are you building on open protocols, or do your agent tools depend on a single platform?
