WHAT IT DOES

What cloudsync_list_buckets does on Nasbridge

AI agents call cloudsync_list_buckets to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why cloudsync_list_buckets is rated Low

This tool queries and returns information about remote cloud storage buckets associated with a given credential. It performs a read-only operation with no side effects, matching the Read category definition of retrieving or querying data. The severity is low because misuse would only expose metadata about available buckets, not compromise data integrity or enable destructive operations.

From the tool's definition Tool name includes 'list' and description states 'List remote buckets' — both indicate data retrieval with no modification or deletion.
