Search CubeCobra for cubes (public)
AI agents call search_cubes to retrieve information from CubeCobra MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries publicly available cube data from CubeCobra without any ability to create, modify, delete, or execute operations. It presents minimal risk as it only searches and returns existing public information. Misuse would be limited to information disclosure concerns rather than system compromise or data loss.
From the tool's definition Tool performs a public search operation with no parameters that modify data. The description explicitly states "Search CubeCobra for cubes (public)" indicating a read-only query operation.
