The MCP-PostgreSQL-Ops server is a professional MCP server designed to provide PostgreSQL operations, monitoring, and management via natural language queries. It supports PostgreSQL versions 12-17 and offers comprehensive database analysis, performance monitoring, and intelligent maintenance recommendations. Most features operate independently, with advanced query analysis enhanced when optional extensions pg_stat_statements and pg_stat_monitor are installed. The server enables zero-configuration operation with automatic version detection and read-only access for safe production usage, including RDS/Aurora compatibility. It supports multi-database analysis across multiple PostgreSQL databases, cross-database query capabilities, and schema/relationship discovery. The architecture provides a suite of tools for real-time statistics, IO, bloat detection, VACUUM analysis, replication/WAL status, locks, and more. It exposes tools via a CLI or HTTP API (OpenWebUI) with a flexible MCP transport and authentication options (Bearer token for streamable-http). It is designed to be developer-friendly and easily extensible with new MCP tools. Installation can be via PyPI or from source; example flows include local testing with a built-in test container. The README also includes a compatibility matrix and detailed prerequisites for extensions and PostgreSQL configuration.
