What getTableStats does on Postgresql

AI agents call getTableStats to retrieve information from Postgresql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why getTableStats needs a policy

This tool queries PostgreSQL system catalogs (pg_stat_user_tables or similar) to retrieve table metadata and statistics. It performs no write, delete, execute, or financial operations—it only reads and reports statistics. Even in a context where other tools on the server can execute destructive operations (deleteRows, dropIndex, executeDDL), this specific tool is purely informational.

From the tool's definition Tool retrieves 'detailed statistics' including 'live/dead row counts', 'timestamps', and 'modification count' with no description of modification or deletion of data. The verb 'Get' and phrase 'Useful for monitoring' indicate a diagnostic query-only operation.
