Postgres MCP Pro

Crystal DBA

Actively maintained PostgreSQL MCP server (Python) by Crystal DBA, 'Postgres MCP Pro', that goes beyond read-only querying to database performance and health tooling for agents: schema/object inspection, execute_sql with access modes, EXPLAIN with hypothetical-index simulation, slow-query analysis, index advising, and health checks.

MIT. ~2.9k stars. The original reference Postgres server was archived (read-only since May 2025) and only did read-only queries, so this is the canonical maintained one.
