GCP MCP

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

• src/gcp_mcp/gcp_modules/compute/tools.py:574-623 (handler)

  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.

  @mcp.tool()
  def create_snapshot(project_id: str, zone: str, disk_name: str, snapshot_name: str, description: str = "") -> str:

• src/gcp_mcp/server.py:39-39 (registration)

  Registers the compute tools module, which includes the create_snapshot tool, by calling its register_tools function with the MCP server instance.

  compute_tools.register_tools(mcp)

• src/gcp_mcp/gcp_modules/compute/tools.py:6-6 (registration)

  The function that defines and registers all compute tools, including create_snapshot via decorators.
