A2A and MCP Form the Agent Gateway
Observed now: A2A v1.0 is a stable, production-ready standard for agent-to-agent communication, while MCP now has current protocol documentation and stable enterprise-managed authorization. Together they establish a practical gateway layer between agent coordination and tool access. Complete translation across every enterprise policy system remains unsolved.
Why this idea is here
What the evidence establishes.
The A2A community documents v1.0 with version negotiation, signed Agent Cards, multi-tenancy, and multiple bindings; MCP documents interoperable tool and data connections plus stable enterprise-managed authorization. These current sources support a protocol gateway layer, not universal policy translation.
