The December 2025 AI Google Developer Expert (GDE) newsletter highlights two projects from William McLean. One demo shows how to run a Colab notebook directly inside the Antigravity environment, generating and executing code without leaving the app. Another project details deploying a MCP with Gemini CLI and Python on Google Cloud Run.

These projects streamline developer workflows. The Colab integration within Antigravity offers a novel way to leverage Google's hosted notebook environment. Meanwhile, the Cloud Run deployment guide provides a practical path for taking local MCP prototypes to a scalable production service, using streaming HTTP transport for testing.

The GDE program showcases practical applications of Google's AI and cloud tools. McLean's work demonstrates how developers can connect disparate services like Antigravity, Colab, and Cloud Run to build more efficient pipelines. The full newsletter offers deeper technical details for those building with these platforms.
