Wiring the Agent Web

For AI agents to work together across companies and clouds they need a shared language, and a standards fight over whose language that will be is now underway.

What is it?

Agents need a shared language to work across companies and clouds, and a standards fight over whose language wins is now underway. A2A already sits inside three major clouds; MCP leads for tool access. Which protocol becomes the default, and who ends up owning it, stays open.

Why now?

Agents are only useful once they can call outside their own walls, and no vendor wants to be locked to a rival’s format. Regulators moved earlier than usual, coordinating security and identity work before the market settled. The layer usually fought over in private is being drafted in public.

Who’s building it?

Cloud platforms embedding rival protocols fast, plus a standards body now coordinating the rules that sit above them.

01 · The market
Who’s in it
Builders — the maintainer teams behind A2A and MCP alike.
Buyers — enterprises wiring agents together now, before any one protocol has fully won.
Gatekeepers — NIST and the standards bodies drafting the rules the market must follow.
What’s at stake
Whichever protocol clouds embed first tilts developer default choice by sheer convenience — infrastructure race, not feature race, decides the default.
Public standards work could pre-empt vendor lock-in before it forms.
Interoperability and tool-access may end up governed by separate winners.
What’s unsettled
Whether A2A and MCP stay complementary layers, or start to compete directly.
Whether NIST’s coordination speeds convergence, or just adds a slower track.
Whether early cloud embedding decides the winner before the standard is finished.
02 · How the demand matureda progression, not a timeline
Fragmentation
agents built per vendor, unable to call services outside their own walls.
Protocol adoption
A2A and MCP each cross a hundred-plus organisations within a year.
Platform embedding
clouds wire the leading protocols directly into Azure, Bedrock and Google Cloud’s core agent platforms.
Governed layer
NIST coordination turns a vendor scramble into a standard enterprises can build on.
03 · Where the market goesthe forks, not a prediction
→One standard or several — convergence gives every builder one target; a lasting split forces vendors to support both indefinitely.
→NIST’s initiative could harden into a binding rule, or stay coordination without any real teeth.
→Cloud platforms may quietly decide the winner just by which protocol they embed deepest and fastest.
→Interoperability and tool-access could keep separate leaders instead of one combined standard.
Underneath the standards race sits a demand question: does interoperability actually get used, or do agents stay walled inside one vendor’s platform regardless of which protocol wins.

The panel on this signal
They agreed on
–The interoperability layer is being built faster, and more publicly, than past infrastructure standards usually were.
–Cloud embedding currently matters more than the formal standards process.
–A2A and MCP currently solve different problems, not the same one.
The competition economist disagreed on
–Early integration of a given protocol into major cloud platforms creates default-adoption momentum ahead of any formal standards process; that deployment advantage may determine the outcome before a governing body’s ratification carries any practical weight.
