Why This Matters

pgbot is a lightweight, open-source tool designed for easy, read-only access to PostgreSQL databases, enabling users to quickly assess performance, health, and schema issues through plain English queries and AI-powered explanations. Its flexible deployment options include direct connections or private agents, making it suitable for various environments without exposing sensitive data. This innovation simplifies database management, empowering both technical and non-technical users to maintain optimal database health efficiently.

Key Takeaways

Connect your Postgres. Get answers, not dashboards: what's healthy, what's broken, and what to fix first.

pgbot pgbot inspect --full pgbot indexes pgbot tables help pgbot ask "why is it slow?"

Two paths to the same place: connect directly over the wire, or run the agent next to a database that never leaves your network.

Read-only access, open-source agent, and support for private deployments without exposing your database publicly.

Connect directly to public databases or use the pgBot Agent for private environments like Docker, Kubernetes, and internal servers.

Ask pgBot questions in plain English and get summaries, explanations, and recommendations based on real database signals.

Connect any PostgreSQL database and get visibility into performance, queries, health, schema, and changes — with AI-powered explanations.

MCP — use pgbot as an agent tool

pgbot mcp speaks the Model Context Protocol on stdio, so an AI agent can call pgbot as a read-only tool. It exposes deterministic tools only — inspect (full findings as JSON) and unused_indexes — and lets the connected model do the explaining. No Gemini key involved: the agent reasons over the same findings the CLI computes.

Add it to any MCP client (Claude Desktop/Code, Cursor, …)
