Debugging Deployments with Gemma 4B, TPU v6e-1, MCP, and Antigravity CLI

Deploying Gemma 4 on Google Cloud TPUs gets easier with a Python MCP server that manages the full lifecycle — provisioning, observability, and benchmarking — through Antigravity CLI. The guide walks through setting up stdio transport, validating the MCP connection locally, then scaling to TPU deployments on Cloud Run, including cost comparisons across 2B and 12B model variants on v6e-1 and v6e-4 chip configurations.
