[NeoFS] List containers owned by an address
AI agents call neofs_get_containers to retrieve information from Neo N3 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a listing/query operation to retrieve container information associated with a blockchain address. It does not create, modify, delete, execute code, or transfer assets. The 'list' action is characteristic of Read category tools that have minimal security risk.
From the tool's definition Tool name 'neofs_get_containers' and description 'List containers owned by an address' indicate a query operation that retrieves data without modification or side effects.
