Tool governance in Vertex AI Agent Builder with the new Cloud API Registry integration

Hi everyone!

Vertex AI just launched the Cloud API Registry integration for Vertex AI Agent Builder, which acts as a centralized catalog for Google Cloud and your own MCP servers.

I’m sharing a guide with code on using the new Cloud API Registry on Vertex AI. It lets you deploy agents that connect to services like BigQuery using MCP without writing wrapper code.

What you will learn in the tutorial:

  1. Find Tools: How to use gcloud beta api-registry mcp servers list to discover tools.
  2. Code the Agent: How to use the ApiRegistry class to auto-discover tools like run_sql.
  3. Deploy the Agent: How to deploy the agent on Vertex AI Agent Engine.

Happy building!
