获取表的统计信息，包括行数、数据大小、索引大小、列基数
AI agents call get_table_stats 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 retrieves statistical metadata about tables (row counts, sizes, cardinality) without creating, modifying, deleting, executing, or moving money. It is a pure information retrieval operation with no side effects, fitting the Read category. The minimal blast radius (exposure of non-sensitive schema statistics) warrants low severity.
From the tool's definition Tool name 'get_table_stats' and description stating it retrieves 'table statistics including row count, data size, index size, column cardinality' — all read-only metadata queries with no modification or deletion capability.

get_table_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_table_stats rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
