WHAT IT DOES

What pg_stats_moving_avg does on PostgreSQL MCP Server

AI agents call pg_stats_moving_avg to retrieve information from PostgreSQL MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why pg_stats_moving_avg is rated Low

This tool retrieves and computes aggregate statistics from a numeric column using window functions. It does not create, modify, delete, or execute arbitrary code—it only queries and calculates results. The blast radius of misuse is minimal: at worst, an agent could request expensive computations, but no data integrity or system state is affected. This is a straightforward Read operation.

From the tool's definition Tool description: 'Calculate moving average (AVG OVER sliding window) for a numeric column.' The AVG OVER clause is a SQL analytic function that computes aggregate statistics over a window of rows without modifying data.
