Agent Registry integration support for MCP metadata (Preview)

## Feature Feature **Agent Registry integration support for MCP metadata (Preview)** API hub now includes a managed integration with Agent Registry to automatically synchronize Model Context Protocol (MCP) servers and tools metadata. This feature enables AI agents to discover and interact with the APIs registered in your hub without manual configuration. This feature is in [Public Preview](https://cloud.google.com/products#product-launch-stages). For more information, see [Manage Agent Registry integration](https://cloud.google.com/apigee/docs/apihub/manage-agent-registry-integration). ## Fix Fixed **Correction to [April 2, 2026 release note: Deployment disruption for Apigee Drupal Portal via Google Cloud Marketplace](#April%5F02%5F2026)** For the deployment disruption announced on April 2, the announcement noted that deployment and management functionality using Google Cloud Deployment Manager would definitely be unavailable during the transition. This statement is incorrect. The functionality _might_ be unavailable. See the [Known issue](https://cloud.google.com/apigee/docs/release/known-issues#495305258) for more information. ## Change Change On April 6th, 2026, we released an updated version of Apigee. This change introduces the new `apigee.coreServiceAgent` IAM role for Apigee. **Effective immediately, use `apigee.coreServiceAgent` instead of the`apigee.serviceAgent` role.** For information on the new role, see[apigee.coreServiceAgent](https://cloud.google.com/iam/docs/roles-permissions/apigee#apigee.coreServiceAgent).
