### The Feature

Please support GCP Managed MCP Servers natively. Currently we need a custom auth proxy running as sidecar in GKE cluster to authenticate with GCP managed remote MCP servers. Not clean.

### Motivation, pitch

Support for native GCP Managed MCP Servers would simplify the setup for using those MCP servers in GKE.
