Suggest appropriate scope (folder/cloud/organization) for resource queries
AI agents call suggest_query_scope to retrieve information from Yandex Cloud MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only suggests or recommends a scope parameter; it does not execute queries, modify resources, delete data, or move money. It is purely informational guidance for query construction. Classification as Read reflects that it accesses or provides information with no side effects.
From the tool's definition Tool name is 'suggest_query_scope' and description states it 'suggest[s] appropriate scope for resource queries'. The server is described as 'Read-only MCP server' with sibling tools that are all read operations (get_*, clear_credentials).
