Agent Registry is generally available (GA).

The following are features 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.

The following known issues affect Agent Registry:

• Search location filtering: When calling the SearchAgents or SearchMcpServers APIs for the global location, the results might incorrectly include resources from us and eu multi-regions.
• URN mismatch: When searching for agents or MCP servers in the Google Cloud console, the page might display an invalid URN format in the search results list.
• Console error: Users who actively switch between tabs on the MCP server details page in the Google Cloud console might encounter an unexpected throttling error.
