Agent Registry is generally available (GA)

Agent Registry is generally available (GA). Agent Registry is a centralized catalog for discovering and registering agents and Model Context Protocol (MCP) servers.

The following features are available in Agent Registry for the GA launch stage:

• API v1 and client libraries: The v1 version of the Agent Registry API is available. Cloud client libraries are available in C#, Go, Java, Node.js, PHP, Python, and Ruby. • A2A v1 support: Agent Registry supports Agent-to-Agent (A2A) protocol version 1.0, letting you explicitly declare transport endpoints and bindings inside the supportedInterfaces array, in addition to the existing 0.3 schema support. • Terraform support: Terraform scripts for Application Default Credentials (ADC) have graduated to General Availability. You can use Terraform to configure and manage your agents, MCP servers, endpoints, and bindings.

Known limitations:

• Access Transparency and Access Approval: Access Transparency logs, which provide visibility into when Google personnel access your content, and Access Approval controls aren't available for Agent Registry configurations. • Data Residency: If you configure the resource location constraint in your organization policy, Agent Registry enforces the constraint when you register a resource. However, detective controls for data residency compliance reporting are limited.
