create_snapshot
Generate a snapshot of a Compute Engine disk in Google Cloud Platform. Provide project ID, zone, disk name, and snapshot name to save disk data for backup or replication.
Instructions
Create a snapshot of a Compute Engine disk.
Args:
project_id: The ID of the GCP project
zone: The zone where the disk is located (e.g., "us-central1-a")
disk_name: The name of the disk to snapshot
snapshot_name: The name for the new snapshot
description: Optional description for the snapshot
Returns:
Status message indicating whether the snapshot was created successfully

Implementation Reference
- The core handler function for the 'create_snapshot' MCP tool. It uses the Google Cloud Compute API to create a snapshot from a specified disk, waits for completion, and returns success or error message.
