获取表的样本数据（默认前5行），快速了解数据内容
AI agents call get_table_sample 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 sample rows from a table with no modification, deletion, or execution of arbitrary code. It is a straightforward data retrieval operation with minimal blast radius—an AI agent using it can only view a small fixed sample of data. No write, destructive, financial, or execute capabilities are present.
