Muestra los nombres de todas las bases de datos disponibles en el servidor
AI agents call listar_bases_de_datos to retrieve information from Modular MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that lists database names. It has no side effects, does not modify data, and does not execute code or trigger external operations. The only potential concern is information disclosure about database structure, which warrants a low severity rating rather than higher categories.
