Tutorial deploys remote MCP to GKE

While MCP is typically used locally over stdio, moving it to GKE allows enterprise scaling and security, though it introduces infrastructure overhead that might be overkill for simple developer tools.

• –Scalability: GKE allows MCP servers to autoscale based on demand, which is crucial for multi-agent systems.
• –Security: Remote deployment provides a centralized, secure environment for hosting API keys and proprietary logic rather than running them on local client machines.
• –Protocol Evolution: Moving from standard stdio transport to HTTP/gRPC transports enables seamless integration of remote servers across different networks.
• –Complexity vs. Utility: Setting up Kubernetes clusters and GKE deployments just to expose a few API tools increases the operations burden for developers compared to simpler serverless hosting like Cloud Run.
