Open-source, read-only PostgreSQL observability CLI for developers and AI agents. It analyzes native database statistics, reports health and query findings, and exposes deterministic diagnostics through MCP for agent workflows.

Free

What is pgbot?

pgbot is an open-source PostgreSQL observability CLI designed for developers and AI agent workflows. It connects to PostgreSQL in a read-only manner, analyzes native database statistics, and reports health and query-related findings. The tool also exposes deterministic diagnostics through an MCP server, making it useful for structured agent-based inspection tasks.

Key Features

  • Uses a read-only PostgreSQL connection to inspect native database statistics
  • Reports health findings across PostgreSQL databases without requiring write access
  • Analyzes query performance, locks, indexes, vacuum activity, replication, and database growth
  • Provides deterministic inspect and unused-index diagnostics through a stdio MCP server
  • Supports optional AI-powered ask and explain commands
  • Keeps core diagnostic workflows local while making AI assistance optional
  • Designed for both developer CLI usage and AI agent observability workflows

Best For

Developers who need quick PostgreSQL health checks from the command lineTeams building AI agent workflows that need deterministic database diagnosticsPostgreSQL users investigating query performance, locks, indexes, or vacuum behaviorEngineering teams looking for a free open-source observability helperDevelopers who want optional AI explanations without making AI required for core diagnostics

Pricing

pgbot is listed as a free tool. Because it is open source, users should review the project website or repository for current licensing details, installation requirements, and any optional service costs that may apply to AI-powered commands.

Pros & Cons

Pros

  • Free and open-source based on the provided tool information
  • Read-only database access model reduces the need for write permissions during inspection
  • Covers several PostgreSQL observability areas, including queries, locks, indexes, replication, vacuum activity, and growth
  • MCP support makes diagnostics accessible to AI agents in a structured way
  • Deterministic inspect and unused-index diagnostics can support repeatable workflows
  • Optional AI commands allow teams to use explanation features without depending on AI for every diagnostic

Cons

  • Focused specifically on PostgreSQL, so it is not a general-purpose database observability tool
  • May require PostgreSQL statistics to be available and properly configured for meaningful findings
  • CLI-first workflows may be less suitable for users who prefer dashboard-based monitoring
  • The provided information does not describe alerting, historical dashboards, or hosted team collaboration features
  • AI-powered ask and explain commands may require additional configuration not detailed in the provided information

Features

  • Reads PostgreSQL statistics with a read-only connection and reports health findings
  • Analyzes query performance, locks, indexes, vacuum activity, replication, and database growth
  • Exposes deterministic inspect and unused-index diagnostics through a stdio MCP server
  • Provides optional AI-powered ask and explain commands while keeping core diagnostics local

Languages

Known limitations

  • Works only with PostgreSQL and requires a read-only role with the documented monitoring permissions
  • The project labels its versioned JSON contract as beta, so integrations should pin and validate the schema
  • AI-powered ask and explain features require a configured OpenAI or Gemini key and explicit confirmation for outbound calls
