I built pgbot because I often needed a quick explanation of what was happening inside a database without first deploying a dashboard, collector, telemetry stack, or separate database.

pgbot is an open-source 5.9 MB Go binary that connects directly to PostgreSQL and returns useful findings in seconds:

pgbot inspect — database health pgbot queries — expensive queries pgbot indexes — risky and unused indexes pgbot ask — answers for humans and agents MCP — lets coding agents inspect PostgreSQL directly

The diagnostic findings are computed deterministically in Go. They are not invented by an LLM.

pgbot is also read-only by design: it inspects the database but never applies changes. An agent can explain and prioritize the evidence, but it cannot silently modify production through pgbot.
