WHAT IT DOES

What pg_analyze_query_indexes does on PostgreSQL MCP Server

AI agents invoke pg_analyze_query_indexes to trigger actions in PostgreSQL MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why pg_analyze_query_indexes is rated High

EXPLAIN ANALYZE actually executes the query against the database (not just plans it), which constitutes execution with real side effects on server resources. It runs the query to gather actual timing and row statistics, distinguishing it from a pure read/metadata operation. Misuse could execute expensive queries, causing performance degradation.
