MCP + A2A: Agent Interoperability Just Got Real Standards
Google's A2A protocol joined the Linux Foundation's Agentic AI Foundation — the same governance as Anthropic's MCP. Two protocols, one emerging standard for how agents talk.

On August 20, 2026, Google's A2A (Agent-to-Agent) protocol joined the Linux Foundation-directed Agentic AI Foundation — the same neutral home as Anthropic's Model Context Protocol (MCP). Agent interop is getting real, vendor-neutral standards.
Two protocols, two jobs
- MCP connects an agent to tools and data — a universal plug for context.
- A2A lets agents talk to other agents — delegation and coordination across systems.
Together they're becoming the TCP/IP layer of the agent world: the boring plumbing everything else builds on.
Why neutral governance matters
When a standard sits inside one company, everyone else hesitates to adopt it. Moving MCP and A2A under a foundation is what turns "a vendor's protocol" into "the industry's protocol" — and unlocks the ecosystem.
What to do now
If you're building agents, design against MCP for tools today. Watch A2A as multi-agent coordination matures. Betting on the open standards is how you avoid rebuilding when the dust settles.
