获取MySQL服务器中所有数据库列表
AI agents call get_databases to retrieve information from MySQL 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 returns metadata about existing databases without creating, modifying, deleting, executing code, or committing financial transactions. It is a non-destructive read operation with minimal blast radius—an AI misuse would only expose database names, not alter system state.
