call518/MCP-PostgreSQL-Ops
MCP-PostgreSQL-Ops is a Model Context Protocol server aimed at database operators rather than application developers: it turns monitoring and maintenance questions into tool calls against a live PostgreSQL instance. All operations are read-only, which the project stresses as making it safe on production and compatible with managed services such as Amazon RDS and Aurora where superuser access is unavailable; a superuser sees every database and system view, but a regular account is enough for basic monitoring. Version detection is automatic and the tool set adapts to what the server supports, spanning PostgreSQL 12 through 18. Capabilities include performance analysis and slow query identification, schema and relationship discovery, table and database bloat detection with maintenance recommendations, real-time connection and lock monitoring, background process and checkpoint analysis, replication status and WAL monitoring, database capacity reporting, and vacuum plus autovacuum effectiveness analysis across several databases at once. Version-specific features are wired in as well: enhanced I/O statistics on PostgreSQL 16 and later, the wait event catalog with descriptions and WAL summarizer monitoring for incremental backups on 17 and later, and asynchronous I/O subsystem monitoring together with per-backend I/O and WAL statistics on 18. Most tools work with no extension installed, while pg_stat_statements and the optional pg_stat_monitor extension unlock deeper query analytics. The project ships as a PyPI package and a Docker image, and the bundled docker-compose stack starts a demo PostgreSQL instance seeded with roughly 83 thousand records, the MCP server, an MCPO proxy exposing a Swagger API, and OpenWebUI so the tools can be exercised from a chat interface. Connection settings come from environment variables in a .env file. Licensed MIT.
