列举 TOS 存储桶
AI agents call tos_list_buckets to retrieve information from TOS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and lists existing buckets without creating, modifying, deleting, or executing operations. It is a read-only retrieval operation with minimal blast radius—an AI agent listing buckets cannot cause data loss or unintended side effects. The severity is low because listing buckets exposes metadata but does not alter state.
From the tool's definition Tool name 'tos_list_buckets' and description '列举 TOS 存储桶' (list TOS buckets) indicates retrieval of bucket inventory with no modification of data.
