Parameter	Type	Required	Description
`zone`	string	Yes	Required. The zone of the instance group managers.
`project`	string	Yes	Required. Project ID for this request.
`pageSize`	integer	—	Optional. The maximum number of instance group managers to return.

RISK

Why list_instance_group_managers is rated Low

This tool retrieves and queries infrastructure metadata without creating, modifying, deleting, or executing any operations. It is a purely informational API call that reads existing resource state. The blast radius of misuse is minimal—an agent could only gather information about existing MIGs, not alter or delete them.

From the tool's definition Tool description states it 'Lists Compute Engine managed instance groups' and returns details like name, ID, instance template, base instance name, target size, status and creation timestamp.
