Main

A practical pattern is to pair “symptom → evidence → next action”:

• Symptom: “queries are slow” → Evidence: locks, bloat, vacuum stats, IO stats → Next action: index/vacuum/tuning.
• Keep the MCP server read-only at first (no writes) and rotate DB credentials like any other operational secret.
• For teams, prefer a dedicated DB role with least privilege; the agent only needs catalog/stat views for most diagnostics.
